Question
Using Java Eclipse do the following
Design a class named Rectangle to represent a rectangle. The class contains:
- Two double data fields named width and height that specify the width and height of the rectangle. The default values are 1 for both width and height.
- A no-arg constructor that creates a default rectangle.
- A constructor that creates a rectangle with the specified width and height.
- A method named getArea() that returns the area of this rectangle.
- A method named getPerimeter() that returns the perimeter.
Draw the UML diagram for the class then implement the class. Write a test program that create two Rectangle objects - one with width 4 and height 40, and the other with width 3.5 and height 35.9.
Display the width, heigth, area, and perimeter of each rectangle in this order.

- 3arrow_forwardCreate an application named RecoveringDemo that declares objects of three types: Patient, Upholsterer, and FootballPlayer. Create an interface named IRecoverable that contains a single method named Recover(). Create the classes named Patient, Upholsterer, and FootballPlayer so that each implements IRecoverable. Create each class’s Recover() method to display an appropriate message. For example: The Patient’s Recover() method should display I am getting better. The Upholsterer's Recover() method should display I have new material for the couch. The FootballPlayer's Recover() method should display I picked up the ball after a fumble.arrow_forwardThe class Shapes includes two void methods: calcTriangleArea( ) and calcTrianglePerimeter( ). The calcTriangleArea ( ) method takes two int parameters (base and height), calculates the area of a triangle, and assigns the value to a private instance variable (area). The calcTrianglePerimeter( ) method takes three int parameters (lengthSide1, lengthSide2, and lengthSide3), calculates the perimeter of a triangle, and assigns the value to a private instance variable (perimeter). The Shapes class also includes two getter methods, which return the calculated values. The Shapes class implements the Calculatable interface.Write the Shapes class and the Calculatable interface.arrow_forward
