This is a dumb question but please help me anyway!

Question

I have been asked to take a class to learn to teach AP Computer Science. I was very excited to do this and was told that I didn't need prior programming knowledge to be successful. I got my first set of assignments and there are no instructions. There are just some simple programs for me to create. I went online and tried to do the best I could. I've got the first one working ok but the second one keeps giving me errors. I'm going to post what I've written below. If you have any help to offer me, please do! I am an absolute beginner so please be kind.
* @(#)MyInitials.java
* MyInitials application
* @author
* @version 1.00 2009/6/23
public class PrintInitials {
/* This program prints my initials.
public static void main(String[] args) {
System.out.println();
System.out.println("BBBBB          H H          CCCCC");
System.out.println("B B      H H          C");
System.out.println("BBBBB          HHHHH          C");
System.out.println("B B     H H          C");
System.out.println("BBBBB          H H          CCCCC");
System.out.println();
}

Here're are the error messages that came up:
Configuration: DJE - JDK version 1.6.0_14 <Default> - <Default>--------------------
java.lang.NoClassDefFoundError: PrintInitials
Caused by: java.lang.ClassNotFoundException: PrintInitials

Could not find the main class: PrintInitials. Program will exit.
Exception in thread "main"
Process completed.
Here's the code (with code tags...I think)
/**=

public class PrintInitials {
       public static void main(String[] args) {
