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.

- A Personal Address Book application program allows the user to add, delete, search, save, and load contact information. The program separates the user interface (command-line) and the internal processing subsystem. The internal processing system consists of the following classes: • • Contact Manager (responsible for add and delete operations) Contact Finder (responsible for the search operation) pataManager (responsible for save and load operations) a.
