Creating another class window within one class

Question

Ok I have a main window class, at some point if you click some button I want it to make the first window invisible and have this other, second class, appear, and further on, for both to talk to eachother. These are applets, and I have tried having one applet launch using applet.init() and hoping it would launch but it doesn't work that easy.

Answer 1

so it has to create a new window within the first class? I cannot use two classes? here:
