Controlling multiple JPanels visibility in a JFrame

Question

So what I want to do is create multiple jpanels of the different menus that i need. At first, only the visibility of the main menu is set to true. Then depending on which buttons I click, i can go to different menus by turning off the visibility of the previous menu and turning on the visibility of the current one. It's not working though, and I think it's with the way I add my JPanels. Any quick fix to this?

Answer 1

The following code may help you

JPanel mainMenu = new JPanel();
createUserMenu.setVisible(false);

JPanel createUserMenu = new JPanel();
createUserMenu.setVisible(false);

JPanel loginUserMenu = new JPanel();
loginUserMenu.setVisible(false);

ActionPerformed

      public void actionPerformed(ActionEvent e)
        {
            if(e.getSource()==btn1)
            {
                 mainMenu.setVisible(true);
                 createUserMenu.setVisible(false);
                 loginUserMenu.setVisible(false);

            }
            else  if(e.getSource()==btn2)
            {
                 mainMenu.setVisible(false);
                 createUserMenu.setVisible(true);
                 loginUserMenu.setVisible(false);

            }
            else  if(e.getSource()==btn3)
            {
                 mainMenu.setVisible(false);
                 createUserMenu.setVisible(false);
                 loginUserMenu.setVisible(true);

            } 


        }

Answer 2

Using arrayLists

components1 = new ArrayList<Component>();
    components1.add(label11);
    components1.add(label12);

to set visibility

panel1.setVisible(true);
            for (Component component1 : components1) {
                component1.setVisible(true);
            }
            panel2.setVisible(false);
            for (Component component2 : components2) {
                component2.setVisible(false);
            }
            panel3.setVisible(false);
            for (Component component : components3) {
                component.setVisible(false);
            }
