        while (stringTokenizer.hasMoreTokens())

             * Returns the next token from this string tokenizer.
             */

            ++i;
        }

    }
}

Output

If you want to return demiliter as a token then enter true else enter false : 
true
Total Token Count :7

Token 1 : Peter
Token 2 : &
Token 3 : is
Token 4 : &
Token 5 : playing
Token 6 : &
Token 7 : football

---------------------------------------------------------------------------------

If you want to return demiliter as a token then enter true else enter false : 
false
Total Token Count :4

Token 1 : Peter
Token 2 : is
Token 3 : playing
Token 4 : football
