Question

In java Define an interface called Shape with two methods that calculate perimeter and area. Write a program to create the MyRectangle class that implements the Shape interface and contains:

The double data fields width and height with get and set methods.

A no-arg constructor that creates a default rectangle with 1 for both width and height.

A constructor that creates a rectangle with the specified width, and height.

A method getArea() that returns the area of the rectangle.

A method getPerimeter() that returns the perimeter of the rectangle.

Explanation / Answer

Shape.java

public interface Shape {

public double calculatePerimiter();
public double calculateArea();
}

MyRectangle.java

public class MyRectangle implements Shape{

private double width;
private double height;
  
public MyRectangle() {
this(1,1);
}
  
public MyRectangle(double width, double height)
{
this.width = width;
this.height = height;
}
  
public double calculatePerimiter() {
return 2*(width + height);
}

@Override
public double calculateArea() {
return width*height;
}

}
