Problem with code : Shapes in Java lesson

I can resolve the problem. I got the output expected but it says that the hidden test case 3 is not the same as my result. Help

I fixed it. For some reason just writing: this.width * Math.PI * this.width Instead of : this.width*this.width * Math.PI And adding @Override before the area method fixed it lol

import java.util.Scanner; abstract class Shape { int width; abstract void area(); } //your code goes here public class Program { public static void main(String[ ] args) { Scanner sc = new Scanner(System.in); int x = sc.nextInt();//almacena datos para Square int y = sc.nextInt();// almacena datos para circle Square a = new Square(x); //debe generar el area del cuadrado (de la anchura) Circle b = new Circle(y);//area del circulo dado a.area(); b.area(); } } public class Square extends Shape{ public Square(int width){ this.width=width; } @Override public void area(){ System.out.println(this.width = this.width* this.width); } } public class Circle extends Shape{ public Circle(int a){ this.width=a; } @Override public void area(){ System.out.println(Math.PI*(double) width*width); } }

System.out.println(Math.PI* (double)width*width // * Math.PI // not at the end );
