The software I use is Eclipse, please teach me how to write it on Eclipse.

1. 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-argument constructor (default-constructor) that creates a default constructor. 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 getPerimeter0 that returns the perimeter Write a test program that creates two Rectangle objects- one with width 4 and height 40, and the other with width 3.5 and height 35.9. Display the width, height, area, and perimeter of each rectangle in this order
