public final class LocalDate
extends ChronoLocalDate
implements Temporal, TemporalAdjuster, java.io.Serializable
```
A date without a time-zone in the ISO-8601 calendar system, such as 2007-12-03.
LocalDate is an immutable date-time object that represents a date, often viewed as year-month-day. Other date fields, such as day-of-year, day-of-week and week-of-year, can also be accessed. For example, the value "2nd October 2007" can be stored in a LocalDate.
This class does not store or represent a time or time-zone. Instead, it is a description of the date, as used for birthdays. It cannot represent an instant on the time-line without additional information such as an offset or time-zone.
The ISO-8601 calendar system is the modern civil calendar system used today in most of the world. It is equivalent to the proleptic Gregorian calendar system, in which today's rules for leap years are applied for all time. For most applications written today, the ISO-8601 rules are entirely suitable. However, any application that makes use of historical dates, and requires them to be accurate will find the ISO-8601 approach unsuitable.
Specification for implementors
This class is immutable and thread-safe.

  - from
```
public static LocalDate from(TemporalAccessor temporal)
```
    Obtains an instance of LocalDate from a temporal object.
    A TemporalAccessor represents some form of date and time information. This factory converts the arbitrary temporal object to an instance of LocalDate.
    The conversion uses the TemporalQueries.localDate() query, which relies on extracting the EPOCH_DAY field.
    This method matches the signature of the functional interface TemporalQuery allowing it to be used as a query via method reference, LocalDate::from.
    
    Parameters:
    temporal - the temporal object to convert, not null
    
    Returns:
    the local date, not null
    
    Throws:
    
    DateTimeException - if unable to convert to a LocalDate
  - parse
```
public static LocalDate parse(java.lang.CharSequence text)
```
    Obtains an instance of LocalDate from a text string such as 2007-12-03.
    The string must represent a valid date and is parsed using java.time.format.DateTimeFormatters#isoLocalDate().
    
    Parameters:
    text - the text to parse such as "2007-12-03", not null
    
    Returns:
    the parsed local date, not null
    
    Throws:
    
    DateTimeParseException - if the text cannot be parsed

    Obtains an instance of LocalDate from a text string using a specific formatter.
    The text is parsed using the formatter, returning a date.
    
    Parameters:
    text - the text to parse, not null
    formatter - the formatter to use, not null
    
    Returns:
    the parsed local date, not null
    
    Throws:
    
    DateTimeParseException - if the text cannot be parsed
  - isSupported
```
public boolean isSupported(TemporalField field)
```
    Checks if the specified field is supported.
    This checks if this date can be queried for the specified field. If false, then calling the range and get methods will throw an exception.
    If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this date-time. The supported fields are:
    - DAY_OF_WEEK
    - ALIGNED_DAY_OF_WEEK_IN_MONTH
    - ALIGNED_DAY_OF_WEEK_IN_YEAR
    - DAY_OF_MONTH
    - DAY_OF_YEAR
    - EPOCH_DAY
    - ALIGNED_WEEK_OF_MONTH
    - ALIGNED_WEEK_OF_YEAR
    - MONTH_OF_YEAR
    - EPOCH_MONTH
    - YEAR_OF_ERA
    - YEAR
    - ERA
    All other ChronoField instances will return false.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.isSupportedBy(TemporalAccessor) passing this as the argument. Whether the field is supported is determined by the field.
    Specified by:
    
    isSupported in interface TemporalAccessor
    
    Overrides:
    
    isSupported in class ChronoLocalDate
    
    Parameters:
    field - the field to check, null returns false
    
    Returns:
    true if the field is supported on this date, false if not
  - range
```
public ValueRange range(TemporalField field)
```
    Gets the range of valid values for the specified field.
    The range object expresses the minimum and maximum valid values for a field. This date is used to enhance the accuracy of the returned range. If it is not possible to return the range, because the field is not supported or for some other reason, an exception is thrown.
