Parameter

Parameter	Description
s	the string to split
divider	the character on which to split. Occurrences of this character are not included in the output
output	an array to receive the substrings between instances of divider. It must be large enough on entry to accomodate all output. Adjacent instances of the divider character will place empty strings into output. Before returning, output is padded out with empty strings.

Declaration

public static void split(String s, char divider, String[] output)
