Name	Syntax	Description
concat	String concat(String separator, String ... strs)	Concatenates the given varargs-array of strings into a single string using the given separator.
concat	String[] concat(String colSepar, String rowSepar, String[]... matr)	Concatenates the given string matrix (which can be given as a varargs of rows) into a single string. Puts colSepar between values of columns of a row, and rowSepar between rows.
contains	boolean contains(String[] strs, String str)	Returns true if the given string array strs contains the given string str.
find	int[] find(String[] strs, String str)	Returns an array with the indices to all occurrences of str in strs.
findIn	int findIn(String[] strs, String str)	Returns the index to the first occurrence of str in strs or -1 if no match.
findIn	int findIn(String str, String toFind)	Returns the first index of str that is the start of the substring toFind. If there is no substring matching toFind in str, -1 is returned.
length	int length(String str)	Returns the length of the string str.
replace	String replace(String str, String orig, String replacement)	Returns a string where orig has been replaced by replacement.
split	String[] split(String str)	Returns an array of strings by splitting the given string at spaces.
split	String[] split(String str, String separator)	Returns an array of strings by splitting the given string at the given separator.
substring	String substring(String str, int start, int length)	Returns a substring with the given length starting at the given position.
unique	String[] unique(String[] strs)	Returns an array of strings with the unique values in the given array of strings.
