- create a "UML Class Diagram" with the files below. I attempted to mae it myself, but I dont know if its right or not. Application.java: package com.mycompany.csc325_abstractfactorydesignpattern; import java.awt.print.Paper; /** * * @author MoaathAlrajab */ public class Application { //Application to describe a publication privateWrittenPiecepaper ; privateIllustrationdrawing; publicApplication(WritingFactoryfactory) { drawing = factory.drawSomething(); paper = factory.writeSomething(); } publicvoidrevealContent(){ paper.typeOfPiece(); drawing.depictInfo(); } }Book.java: package com.mycompany.csc325_abstractfactorydesignpattern; /** * * @author MoaathAlrajab */ public class Book implements WrittenPiece { @Override publicvoidtypeOfPiece() { System.out.println("Book is a written piece"); } }Charts.java: package…Every JavaScript object has a constructor function that acts as a template for all the properties and methods associated with the object’s class, and a prototype, which can be thought of as a machine to instantiate objects. Select one: True FalseThis way, any class that implements the Visible interface can define its own behavior for making an object visible or invisible based on its specific requirements.Create a Priority Java interface with two methods: setPriority and getPriority. The interface should define a method for assigning numerical priority to a group of objects. Create a class named Task that represents a task (such as one on a to-do list) that implements the Priority interface. Make a driver class to test certain Task objects.
- Subject: Java Programming Question#3: Define an interface Frame with methods paint, redraw and fields width, height, title. Provide implementation of interface with classes Window, Dialog. Override the base methods and call them polymorphically.Why is it necessary to devote more time and effort into Java programming (and object-oriented programming in general) to avoid having classes that are tied together when they do not need to be? Which three factors are more significant?Define a Java class namely Customer containing: Instance variables: ⁃ id. A private static instance variable of type integer initialized to 0 (id=0). ⁃ name: A private instance variable of type string. ⁃ discount: A private instance variable of type integer initialized to 10 (discount=10). Methods: ⁃ A parameterized constructor: a constructor method to initialize the name and the discount instantiated objects, the variable id incremented automatically (id=id+ 1) in each instantiate of an object Customer. ⁃ setName(xxx): acts as the set method for the attribute name ⁃ setDiscount(xxx): acts as the set method for the attribute discount (0<= discount<=100). ⁃ getld: acts as the get method for the attribute id ⁃ getName(): acts as the get method for the attribute name ⁃ getDiscount (): acts as the get method for the attribute discount ⁃ toString(): returns the attributes id, name, and discount (with using the getter methods only) in the following format: id name:…
- In Java Use a given class API to create objects and call static and non-static methods of that class.Run the following java code of an Observer Pattern design in Object Oriented Design programming; in Netbeans. Provide screenshots as proof that it runs correctly. Draw a UML class diagram to model the program Java Code: //include the required packageimport java.io.*;import java.util.*;//create a main classpublic class experiment{ //definition of the main function public static void main(String args[]) { //create the object of the Scanner class Scanner in=new Scanner(System.in); //declare the required variables and arrays int time[]=new int[10]; float weight[]=new float[10]; String get; char ch; int i=0; //start of do while loop do { //try block…This way, any class that implements the Visible interface can define its own behavior for making an object visible or invisible based on its specific requirements.Create the Priority Java interface, which has the methods setPriority and getPriority. A method for determining numerical priority among a group of objects should be defined by the interface. Create and implement a class named Task that represents a task that implements the Priority interface, such as one that is on a to-do list. To test some Task objects, construct a driver class.
- Draw a State Chart Diagram describing the interaction protocol of MyTimeSheet. Here is a specification for a class MyTimeSheet. The operations are all public. MyTimeSheet(); // constructor // postcondition: checkHours() is 0 void addHours (int hours, int minutes); // precondition: hours >=0, 0<= minutes <=60, hours+minutes >0 // postcondition: checkHours() > 0 float checkHours(); void issuePaycheck(); // postcondition: checkHours() is 0In Java language, Construct a class; Student with the following fields: Lastname. Firstname,and ID number. Instantiate the class three times. Illustrate in detail the class and object.Draw the UML diagram for the class and then implement the class. For more details about UML diagrams see the “UMLNotation.pdf” by Y. Daniel Liang, located in LabFiles folder. Discuss: Should the class Square have a main method? Use lab_02 as the name of this Java Application project.