    If the field is a ChronoField then the query is implemented here. The supported fields will return appropriate range instances. All other ChronoField instances will throw a DateTimeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.rangeRefinedBy(TemporalAccessor) passing this as the argument. Whether the range can be obtained is determined by the field.
    
    Specified by:
    
    range in interface TemporalAccessor
    
    Overrides:
    
    range in class DefaultInterfaceTemporalAccessor
    
    Parameters:
    field - the field to query the range for, not null
    
    Returns:
    the range of valid values for the field, not null
    
    Throws:
    
    DateTimeException - if the range for the field cannot be obtained
  - get
```
public int get(TemporalField field)
```
    Gets the value of the specified field from this date as an int.
    This queries this date for the value for the specified field. The returned value will always be within the valid range of values for the field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.
    If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this date, except EPOCH_DAY and EPOCH_MONTH which are too large to fit in an int and throw a DateTimeException. All other ChronoField instances will throw a DateTimeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.
    
    Specified by:
    
    get in interface TemporalAccessor
    
    Overrides:
    
    get in class DefaultInterfaceTemporalAccessor
    
    Parameters:
    field - the field to get, not null
    
    Returns:
    the value for the field
    
    Throws:
    
    DateTimeException - if a value for the field cannot be obtained
    
    java.lang.ArithmeticException - if numeric overflow occurs
  - getLong
```
public long getLong(TemporalField field)
```
    Gets the value of the specified field from this date as a long.
    This queries this date for the value for the specified field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.
    If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this date. All other ChronoField instances will throw a DateTimeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.
    
    Specified by:
    
    getLong in interface TemporalAccessor
    
    Parameters:
    field - the field to get, not null
    
    Returns:
    the value for the field
    
    Throws:
    
    DateTimeException - if a value for the field cannot be obtained
    
    java.lang.ArithmeticException - if numeric overflow occurs
  - getChronology
```
public IsoChronology getChronology()
```
    Gets the chronology of this date, which is the ISO calendar system.
    The Chronology represents the calendar system in use. The ISO-8601 calendar system is the modern civil calendar system used today in most of the world. It is equivalent to the proleptic Gregorian calendar system, in which todays's rules for leap years are applied for all time.
    
    Specified by:
    
    getChronology in class ChronoLocalDate
    
    Returns:
    the ISO chronology, not null
  - getEra
```
public Era getEra()
```
    Gets the era applicable at this date.
    The official ISO-8601 standard does not define eras, however IsoChronology does. It defines two eras, 'CE' from year one onwards and 'BCE' from year zero backwards. Since dates before the Julian-Gregorian cutover are not in line with history, the cutover between 'BCE' and 'CE' is also not aligned with the commonly used eras, often referred to using 'BC' and 'AD'.
    Users of this class should typically ignore this method as it exists primarily to fulfill the ChronoLocalDate contract where it is necessary to support the Japanese calendar system.
    The returned era will be a singleton capable of being compared with the constants in IsoChronology using the == operator.
    
    Overrides:
    
    getEra in class ChronoLocalDate
    
    Returns:
    the IsoChronology era constant applicable at this date, not null
  - getYear
```
public int getYear()
```
    Gets the year field.
    This method returns the primitive int value for the year.
    The year returned by this method is proleptic as per get(YEAR). To obtain the year-of-era, use get(YEAR_OF_ERA.
    
    Returns:
    the year, from MIN_YEAR to MAX_YEAR
  - getMonthValue
```
public int getMonthValue()
```
    Gets the month-of-year field from 1 to 12.
    This method returns the month as an int from 1 to 12. Application code is frequently clearer if the enum Month is used by calling getMonth().
    
    Returns:
    the month-of-year, from 1 to 12
    See Also:
    getMonth()
  - getMonth
```
public Month getMonth()
```
    Gets the month-of-year field using the Month enum.
    This method returns the enum Month for the month. This avoids confusion as to what int values mean. If you need access to the primitive int value then the enum provides the int value.
    
    Returns:
    the month-of-year, not null
    See Also:
    getMonthValue()
  - getDayOfMonth
```
public int getDayOfMonth()
```
    Gets the day-of-month field.
