StreamTokenizer From the API The StreamTokenizer class takes an input stream and parses it into "tokens", allowing the tokens to be read one at a time. For example with String str="A string containing 5 tokens" If you use StreamTokenizer you 'll get 5 tokens that you may use. 1st token is 'A' 2nd token is 'string' 3rd token is 'containing' 4th token is '5' 5th token is 'tokens' I Hope it helps!
By constantly trying one ends up succeeding. Thus: the more one fails the more one has a chance to succeed.
