I need a java code and use eclipse

Study the following program TestRectangle.java carefully. Create a class called Rectangle. Rectangle has three double instance variables: height, width and area. When running TestRectangle.jave and Rectangle.java, it will produce the output at the end of this question.

TestRectangle.java:

1. public class TestRectangle {

   public static void main(String[] args) {

   System.out.println("**********************************");

   Rectangle r1 = new Rectangle();

   System.out.println("Dimension of R1: " + r1.getWidth() + " X " + r1.getHeight());

   System.out.println("Area of R1: " + r1.getArea());

   System.out.println("Is R1 a square? " + r1.isSquare());

   System.out.println("**********************************");

   Rectangle r2 = new Rectangle();

   r2.setHeight(2.0);

   r2.setWidth(3.0);

   System.out.println("Dimension of R2: " + r2.getWidth() + " X " + r2.getHeight());

   System.out.println("Area of R2: " + r2.getArea());

   System.out.println("Is R2 a square? " + r2.isSquare());

   System.out.println("**********************************");

   Rectangle r3 = new Rectangle(4.0, 5.0);

   System.out.println("Dimension of R3: " + r3.getWidth() + " X " + r3.getHeight());

   System.out.println("Area of R3: " + r3.getArea());

   System.out.println("Is R3 a square? " + r3.isSquare());

   System.out.println("~~ Done! ~~");

   }

   }

   Output:

   **********************************

   Dimension of R1: 1.0 X 1.0

   Area of R1: 1.0

   Is R1 a square? true

   **********************************

   Dimension of R2: 3.0 X 2.0

   Area of R2: 6.0

   Is R2 a square? false

   **********************************

   Dimension of R3: 5.0 X 4.0

   Area of R3: 20.0

   Is R3 a square? false

   ~~ Done! ~~
