What a StringTokenizer do

A StringTokenizer takes a String as a parameter in the constructor
Then you can separate each words of the String (Unless the separator you've choosen is space)
In other words, you can take out all the subString that are beetween two separators in one big String

I think you are talking about the Split Function.

This will split up a string into an array of strings, based on a delimeter.

For example. You could break up on spaces or cariage returns.

That's it !
