CapitalizeWords.java

I need to make my string sentence to be capitalize on each first character of word, So far haven't find such function that I can use. So made this simple class, incase someone need it. It's GPL so free to use it and modify it.

import java.util.Scanner;
import java.util.ArrayList;
import java.util.Iterator;
import java.lang.StringBuilder;