    This method returns the primitive int value for the day-of-month.
    
    Returns:
    the day-of-month, from 1 to 31
  - getDayOfYear
```
public int getDayOfYear()
```
    Gets the day-of-year field.
    This method returns the primitive int value for the day-of-year.
    
    Returns:
    the day-of-year, from 1 to 365, or 366 in a leap year
  - getDayOfWeek
```
public DayOfWeek getDayOfWeek()
```
    Gets the day-of-week field, which is an enum DayOfWeek.
    This method returns the enum DayOfWeek for the day-of-week. This avoids confusion as to what int values mean. If you need access to the primitive int value then the enum provides the int value.
    Additional information can be obtained from the DayOfWeek. This includes textual names of the values.
    
    Returns:
    the day-of-week, not null
  - isLeapYear
```
public boolean isLeapYear()
```
    Checks if the year is a leap year, according to the ISO proleptic calendar system rules.
    This method applies the current rules for leap years across the whole time-line. In general, a year is a leap year if it is divisible by four without remainder. However, years divisible by 100, are not leap years, with the exception of years divisible by 400 which are.
    For example, 1904 is a leap year it is divisible by 4. 1900 was not a leap year as it is divisible by 100, however 2000 was a leap year as it is divisible by 400.
    The calculation is proleptic - applying the same rules into the far future and far past. This is historically inaccurate, but is correct for the ISO-8601 standard.
    
    Overrides:
    
    isLeapYear in class ChronoLocalDate
    
    Returns:
    true if the year is leap, false otherwise
  - lengthOfMonth
```
public int lengthOfMonth()
```
    Returns the length of the month represented by this date.
    This returns the length of the month in days. For example, a date in January would return 31.
    
    Specified by:
    
    lengthOfMonth in class ChronoLocalDate
    
    Returns:
    the length of the month in days
  - lengthOfYear
```
public int lengthOfYear()
```
    Returns the length of the year represented by this date.
    This returns the length of the year in days, either 365 or 366.
    
    Overrides:
    
    lengthOfYear in class ChronoLocalDate
    
    Returns:
    366 if the year is leap, 365 otherwise
  - with
```
public LocalDate with(TemporalAdjuster adjuster)
```
    Returns an adjusted copy of this date.
    This returns a new LocalDate, based on this one, with the date adjusted. The adjustment takes place using the specified adjuster strategy object. Read the documentation of the adjuster to understand what adjustment will be made.
    A simple adjuster might simply set the one of the fields, such as the year field. A more complex adjuster might set the date to the last day of the month. A selection of common adjustments is provided in TemporalAdjusters. These include finding the "last day of the month" and "next Wednesday". Key date-time classes also implement the TemporalAdjuster interface, such as Month and MonthDay. The adjuster is responsible for handling special cases, such as the varying lengths of month and leap years.
    For example this code returns a date on the last day of July:
```
  import static java.bp.Month.*;
  import static java.bp.temporal.Adjusters.*;

  result = localDate.with(JULY).with(lastDayOfMonth());
 
```
    The result of this method is obtained by invoking the TemporalAdjuster.adjustInto(Temporal) method on the specified adjuster passing this as the argument.
    This instance is immutable and unaffected by this method call.
    Specified by:
    
    with in interface Temporal
    
    Overrides:
    
    with in class ChronoLocalDate
    
    Parameters:
    adjuster - the adjuster to use, not null
    
    Returns:
    a LocalDate based on this with the adjustment made, not null
    
    Throws:
    
    DateTimeException - if the adjustment cannot be made
    
    java.lang.ArithmeticException - if numeric overflow occurs
  - with
```
public LocalDate with(TemporalField field,
             long newValue)
```
    Returns a copy of this date with the specified field set to a new value.
    This returns a new LocalDate, based on this one, with the value for the specified field changed. This can be used to change any supported field, such as the year, month or day-of-month. If it is not possible to set the value, because the field is not supported or for some other reason, an exception is thrown.
