SECTION 1: The Screen Saver
Design, code, and test an application that simulates a screensaver. The application should randomly draw lines using method drawLine of class Graphics. After drawing 100 lines, the application should clear the screen and start drawing lines again. To allow the program to draw continuously, place a call to repaint as the last line in method paintComponent. There could be problems getting this application to function perfectly on any particular computer system. That would be a good topic for the discussion threads; how well the screen saver works on your computer.
