Hi Friend,

Try the following code:

class Shape {
int x,y;
void area(){
}
}
class Square extends Shape {
int l=2;
void area() {
System.out.println(l*l);
}
}
class Rectangle extends Shape {
int l=2,b=3;
void area() {
System.out.println(l*b);
}
}
class Circle extends Shape {
int radius=5;
void area() {
System.out.println(3.14*radius*radius);
}
}
class Polymorphism {
public static void main(String[] args) {
Shape shapes[] = new Shape[4];
shapes[0]= new Shape();
shapes[1] = new Square();
shapes[2] = new Rectangle();
shapes[3] = new Circle();

for(int i=0;i<shapes.length;i++) {
shapes[i].area();
}
}
}
