public class Frame extends          


        

Answer 1

1. don't to use AbsoluteLayout

2. change validate(); in actionPerformed to contain.validate(); and follows with contain.repaint();

3. rename class name (reserved Java word, or methods name) Frame (java.awt.Frame) to MyFrame (for example)

4. use CardLayout instead of remove and then add a new JPanel on runtime
