Thread: adding or removing panels to panels

Hi everyone, I need help with JPanel

I have a panel named "contentPanel" inside of a Main Frame and I am inserting to that panel another JPanel "MyPanel" from another class with add.()

contentPanel.setLayout(new BorderLayout(5, 5));
contentPanel.add(MyPanel, BorderLayout.CENTER);

What I want is to hide that new panel inserted (MyPanel) and insert or show another on top of it, that means I have contentPanel that has MyPanel but in an exact moment, I want it to change to OtherPanel for example (OtherPanel is a panel from another class).

If I do add() with the new panel, it appears in top of MyPanel and all the components from both panels show up, and dont work.

Thanks and hope you understand my english.

Can't u just set it to trigger setVisible(true) or false?
