Question 1 The Singleton pattern is a creator design pattern: Because it creates other design patterns Because it defines a way to implement creating objects Because you create it whenever you want Question 2 Private visibility for class members and methods is used: to keep the code secure to enable encapsulation of object functionality to eliminate low cohesion

Computer Science The project statement o Create a Java Project as follows:  Add at least three classes  Should apply OOP concepts e.g. Inheritance and Polymorphism Implements at least one interface and extends one Abstract class Create at least 2 objects for each class  Call at least 2 methods from each class o Students should submit a Word document describing their application project.
UML Class Diagram Modeling representation of messages and mailboxes in the email system that you use. Modeling task: object classes that might be used in the system implementation to represent a mailbox and an e-mail message. Include attributes, methods and relationships.
Objects enable the design practice of --------------—although they may know how to communicate with one another across well- defined interfaces, they normally are not allowed to know how other objects are implemented.
—————— makes it easy to construct a new kind of object. The new class (referred to as the subclass) begins with the features of an existing class (referred to as the superclass), potentially modifying and adding its own unique qualities.
Use of interfaces has many benefits. The creation of objects of a certain class seems to be the simplest solution.
Sequence diagram Create a UML sequence diagram that will show your clients how the system’s classes will interact when customers are buying their flight tickets on the booking website. How to create your assignment Review the code responsible for adding a new item. Make a sequence diagram that captures the interactions of objects in the app when a new item is added. Your sequence diagram should contain the following classes: AddItemActivity ItemList Dimensions Item And contain calls of the following methods: onCreate() loadItems() saveItem() Dimensions constructor Item constructor addItem() saveItems() Lastly, the activation of AddItemActivity should start with the call to “onCreate()”
Case-Based Critical Thinking Questions Case 13-5 Steve has created a custom object. He wants to use a template for all the properties and methods associated with the object's class To add a method to a prototype, Steve should apply the command O objName.prototype function method Oohnstance prototype method function objClass prototype method function ObName prototype method function
Library Information System Design and Testing Library Item Class Design and TestingDesign a class that holds the Library Item Information, with item name, author, publisher. Write appropriate accessor and mutator methods. Also, write a tester program(Console and GUI Program) that creates three instances/objects of the Library Items class. Extending Library Item Class Library and Book Classes: Extend the Library Item class in (1) with a Book class with data attributes for a book’s title, author, publisher and an additional attributes as number of pages, and a Boolean data attribute indicating whether there is both hard copy as well as eBook version of the book. Demonstrate Book Class in a Tester Program (Console and GUI Program) with an object of Book class.
When designing a class that implements Comparable, what design patterns or principles should be considered to promote code reusability and maintainability?
Instructions JAVA LANGUAGE The Factory Method pattern provides an interface for creating objects in a superclass but allows subclasses to alter the type of objects to be created. Use NetBeans to create a Java program that implements this design pattern. Name your project TestFactory. Create an abstract superclass named Laptop. Any subclass of an abstract class must either implement all of the abstract methods in the superclass or be declared abstract itself. Copy the code below. abstract class Laptop { public abstract int getRAM(); public abstract int getSSD(); public abstract String getCPU(); public String toString() { return "RAM="+this.getRAM()+"GB, SSD="+this.getSSD()+", CPU="+this.getCPU(); } } Create a subclass named Minimum that extends your superclass. In this class, declare three (3) private variables with the following names and data types: ram (int) ssd (int) cpu (String) Copy the code below for the constructor of your Minimum class. This constructor has…

1. IntroductionCCCS 121Object Oriented Programming language Group Course ProjectAn object-based application is an application that involves objects created out of classes. These objects interact with each other to fulfill certain functionalities.The focus of this project is to develop an application written in java which involves the use of object-oriented programming. This project is a group project. As a student you will be given a chance to come up with an idea for your project. However, the project must satisfy the requirements given in this document.This document shall be used as a set of guidelines. You are allowed to make necessary additions and/or changes to the requirements with prior approval from your instructor.2. RequirementsPropose and implement an application, that contributes to solving a real-life problem. Your application should include at least the following:2.1 Classes3 to 4 classes each one of them should have:A. B. C.A number of private and public attributes. The…
