Some operations advance this current position past the characters processed.

Also see the documentation redistribution policy. August 30, Viewed: The following is one example of the use of the tokenizer. Below are some examples on the use of the different methods available with StringTokenizer class.

The tokenization method is much simpler than the one used by the StreamTokenizer class. An instance of StringTokenizer behaves in one of two ways, depending on whether it was created with the returnDelims flag having the value true or false: We can specify your own delimiters when we create a StringTokenizer as follows: It exists so that this class can implement the Enumeration interface.
