Lab 2: Rectangle
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 set to 0.0 for both width and height. There is a no-arg constructor that creates a default rectangle. There is also a constructor that creates a rectangle with the specified width and height. Additionally, there is a method named getArea() that returns the area of this rectangle, and a method named getPerimeter() that returns the perimeter. Create a driver class (main class) and create three Rectangle objects.
