Chapter 11.5, Problem 19SC
Explanation of Solution
Timer Class:
- Timer class is one of the “javax.swing” packages which is used to generate the sequence of action events at regular time intervals.
- When a person wants to send continuous updates to a component then, “Timer” class is used.
- The actions which are need to be executed must be placed inside “actionPerformed” method which is the method of listener object...

You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels.
