- 2.Write a java program that define a class named smartPhone . It is implemented from interfaces mobile and tablet. Moblie contain methods canCall() and simType(). Tablet contain noOfApps(). Test this class in main.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)Write a Program in Java Create an interface EnhancedShape that extends Shape and also requires a method public double perimeter( ) to be implemented by any class that uses the interface. (Note: Interfaces can inherit other interface just like a class by using extends keyword. Create a class file, an interface ehancedshape extends shape, and an interface shape file).
- USING JAVA Write these: An interface called Shape that has two methods: area and perimeter. A class Rectangle that implements Shape and has a length and a width. A class Circle that implements Shape and has a radius. For each class, write the needed constructors, getters, setters, and a toString method that stringifies the instance variables in a readable format. Supply a test program that instantiates an instance of each class and exercises each method defined for the class.JavaPrograming language is Java. Define a class Person that represents a person. People have a name, an age, anda phone number. Since people always have a name and an age, your class shouldhave a constructor that has those as parameters. Define a toString() method whichdisplays all of the relevant information using a format like this: “Jim Lahey - Age 57- Phone 9025555555”.
- Write a program in java Design a class that holds the following personal data: name, address, age, and phone number.Write appropriate accessor and mutator methods. Demonstrate the class by writing aprogram that creates three instances of it. One instance should hold your information, andthe other two should hold your friends’ or family members’ information.Write a java program Write a class named Employee with name and salary as private data fields. Add a constructor with both parameters. Write a class named Manager which unherits the Employee class. Add an instance variable, named department, of type String and 15 private. Add a constructor in the subclass class and a toString () method that prints the manager's name, department, and salary [Hint: Add a tastanel) method in the super class as well]. Create objects of Manager and Employee dass1. Implement the following classes and interface in Java.• Shape interface which has the following methods:– public double perimeter(); // doesn’t have any parameters, returns the perimeter of the shape.– public double area(); // doesn’t have any parameters, returnsthe area of the shape.– public void info(); // doesn’t have any parameters, prints theperimeter and area of the shape.• Circle class that implements Shape interface and has a constructorthat takes the radius.• Rectangle class that implements the Shape interface and has a constructor that takes the width and height.• Square class that extends the Rectangle class and has a constructorthat takes the edge length.– Square constructor should only call the super constructor withcorrect parameters.– Square constructor should not explicitly implement the Shapeclass, but it should inherit the perimeter, area and info methodsfrom the Rectangle class.2. Create a Test class, and create one Circle, one Rectangle and one Squareobjects.…
- WRITE A JAVA PROGRAMUse the class diagram below to create a Parking Charge class for an object-oriented parking system. Write your code using java. Classes should contain properties and method implementations. N.B. Try to make your code readable.Need help on java homework assignment, It says Create a class Vehicle. A Vehicle has a single instance variable of type String named "vehicleType" that describes the vehicle.
