public class Findareas{ public static void main (String []agrs){ Figure f= new Figure(10 , 10); Rectangle r= new Rectangle(9 , 5); Figure figref; figref=f; System.out.println("Area is :"+figref.area()); figref=r; System.out.println("Area is :"+figref.area()); } } class Figure{ double dim1; double dim2; Figure(double a , double b) { dim1=a; dim2=b; } Double area() { System.out.println("Inside area for figure."); return(dim1*dim2); } } class Rectangle extends Figure { Rectangle(double a, double b) { super(a ,b); } Double area() { System.out.println("Inside area for rectangle."); return(dim1*dim2); } } 以上代码运行输出结果为： Inside area for figure. Area is :100.0 Inside area for rectangle. Area is :45.0
