the resulting string

concat

public static String concat(Iterable<String> iterable)

Concatenate an iterable of Strings into a single String. E.g: ["1","2","3"] -> "123"

Parameters:

iterable - the iterable to be concatenated

Returns:

the resulting string

concat

public static String concat(Iterator<String> iterator)

Concatenate an iterator of Strings into a single String. E.g: ["1","2","3"] -> "123"

Parameters:

the resulting string

join

public static <T> String join(T[] array)

Joins an array of T into a String. E.g: [1,2,3] -> "123"

Type Parameters:

T - the array element type

Parameters:

array - the array to be joined

Returns:

the resulting string

join

public static <T> String join(Iterable<T> iterable)

Joins an iterable of T into a String. E.g: [1,2,3] -> "123"

Type Parameters:

T - the iterable element type

T - the iterator element type

Parameters:

iterator - the iterator to be joined

Returns:

the resulting string

interpose

public static <T,V> String interpose(T[] values,
                                     Iterator<V> separators)

Creates a string by interposing stringified values from the source array with values from the separators. E.g: interpose([1,2,3,4,5], ["-", ","]) -> "1-2,3-4,5"
