frame 2 inside frame 1

Question

I have 2 classes; Students and RegisterStudents, and hence 2 different main_panel(Class 1) and panel_1 (Class 2). What I am trying to do is, when a button on the Students In

Answer 1

JButton btnNewButton = new JButton("Register Student");
btnNewButton.addMouseListener(new MouseAdapter() {
   @Override
   public void mouseClicked(MouseEvent arg0) {


       Students main_panel = new Students();
       RegisterStudent panel_1 = new RegisterStudent();
       main_panel.add(panel_1);
       panel.add(main_panel); // ADD THIS LINE
   }
});
btnNewButton.setBounds(0, 162, 167, 37);
panel.add(btnNewButton);

You were initializing the new main_panel, and new panel_1, and adding panel_1 to main_panel but then you weren't doing anything with the new main_panel.

Also, I highly suggest naming your variables otherwise - these names are very non-intuitive.
