   public Shape(String color) {
      this.color = color;
   }
   public String getColor() {
      return color;
   }
   public double getArea() {
      return 0.0;
   }
}
public class Rectangle extends Shape {
   private double width;
   private double height;
   public Rectangle(String color, double width, double height) {
      super(color);
      this.width = width;
      this.height = height;
   }
   public double getWidth() {
      return width;
   }
   public double getHeight() {
      return height;
   }
   public double getArea() {
      return width * height;
   }
}
public class Square extends Rectangle {
   public Square(String color, double side) {
      super(color, side, side);
   }
}
public class Main {
   public static void main(String[] args) {
      Shape s = new Square("blue", 5);
      System.out.println(s.getColor() + " " + s.getArea());
   }
}