    In some cases, changing the specified field can cause the resulting date to become invalid, such as changing the month from 31st January to February would make the day-of-month invalid. In cases like this, the field is responsible for resolving the date. Typically it will choose the previous valid date, which would be the last valid day of February in this example.
    If the field is a ChronoField then the adjustment is implemented here. The supported fields behave as follows:
    - DAY_OF_WEEK - Returns a LocalDate with the specified day-of-week. The date is adjusted up to 6 days forward or backward within the boundary of a Monday to Sunday week.
    - ALIGNED_DAY_OF_WEEK_IN_MONTH - Returns a LocalDate with the specified aligned-day-of-week. The date is adjusted to the specified month-based aligned-day-of-week. Aligned weeks are counted such that the first week of a given month starts on the first day of that month. This may cause the date to be moved up to 6 days into the following month.
    - ALIGNED_DAY_OF_WEEK_IN_YEAR - Returns a LocalDate with the specified aligned-day-of-week. The date is adjusted to the specified year-based aligned-day-of-week. Aligned weeks are counted such that the first week of a given year starts on the first day of that year. This may cause the date to be moved up to 6 days into the following year.
    - DAY_OF_MONTH - Returns a LocalDate with the specified day-of-month. The month and year will be unchanged. If the day-of-month is invalid for the year and month, then a DateTimeException is thrown.
    - DAY_OF_YEAR - Returns a LocalDate with the specified day-of-year. The year will be unchanged. If the day-of-year is invalid for the year, then a DateTimeException is thrown.
    - EPOCH_DAY - Returns a LocalDate with the specified epoch-day. This completely replaces the date and is equivalent to ofEpochDay(long).
    - ALIGNED_WEEK_OF_MONTH - Returns a LocalDate with the specified aligned-week-of-month. Aligned weeks are counted such that the first week of a given month starts on the first day of that month. This adjustment moves the date in whole week chunks to match the specified week. The result will have the same day-of-week as this date. This may cause the date to be moved into the following month.
    - ALIGNED_WEEK_OF_YEAR - Returns a LocalDate with the specified aligned-week-of-year. Aligned weeks are counted such that the first week of a given year starts on the first day of that year. This adjustment moves the date in whole week chunks to match the specified week. The result will have the same day-of-week as this date. This may cause the date to be moved into the following year.
    - MONTH_OF_YEAR - Returns a LocalDate with the specified month-of-year. The year will be unchanged. The day-of-month will also be unchanged, unless it would be invalid for the new month and year. In that case, the day-of-month is adjusted to the maximum valid value for the new month and year.
    - PROLEPTIC_MONTH - Returns a LocalDate with the specified proleptic-month. The day-of-month will be unchanged, unless it would be invalid for the new month and year. In that case, the day-of-month is adjusted to the maximum valid value for the new month and year.
    - YEAR_OF_ERA - Returns a LocalDate with the specified year-of-era. The era and month will be unchanged. The day-of-month will also be unchanged, unless it would be invalid for the new month and year. In that case, the day-of-month is adjusted to the maximum valid value for the new month and year.
    - YEAR - Returns a LocalDate with the specified year. The month will be unchanged. The day-of-month will also be unchanged, unless it would be invalid for the new month and year. In that case, the day-of-month is adjusted to the maximum valid value for the new month and year.
    - ERA - Returns a LocalDate with the specified era. The year-of-era and month will be unchanged. The day-of-month will also be unchanged, unless it would be invalid for the new month and year. In that case, the day-of-month is adjusted to the maximum valid value for the new month and year.
    In all cases, if the new value is outside the valid range of values for the field then a DateTimeException will be thrown.
    All other ChronoField instances will throw a DateTimeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.adjustInto(Temporal, long) passing this as the argument. In this case, the field determines whether and how to adjust the instant.
    This instance is immutable and unaffected by this method call.

  - query
```
public <R> R query(TemporalQuery<R> query)
```
    Queries this date using the specified query.
