• split

  public static String[] split(String value, char delim)

  Splits a separated string into an array of String tokens. If the input string is null, this method returns null.

  Implementation note: for performance reasons, this implementation uses neither StringTokenizer nor String.split(). StringTokenizer does not return all tokens for strings of the form "1,2,,3," unless you use an instance that returns the separator. By doing so, our code would need to modify the token string which would create another temporary object and would make this method very slow.
  String.split does not return all tokens for strings of the form "1,2,3,,,". We simply cannot use this method.

  The result is a custom String splitter algorithm which performs well for large Strings.

  Parameters:

  value - the string value to split into tokens

  Returns:

  an array of String Objects or null if the string value is null
