I have to found area of shape ...it shows can not find symbol... What's wrong with this code??
import java.util.Scanner; abstract class Shape { int width; abstract void area(); } //your code goes here public class Square extends Shape { Square (int x){ this .width = x; } public void area (){ println ("sarea"+(this.width * this.width )); } } public class Circle extends Shape { Circle (int x){ this .width = x; } public void area (){ println ("carea"+(Math.PI * this.width * this.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(); } }