    This queries this date using the specified query strategy object. The TemporalQuery object defines the logic to be used to obtain the result. Read the documentation of the query to understand what the result of this method will be.
    The result of this method is obtained by invoking the TemporalQuery.queryFrom(TemporalAccessor) method on the specified query passing this as the argument.
    
    Specified by:
    
    query in interface TemporalAccessor

    R - the type of the result
    Parameters:
    query - the query to invoke, not null
    
    Returns:
    the query result, null may be returned (defined by the query)

  - adjustInto
```
public Temporal adjustInto(Temporal temporal)
```
    Adjusts the specified temporal object to have the same date as this object.
    This returns a temporal object of the same observable type as the input with the date changed to be the same as this.
    The adjustment is equivalent to using Temporal.with(TemporalField, long) passing ChronoField.EPOCH_DAY as the field.
    In most cases, it is clearer to reverse the calling pattern by using Temporal.with(TemporalAdjuster):
```
   // these two lines are equivalent, but the second approach is recommended
   temporal = thisLocalDate.adjustInto(temporal);
   temporal = temporal.with(thisLocalDate);
 
```
    This instance is immutable and unaffected by this method call.
    Specified by:
    
    adjustInto in interface TemporalAdjuster
    
    Overrides:
    
    adjustInto in class ChronoLocalDate
    
    Parameters:
    temporal - the target object to be adjusted, not null
    
    Returns:
    the adjusted object, not null
    
    Throws:
    
    DateTimeException - if unable to make the adjustment
    
    java.lang.ArithmeticException - if numeric overflow occurs
  - until
```
public long until(Temporal endExclusive,
         TemporalUnit unit)
```
    Calculates the period between this date and another date in terms of the specified unit.
    This calculates the period between two dates in terms of a single unit. The start and end points are this and the specified date. The result will be negative if the end is before the start. The Temporal passed to this method must be a LocalDate. For example, the period in days between two dates can be calculated using startDate.until(endDate, DAYS).
    The calculation returns a whole number, representing the number of complete units between the two dates. For example, the period in months between 2012-06-15 and 2012-08-14 will only be one month as it is one day short of two months.
    This method operates in association with TemporalUnit.between(java.time.temporal.Temporal, java.time.temporal.Temporal). The result of this method is a long representing the amount of the specified unit. By contrast, the result of between is an object that can be used directly in addition/subtraction:
```
   long period = start.until(end, MONTHS);   // this method
   dateTime.plus(MONTHS.between(start, end));      // use in plus/minus
 
```
    The calculation is implemented in this method for ChronoUnit. The units DAYS, WEEKS, MONTHS, YEARS, DECADES, CENTURIES, MILLENNIA and ERAS are supported. Other ChronoUnit values will throw an exception.
    If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.between(Temporal, Temporal) passing this as the first argument and the input temporal as the second argument.
    This instance is immutable and unaffected by this method call.
    Specified by:
    
    until in interface Temporal
    
    Parameters:
    endExclusive - the end date, which is converted to a LocalDate, not null
    unit - the unit to measure the period in, not null
    
    Returns:
    the amount of the period between this date and the end date
    
    Throws:
    
    DateTimeException - if the period cannot be calculated
    
    java.lang.ArithmeticException - if numeric overflow occurs
  - until
```
public Period until(ChronoLocalDate endDate)
```
    Calculates the period between this date and another date as a Period.
    This calculates the period between two dates in terms of years, months and days. The start and end points are this and the specified date. The result will be negative if the end is before the start.
    The calculation is performed using the ISO calendar system. If necessary, the input date will be converted to ISO.
    The start date is included, but the end date is not. The period is calculated by removing complete months, then calculating the remaining number of days, adjusting to ensure that both have the same sign. The number of months is then normalized into years and months based on a 12 month year. A month is considered to be complete if the end day-of-month is greater than or equal to the start day-of-month. For example, from 2010-01-15 to 2011-03-18 is "1 year, 2 months and 3 days".
