Question

I have a running java GUI application right now in a single class file, in this application I have a button that when clicked it is used to instantiate and display a separate form from a different class file in the same project. I am confused with how I actually access this other .java file in order to instantiate and display the form from it. Hope you can help.
Thanks, Beef

How do you access any class file? JFrame, JPanel, JTextField are all examples of Java source code contained in separate files. You would use:

JFrame frame = new JFrame();
JPanel panel = new JPanel();
JTextField textField = new JTextField();

So to access your custom form your would use:

CustomForm form = new CustomForm();

As long as the class file is found on your classpath it should not be a problem.

If you are having compile or run time problems then you need to display the message so we can give further help.
