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; } }Code is in Java find the error in the following class definition:public class MyClass { private int x; private double y; public void MyClass(int a, double b) { x = a; y = b; } } 1) What is the problem? 2)How will you fix it?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:…
- 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.The following code is in Java: public class Vehicle // Superclass { private double cost; (Other methods . . .) // assume these are given and they’re OK. } // Subclass public class Car extends Vehicle { public Car(double c) { cost = c; } }1) What is the problem with the code?2)How can it be fixed?1.
