I need to make my popup class observable and the main frame class observer. When the user clicks the ok button on the popup, I need the string from the popup's textfield returned to my main program.

Main fram class.

Also, if anyone could show an example of the above code using a listener class without making it an inner-class, it would be appreciated. Thats the only way my professors taught it, and my degree doesn't have any more java classes scheduled for it. So if you're wondering, no this isn't a homework assignment.

Nobody knows? Haven't found a forum yet that can answer this.

Can Anyone Please How can i run this program?
Is it a Applet Program or Application Program?
If so,How to run this ?
Thank You
