What would happen if the call to super.paintComponent were removed from the paintComponent method of the CoordinatesPanel class? Remove it and run the program to test your answer.
What will be an ideal response?
The paintComponent method is a member of class CoordinatesPanel which extends JPanel which means that the call to super.paintComponent is a call to the paintComponent method of the JPanel class. Without this call, the paintComponent method of the JPanel class is not called. As a consequence, the background is not cleared each time. This means that the previously drawn dots would be visible, the background color would not be drawn, and the count value would overwrite itself until it became unreadable.
