Create a subclass named Square from the superclass Geometricobject. Create an instance variable named width with initial value 0. Create a no-arg constructor. Create the another constructor, which has one parameter named wid. ASsign the wid to the instance variable named width. Create the getWidth() method, the setWidth() method. Override the getArea() method. Override the getPerimeter() method. Create a test class named Test to create an instance with wid= 6 from Square class. Call the getArea() and getPermeter() methods to print out the area and perimeter of the square with width=6.
