Someone help me with this

Question

import java.util.Scanner ;
import java.lang.Math.* ;

abstract class Shape {
int width;
abstract void area();
}
//your code goes here
class Square extends Shape{
public static int area(int x){
x*=x;
return x;
}
}

class Circle extends Shape{
public static double area(double y){

return Math.PI * y * y;
}
}
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

Try this way:

import java.util.Scanner;
import java.lang.Math.*;

abstract class Shape {
int width;
abstract void area();
}
//your code goes here
class Square extends Shape{
public Square(int width){
this.width = width;
}

public void area(){
int area = this.width * this.width;
System.out.println(area);
}
}

class Circle extends Shape{
public Circle(int width){
this.width = width;
}

public void area(){
System.out.println((double)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();
}
}
