Hi, I was wondering if anyone could help me out with a program. I've only been messing around with Java for a few weeks, so currently I suck but..

Ok. I've got an application that creates a Menu. What I want it to do, is for another program (my calculator program) to appear in the screen when you click one of the Menu Items called "Calculator". So basically I want it to kind of link to the Calculator. I guess it's something to do with this part:

public boolean action (Event evt, Object o)
     { 
      if(evt.target instanceof MenuItem)

        
        if (evt.target == calc) 
        {
        I guess something should go here.. 
        }
        
        return (false);
    }  

But I don't know how to do this. Can anyone help? It would be much appreciated!
