The repaint() method is used to update the graphics on a component, such as a panel or frame. Calling repaint() in the actionPerformed() method will trigger the screen to refresh and update the graphics based on any changes to the panel. The paint(), paintComponent(), and paintBorder() methods are used for painting on the component, but calling these methods directly is not recommended as they may result in unexpected behavior.
