Question

Explain the use of repaint ( ).

Answer 1

The repaint() method is asynchronous.

- The repaint() requests an erase and redraw (update) after a small time delay.

- When you invoke repaint(), a message is sent to the native GUI requesting it to perform the action sometime in the distant future.

- This method does not invoke paint() method directly.
