Question

import java.util.Scanner;

abstract class Shape {
int width;
abstract void area();
}
//your code goes here
class Square extends Shape{
public int area2;
public Square(int x)
{
width=x;
}
public void area()
{
area2=width*width;
System.out.println(area2);
}
}

class Circle extends Shape{
public double area1;
public Circle(int y)
{
width=y;
}
public void area()
{
area1=Math.PI*width;
System.out.println(area1);
}
}
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();
}
}

Answer 1

The formula for the area of the circle is not correct.

Answer 2

In the circle class, it should be: MathPI*width*width

Answer 3

Thank you so much. I finished it

Answer 4

Why is it still wrong 😭
