Expert Solution & Answer
Chapter 4, Problem 1RQ
Explanation of Solution
Binary Principle:
- Binary principle refers to those things which can be thought of as existing in any one of the two states.
- These states are logic 1 and logic 0.
- Basically, logic 1 can also be represented as “ON” or “True” or “YES”.
- Similarly, logic 0 can also be represented as “OFF” or “False” or “NO”.
- The key to the speed and accuracy with which information can be processed is that there are only two states, each of which is distinctly different.
- Therefore, for any combination of input, the output will be either logic 1 or logic 0.

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. What design pattern can be used to implement the user interface? Explain your answer using a class diagram for the entire system. b. Draw a UML sequence diagram to show the behavioral view of the Personal Address Book program, demonstrating what happens when a user enters new contact information.arrow_forwardA system comprises three components: A, B, and C.
