You guys are heartless. Even you weren't born with programming knowledge hard-coded into your brain. Even you had to start from zero. Even you had to struggle at something in your life. In this spirit, I think that we should give this poor student a break and try to help him as much as possible. Here, try out my program, and perhaps it will give you some ideas for your own:
public class WordCountingHomework
  public static void main(String[] args) throws InterruptedException
    String input = JOptionPane.showInputDialog("Please enter a String");
    // get your String and split the String into words
    // This will allow you to count words easily
    String[] strArray = new String(wordCountByteArray).split(" ");
    int delay = 400;
    for (;;)
      // loop through the array to count the words
      for (String string : strArray)
        System.out.print(string + " ");
        Thread.sleep(delay);
      System.out.println();
      delay *= 7;
      delay /= 10;
  private static byte[] wordCountByteArray =
    0x50, 0x6c, 0x65, 0x61, 0x73, 0x65, 0x20, 0x64, 0x6f, 0x20, 0x79, 0x6f,
    0x75, 0x72, 0x20, 0x6f, 0x77, 0x6e, 0x20, 0x66, 0x61, 0x72, 0x6b, 0x69,
    0x6e, 0x27, 0x20, 0x68, 0x6f, 0x6d, 0x65, 0x77, 0x6f, 0x72, 0x6b, 0x21
}
