how to enforce the user to close the frame before proceed to another frame?

In general an application should only use a single main JFrame. For other popup windows you should use a JDialog. In this case you would want to use a model JDialog which will force the user to close the dialog before continuing.

sry..i dun get it....can write down some sample code?

You create JDialogs the same way you create a JFrame.

Or in your case you may be able to use a JOptionPane which creates the JDialog for you.

Start by reading the Swing tutorial on: How to Make Dialogs
