I need the link the two classes I have pasted below. Please examine the code, I have created a new object of the type, the second class, but it doesnt execute when the option dialog is pressed, please advise on how i can get it to work... but classes are error free and work. Help would be much appreciated

Answer 1

Compare the code in your listenerMenu1 me = new Menu1(); // i have added this statement to open the next java file with
//the class name Menu1, but it doesnt seam to workwith the code in the main method of Menu1Menu1 window = new Menu1();
window.setTitle("Menu1");
window.pack();
window.show();See anything missing above?
