Java Exercise 3. Movable PointA. Write the classes as shown in the following class diagram. Movable is an interface and MovablePoint implements it. ‘~’ means package access but you can just make it public. (pic1.png) B. Now add the class MovableCircle which also implements the interface Movable and is composed of a MovablePoint. Add a tester that allows the user to enter the radius and center of a MovableCircle. After that ask the user if they want (yes/no) to move the circle and how they want to move it (up, down, left, right). Everytime the circle is moved, you should output its changed position. If the user says “no” the program ends. (pic2.png)

Create an interface Wheel with methods setWheels (int c) and getWheels () and a class Vehicle with abstract methods getColor () and getBrand (). Now, create a concrete class Taxi with additional method setDriver (String name) that inherits both Wheel and Vehicle. (Note: Concrete classes don’t have any abstract method)
Write a class named Employee which implements Comparable Interface with name and salary as data fields Add a constructor with argument name and salary. Add getter and Setter for name and salary. Add CompareTo() method for the data Salary. Write a class named Manager which inherits the Employee class. Add an instance variable, named department, of type String. Add a constructor in the subclass class with arguments name, salary, department and a toString() method that prints the manager’s name, department, and salary [Hint: Add a toString( ) method in the super class as well] Create 3 objects of Manager with following arguments 1. (Zayed, 500), 2. ( Ahmed, 700) 3. ( Faisal, 600) Add the above 3 objects into an ArrayLIst object and Sort by Salary and Display.

*using java* Create a class AnimalCreate a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal(String name) //constructor public void makesSound()with the implementation printing out a generic animal sound. Next, override (add) the makesSound()method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don’t make sounds!)Note, you’ll also need a constructor in each of your subclasses which calls super(name) to initialize the common ‘name’ member of Animal. --- Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. ( you should observe the implementation of the makeSound() method called will be: cat -> from Cat class, dog-> from Dog class,…
In the following there are two classes, Employee and Manager. Manager is a subclass of Employee. The implementation of Employee class is given (Note: no getter methods are provided, so you are not able to access instance variables through getter methods in the subclass). The skeleton of the Manager class definition is given. Complete the constructor method, and the toString method for the subclass (see the details below). public class Employee { private String name; private double salary; // Make an employee with a given name and salary. public Employee(String aName, double aSalary) { name = aName; salary = aSalary; } // Provide a string description of an employee. public String toString() { return "Name: " + name + "\tSalary: " + salary; } } public class Manager extends Employee { private String department; // Make a manager with a given name, salary, and department. public Manager(String name, double salary, String department) { // put your code below } // Provide a string…

This question involves the design of a class that will be used to produce practice problems. The following StudyPracticeinterface represents practice problems that can be used to study some subject. public interface StudyPractice. { /**Returns the current practive problem */ String getProblem(); /** Changes to the next practice problem */ void nextProblem(); } The MultPractice class is a StudyPracticethat produces multiplication practice problems. A MultPractice object is constructed with two integer values: first integer and initial second integer. The first integer is a value that remains constant and is used as the first integer in every practice problem. The initial second integer is used as the starting value for the second integer in the practice problems. This second value is incremented for each additional practice problem that is produced by the class. For example, a MultPractice object created with the call new MultPractice (7, 3)would be used to create the practice…
