Step by step
Solved in 2 steps
- Complete the code for the following program. You are provided with an abstract class called abst. Create a class that will be a child of abst and it will be called usesAbst. Your program will have an int variable called value, and all the appropriate methods, as well 2 constructors. The first constructor will simply set the variable value to 0. The second constructor will set the variable value to equal a passed in parameter. You do not have to comment your code. public abstract class abst{ public abst () { } //Outputs to the screen the message Hello public abstract void sayHello (); //returns the stored int value public abstract int getValue (); //sets the int value to x public abstract void setValue (int x); //Outputs to the screen the message Another method public void output () { System.out.println("Another method"); public String tostring () { return "This is an abstract class"; }Program - Python Make a class.The most important thing is to write a simple class, create TWO different instances, and then be able to do something. For example, create a pizza instance for Suzie, ask her for the toppings from the choices, and store her pizza order. Then create a second pizza instance for Larry, ask for his toppings and store his pizza order. Then print both of their orders back out. You do not need to make your class very complicated. (Shouldn't be the pizza example but something similar)1)Create a complete Java class that can be used to create a Computer object as described below:A Computer has a:- Manufacturer- Disk Size- Manufacturing Date- Number of coresa) Add all instance variables (data encapsulation is expected).b) The class must have getters and setters for all instance variables.c) The class must have two constructors: a no-arg constructor and a constructor thatreceives input parameters for each instance variable.d) Implement a toString() method for your class. 2)Write a Java program TestComputer, which creates three Computer objects with the informationbelow:a) - Manufacturer: Dell- Disk Size: 1189160321024 bytes- Manufacturing Date: April 1, 2020- Number of cores: 2b) - Manufacturer: Apple Inc- Disk Size: 269283712040 bytes- Manufacturing Date: March 31, 2020- Number of cores: 4c) Create your own Object. You can mimic your actual personal computer or use a no-argsconstructor.Print the three objects using toString() method to show all data fields
- Java- Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables.Define a constructor to display a message?A Java-supplied default (a.k.a. a no-argument, or no-args) constructor (i.e., a constructor that takes no parameters and essentially does nothing) is automatically generated by Java for a class, provided that no other constructor is defined for the class. * True False
- Write a graphical application that contains a class named RV whose objects are the recreational vehicle designed and digitized as described in Knowledge Exercises 20 and 21 (you can design your version as well. Simple car shape is will be appreciated. The class’s private data members should be the vehicle’s body color and (x, y) location. a) Give the UML diagram for the class. It should include a three-parameter constructor, a toString method, a method to input the values of all of an object’s data members, and a show method to draw the RV at its current (x, y) location. b) Progressively implement and test the RV class by adding a method and verifying it before adding the next method. A good order to add the methods to the class is the three-parameter constructor, followed by the toString method, the show method, and finally the inputmethod. The client code should create an RV object using the three-parameter constructor to test all of the methods as they are progressively added to the…!! E! 4 2 You are in process of writing a class definition for the class Book. It has three data attributes: book title, book author, and book publisher. The data attributes should be private. In Python, write an initializer method that will be part of your class definition. The attributes will be initialized with parameters that are passed to the method from the main program. Note: You do not need to write the entire class definition, only the initializer method lili lilıCreate a Ferret class with properties name and weight passed to the constructor.
- a.)Write a Java statement that increments the value of count by 1. b.) Write a Java statement that outputs the value of count. C.) Write the 6 definition of constructors and the methods of the class MyClass as described in its definition.Write C# code to perform the following: Create TrainingStudent class & implement variables, make sure about traiffPoint input range using TraiffPoint property. Create two constructors as follows: [both constructors should increment the class variable appropriately] The first is a default constructor that has no parameters and sets the instance variables to either "not known" for the strings, 20 for the integer. The second takes 3 parameters, one for each of the instance variables. Create ShortTraining & LongTraining classes (extending TrainingStudent) & implement variables month & year & make sure about Month & Year range inside property. After Implementation Verify & validate your Logic using following main Code. TrainingStudent t = new TrainingStudent(); t.Print(); // Not Known – Not Known – 20TP TrainingStudent t2 = new TrainingStudent(“12”, “akram”,150); t2.Print(); // 12 –…Write a code in Java programming You are working in a game company that is developing a new RPG game. One of the core features of the game is the ability to create and manage different types of characters, such as warriors, mages, and archers. However, your colleague, who was previously working on the implementation of the CharacterManager class, has been laid off due to excessive absences. You have been assigned to take over the project and complete the implementation of the class based on the design specifications outlined below: Given the following main method: public static void main(String[] args) { CharacterManager manager = CharacterManager.getInstance(); manager.createCharacter(CharacterType.WARRIOR).attack(); manager.createCharacter(CharacterType.MAGE).attack(); manager.createCharacter(CharacterType.ARCHER).attack(); } Your output should be: Warrior is attacking Mage is attacking Archer is attacking Note that you should not change the method signature.
