java pta 6-1设计一个矩形类Rectangle

    import java.util.Scanner;


    public class Rectangle{
        static double width=1;
        static double heigth=1;

        public Rectangle(){ }
        public Rectangle(double w,double h){
            width=w;
            heigth=h;
        }

        double getArea(){
            return width*heigth;
        }

        double getperimeter(){
            return 2*(width+heigth);
        }

        public static void main(String[] args) {
            Scanner sc = new Scanner(System.in);

            double w = sc.nextDouble();
            double h = sc.nextDouble();

            Rectangle  input= new Rectangle();

Rectangle myRectangle=new Rectangle(w,h);
            System.out.println(input.getArea());
            System.out.println(input.getperimeter());

        }

    }
