Yes, it will help show just how bad a beginner's code can be. If you enjoy schoolboy howlers like these then go ahead and feast on Vaibhav's code. if you want to score more than an "E" on your assignment then write something yourself.

public static void main(String args[])throws IOException
{ 
... (implements the whole program in this one method)
}

...

if((cm.compareTo("bye")==0)||(m.compareTo("bye")==0))
{flag=true;
}

...

wait=true;
while(wait);

...

 while(!flag)

 ...

 if(e.getActionCommand()=="send")

 ...

 catch(IOException e)   {
 System.out.println("exception occoured !");
 }
