Asking urgent help for UI problems

Question

Hope to get any reply and help from you!
Now, as for the UIs we want to get, we require that when users press one button on UI1 with "Enter" in keyboard(not using mouse), another UI2 would appear in front. Moreover, when users press "ESC" in keyboard, it can also return back from UI2 to UI1.
However, we have some following problems as below:
1. Now we use the following way for ui programming. However, we always find that the UI would be dead without any response for any key press. What's wrong with the following porgramming style and way:
//UI1 class
dispse();
UI2 ui2 = new UI2();
ui2.setVisible(true);
//UI2 class
dispse();
UI1 ui1 = new UI1();
ui1.setVisible(true); Many thanks for you! I hope it would not cost you much time!
best wishes for you!

Answer 1

Sorry if the code is rather long. However most of them are for the design of GUI only.
Thanks in advance.
