- JAVA CLASS AND OBJECT JAVA JAVA JAVA Write a java program/code of the given problems below: abstract class Animal { // abstract methods abstract void move(); abstract void eat(); // concrete method void label() { System.out.println("Animal's data:"); } } 1.) Modify the abstraction example code above by adding another class “TestCarabao” with the necessary methods “label, move, and eat”. 2.) Write a program that creates a car object, and displays the year and name with one method “speed”. Example output: Year: 2021 Model: Toyota Speed: 200km/h 3.) Write the main class of the given class Animal below that set the number of legs to “4” and display (get) the number of legs. class Animal { private int numberOfLegs; public void setNumberOfLegs(int numberOfLegs) { this.numberOfLegs = numberOfLegs; } public int getNumberOfLegs() { return numberOfLegs; } }Using any application of your choice, write a Java program that meets the following requirements: It has an abstract class that contains a student number; Include get() and set() methods for the abstract class where the student number is set/get; Create three child classes, for firstYear, secondYear and thirdYear. Each class must display a distinct announcement for first years, second years and third years.INTRO JAVA Problem 1 Implement a superclass Person. Make two classes, Student and Instructor, that inherits from Person. A person has a name and a year of birth. A student has a major, and an instructor has a salary. Write the class declarations, the constructors, and the methods toString & equals for all classes. Supply a test program for these classes and methods. Problem 2 Make a class Employee with a name and salary. Make a class Manager that inherits from Employee. Add an instance variable, named department, of type String. Make a class Executive inherit from Manager. Implement toString and equals methods for all classes; supply a test program that tests these classes and methods toString() method should print all the properties of the class; as Name and DOB is same for both student and instructor, you can implement it in the superclass "Person" Problem 1 Create 3 students Student1 : Name James, DOB: 01/01/2000, Major: English Student2: Name Jane, DOB:…
- Write the code below for the Computer class. The Computer class must be an abstract class, and have the following methods and attributes: • a public string called HostName • a private int called MemorySize • a public abstract method called shutdown that takes no arguments and returns nothing • a public abstract method called runProgram that takes a String for the name of the program and returns a boolean. • Also include getter/setter methods for the attributesSOLVE IN C# Define a class Shape with an abstract method CalculateArea(). Define two additional classes for a triangle and a rectangle with fields width and height (values being set through appropriate constructors), which implement CalculateArea(). This method has to return the areas of the rectangle (height*width) and the triangle (height*width/2). Define another class for a circle with an appropriate constructor, which initializes the two fields (height and width) with the same value (the radius) and implement the abstract method for calculating the area. Create an array of different shapes and calculate the area of each shape in another array. helpSubject: Java Programming Question#1: Define an abstract class LivingBeing. Define abstract methods breath, sleep, eats. Define Subclasses Animal and Plants. Override the base methods and call them polymorphically.
- use C++ programming language. Design and implement a class dayType that implements the day of the week in a program. The class dayType should store the day, such as Sun for Sunday. The program should be able to perform the following operations on an object of type dayType: Set the day. Print the day. Return the day. Return the next day. Return the previous day. Calculate and return the day by adding certain days to the current day. For example, if the current day is Monday and we add 4 days, the day to be returned is Friday. Similarly, if today is Tuesday and we add 13 days, the day to be returned is Monday. Add the appropriate constructors.Java Programming Object-Oriented Programming In an abstract class, write a factory method for creating a category of object of your choice (aside from furniture). Also, write the class representing that category.b) Write the child classes that are necessary to create 3 different types of objects that belong to that categoryWrite a program in java Write a class Car that contains the followings attributes: The name of Car The direction of Car (E, W, N, and S) The position of Car (from imaginary zero point) The class has the following members A constructor to initialize the instance variables Turn function to change the direction of Car to one step right side (e.g. if the direction is to E, it should be changed to S and so on. Overload the Turn function to change the direction to any side directly. It should accept the direction as parameter. Move function to change the position of Car away from zero point. It should accept the distance as parameter.