    The result of this method can be a negative period if the end is before the start. The negative sign will be the same in each of year, month and day.
    There are two equivalent ways of using this method. The first is to invoke this method. The second is to use Period.between(LocalDate, LocalDate):
```
   // these two lines are equivalent
   period = start.until(end);
   period = Period.between(start, end);
 
```
    The choice should be made based on which makes the code more readable.
    Specified by:
    
    until in class ChronoLocalDate
    
    Parameters:
    endDate - the end date, exclusive, which may be in any chronology, not null
    
    Returns:
    the period between this date and the end date, not null

    This returns a LocalDateTime formed from this date at the specified hour, minute, second and nanosecond. The individual time fields must be within their valid range. All possible combinations of date and time are valid.
    
    Parameters:
    hour - the hour-of-day to use, from 0 to 23
    minute - the minute-of-hour to use, from 0 to 59
    second - the second-of-minute to represent, from 0 to 59
    nanoOfSecond - the nano-of-second to represent, from 0 to 999,999,999
    
    Returns:
    the local date-time formed from this date and the specified time, not null
    
    Throws:
    
    DateTimeException - if the value of any field is out of range
  - atTime
```
public OffsetDateTime atTime(OffsetTime time)
```
    Combines this date with an offset time to create an OffsetDateTime.
    This returns an OffsetDateTime formed from this date at the specified time. All possible combinations of date and time are valid.
    
    Parameters:
    time - the time to combine with, not null
    
    Returns:
    the offset date-time formed from this date and the specified time, not null
  - atStartOfDay
```
public LocalDateTime atStartOfDay()
```
    Combines this date with the time of midnight to create a LocalDateTime at the start of this date.
    This returns a LocalDateTime formed from this date at the time of midnight, 00:00, at the start of this date.
    
    Returns:
    the local date-time of midnight at the start of this date, not null
  - atStartOfDay
```
public ZonedDateTime atStartOfDay(ZoneId zone)
```
    Combines this date with a time-zone to create a ZonedDateTime at the start of the day
    This returns a ZonedDateTime formed from this date at the specified zone, with the time set to be the earliest valid time according to the rules in the time-zone.
    Time-zone rules, such as daylight savings, mean that not every local date-time is valid for the specified zone, thus the local date-time may not be midnight.
    In most cases, there is only one valid offset for a local date-time. In the case of an overlap, there are two valid offsets, and the earlier one is used, corresponding to the first occurrence of midnight on the date. In the case of a gap, the zoned date-time will represent the instant just after the gap.
    If the zone ID is a ZoneOffset, then the result always has a time of midnight.
    To convert to a specific time in a given time-zone call atTime(LocalTime) followed by LocalDateTime.atZone(ZoneId).
    
    Parameters:
    zone - the zone ID to use, not null
    
    Returns:
    the zoned date-time formed from this date and the earliest valid time for the zone, not null
  - toEpochDay
```
public long toEpochDay()
```
    Description copied from class: ChronoLocalDate
    
    Converts this date to the Epoch Day.
    The Epoch Day count is a simple incrementing count of days where day 0 is 1970-01-01 (ISO). This definition is the same for all chronologies, enabling conversion.
    
    Overrides:
    
    toEpochDay in class ChronoLocalDate
    
    Returns:
    the Epoch Day equivalent to this date
  - compareTo
```
public int compareTo(ChronoLocalDate other)
```
    Compares this date to another date.
    The comparison is primarily based on the date, from earliest to latest. It is "consistent with equals", as defined by Comparable.
    If all the dates being compared are instances of LocalDate, then the comparison will be entirely based on the date. If some dates being compared are in different chronologies, then the chronology is also considered, see ChronoLocalDate.compareTo(java.time.chrono.ChronoLocalDate).
    
    Specified by:
    
    compareTo in interface java.lang.Comparable<ChronoLocalDate>
    
    Overrides:
    
    compareTo in class ChronoLocalDate
    
    Parameters:
    other - the other date to compare to, not null
    
    Returns:
    the comparator value, negative if less, positive if greater
  - isAfter
```
public boolean isAfter(ChronoLocalDate other)
```
    Checks if this date is after the specified date.
