How do i fix this illegal start of expression

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

Remove the extra multiplication operator:

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 2

why are you using * after width ??
area1=Math.PI*width*;

//area1=Math.PI*width;
