What is wrong in my code,i want output of area of circle in fraction

Question

import java.util.Scanner;

abstract class Shape {
int width;
abstract void area();
}

class Circle extends Shape
{
double pi = 3.14, ar;
public Circle(int w){
this.width = w;
}
@Override
public void area()
{
//super.area();
ar = pi * this.width * this.width;
System.out.println("Area of circle:"+ar);
}
}
class Square extends Shape
{
int ar;

public Square(int w){
this.width = w;
}
@Override
public void area()
{
//super.area ();
ar = this.width * this.width;
System.out.println("Area of Square :"+ar);
}
}

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

Your code is correct and working without error in sololearn u can to give all inputs at a time

Answer 2
