Basic Object Oriented

Create a class called Square as described below:

• Fields: height, width • Methods: public double getHeight() public void setHeight(double h) public double getWidth () public void setWidth (double w) public double getArea ()

Hint: If I take your class and use it following would be the code and the output. Code Output double h, w, a; Square s1 = new Square(); s1.setHeight(3); s1.setWidth(4); h = s1.getHeight(); w = s1.getWidth(); a = s1.getArea(); System.out.println(“Height = ”+ h); System.out.println(“Width = ”+ w); System.out.println(“Area = ”+ a); Height = 3.0 Width = 4.0 Area = 12.0