    This checks to see if this date represents a point on the local time-line after the other date.
```
   LocalDate a = LocalDate.of(2012, 6, 30);
   LocalDate b = LocalDate.of(2012, 7, 1);
   a.isAfter(b) == false
   a.isAfter(a) == false
   b.isAfter(a) == true
 
```
    This method only considers the position of the two dates on the local time-line. It does not take into account the chronology, or calendar system. This is different from the comparison in compareTo(ChronoLocalDate), but is the same approach as ChronoLocalDate.DATE_COMPARATOR.
    Overrides:
    
    isAfter in class ChronoLocalDate
    
    Parameters:
    other - the other date to compare to, not null
    
    Returns:
    true if this date is after the specified date
  - isBefore
```
public boolean isBefore(ChronoLocalDate other)
```
    Checks if this date is before the specified date.
    This checks to see if this date represents a point on the local time-line before the other date.
```
   LocalDate a = LocalDate.of(2012, 6, 30);
   LocalDate b = LocalDate.of(2012, 7, 1);
   a.isBefore(b) == true
   a.isBefore(a) == false
   b.isBefore(a) == false
 
```
    This method only considers the position of the two dates on the local time-line. It does not take into account the chronology, or calendar system. This is different from the comparison in compareTo(ChronoLocalDate), but is the same approach as ChronoLocalDate.DATE_COMPARATOR.
    Overrides:
    
    isBefore in class ChronoLocalDate
    
    Parameters:
    other - the other date to compare to, not null
    
    Returns:
    true if this date is before the specified date
  - isEqual
```
public boolean isEqual(ChronoLocalDate other)
```
    Checks if this date is equal to the specified date.
    This checks to see if this date represents the same point on the local time-line as the other date.
```
   LocalDate a = LocalDate.of(2012, 6, 30);
   LocalDate b = LocalDate.of(2012, 7, 1);
   a.isEqual(b) == false
   a.isEqual(a) == true
   b.isEqual(a) == false
 
```
    This method only considers the position of the two dates on the local time-line. It does not take into account the chronology, or calendar system. This is different from the comparison in compareTo(ChronoLocalDate) but is the same approach as ChronoLocalDate.DATE_COMPARATOR.
    Overrides:
    
    isEqual in class ChronoLocalDate
    
    Parameters:
    other - the other date to compare to, not null
    
    Returns:
    true if this date is equal to the specified date
  - equals
```
public boolean equals(java.lang.Object obj)
```
    Checks if this date is equal to another date.
    Compares this LocalDate with another ensuring that the date is the same.
    Only objects of type LocalDate are compared, other types return false. To compare the dates of two TemporalAccessor instances, including dates in two different chronologies, use ChronoField.EPOCH_DAY as a comparator.
    
    Overrides:
    
    equals in class ChronoLocalDate
    
    Parameters:
    obj - the object to check, null returns false
    
    Returns:
    true if this is equal to the other date
  - hashCode
```
public int hashCode()
```
    A hash code for this date.
    
    Overrides:
    
    hashCode in class ChronoLocalDate
    
    Returns:
    a suitable hash code
  - toString
```
public java.lang.String toString()
```
    Outputs this date as a String, such as 2007-12-03.
    The output will be in the ISO-8601 format yyyy-MM-dd.
    
    Overrides:
    
    toString in class ChronoLocalDate
    
    Returns:
    a string representation of this date, not null
  - format
```
public java.lang.String format(DateTimeFormatter formatter)
```
    Outputs this date as a String using the formatter.
    This date will be passed to the formatter print method.
    
    Overrides:
    
    format in class ChronoLocalDate
    
    Parameters:
    formatter - the formatter to use, not null
    
    Returns:
    the formatted date string, not null
    
    Throws:
    
    DateTimeException - if an error occurs during printing
