}
class Circle{
System.out.println(Math.PI*width*width);
}

}
//your code goes here

public class Program {
public static void main(String[ ] args) {
Scanner sc = new Scanner(System.in);
int x = sc.nextInt();
int y = sc.nextInt();

Square a = new Square(x);
Circle b = new Circle(y);
a.area();
b.area();
}
}

Titanus Gojira You have not used constructors

Answer 5

import java.util.Scanner;

abstract class Shape {
int width;
abstract void area();
}
//your code goes here
class Square extends Shape {
Square (int x) {
width = x;
}
public void area() {
System.out.println(width*width);

}
}

class Circle extends Shape {
Circle (int y) {
width = y;
}
public void area() {
System.out.println(Math.PI*width*width);

}
}

public class Program {
public static void main(String[ ] args) {
Scanner sc = new Scanner(System.in);
int x = sc.nextInt();
int y = sc.nextInt();

Square a = new Square(x);
Circle b = new Circle(y);
a.area();
b.area();
}
}
