printing letters using threads, concurrent programming. Java
<p>Write a program that creates three thread: one to print letter A ten times, second to print letter B five times, and the third one to print out integers from 1 t0 10. After creating the three threads, the main program should terminate. In your solution , adopt the following structure.</p>

<pre><code>public class PrintChar implements Runnable
{
  /** field(s) **/
  /** constructor(s)**/
  /**method(s)**/
}

public class PrintNum implements Runnable
{
 /** field(s) **/
 /** constructor(s)**/
 /**method(s)**/
}

public class PrintDemo
{
   public static void main(String[] args)
  {
    /**method's code **/
  }
}
</code></pre>

<p>would be really really really greatful if someone could give me the answer and shed some light for me. Pretty please..</p>
