Constructor Detail

MiniSet5

public MiniSet5(T value0,
                T value1,
                T value2,
                T value3,
                T value4)

Parameters:

value0 - the first value

value1 - the second value

value2 - the third value

value3 - the fourth value

value4 - the fifth value

Method Detail

size

public int size()

Get the number of values (always five).

Returns:

the number of values

isEmpty

public boolean isEmpty()

Return false to indicate that the set is not empty.

Returns:

false

contains

public boolean contains(Object o)

Test whether the collection contains an object equal to the specified value.

Parameters:

o - the object

Returns:

true if any of the five values is equal to the object

iterator

public Iterator<T> iterator()

Return an Iterator over the set.

Returns:

the Iterator

toArray

public Object[] toArray()

Copy the set to an array.

Returns:

an array containing the values

toArray

public <TT> TT[] toArray(TT[] a)

Copy the set to an array, either the supplied array (if it fits) or a new array of the specified type.

Type Parameters:

TT - the type of the destination array items

Parameters:

a - the destination array

Returns:

a copy of the set, in a new array if necessary

Throws:

ArrayStoreException - if the values in the collection can't be stored in the destination array

equals

public boolean equals(Object other)

Compares the specified object with this set for equality. Returns true if the specified object is also a set containing five values identical to those of this set.

Specified by:

equals in interface Collection<T>

equals in interface Set<T>

Overrides:

equals in class MiniSet<T>

Parameters:

other - object to be compared for equality with this set

Returns:

true if the specified object is equal to this set

hashCode

public int hashCode()

Returns the hash code value for this set. The hash code of a set is defined to be the sum of the hash codes of the elements in the set.

Specified by:

hashCode in interface Collection<T>

Specified by:

hashCode in interface Set<T>

Overrides:

hashCode in class MiniSet<T>

Returns:

the hash code value for this set

toString
