  using countTokens() method.

     countTokens() method returns the number of tokens remaining from the current 
     delimiter set.
     It calculates the number of times StringTokenizer's nextToken() method
     can be called before it generates an exception.
     Please note that invoking countTokens() method does not advance the
     current position.

    //iterate through tokens

/*
Output Would be
Remaining Tokens : 5
Java
Remaining Tokens : 4
StringTokenizer
Remaining Tokens : 3
count
Remaining Tokens : 2
Tokens
Remaining Tokens : 1
