Shapes lab for Java course

Question

The code doesn't work. What do I need to change?
------------------
import java.util.Scanner;
import java.math.BigDecimal;
abstract class Shapes {
BigDecimal width;
abstract void area();
}
//your code goes here
class Square extends Shapes{
BigDecimal width;
public Square(BigDecimal x) {
this.width = x;
}
public void area(){
System.out.println(this.width.multiply(this.width));
}
}
class Circle extends Shapes{
BigDecimal width;
public Circle(BigDecimal y){
this.width = y;
}
public void area(){
System.out.println(this.width.multiply(this.width.multiply(new BigDecimal(Math.PI))).doubleValue());
}
}
public class Program {
public static void main(String[ ] args) throws Exception {
Scanner sc = new Scanner(System.in);
int x = sc.nextInt();
int y = sc.nextInt();
if (x <= 0 && x <= Integer.MAX_VALUE) {
throw new Exception();
}
else {
BigDecimal x_float = new BigDecimal(x);
Square a = new Square(x_float);
a.area();
}
if (y <= 0 && y <= Integer.MAX_VALUE) {
throw new Exception();
}
else {
BigDecimal y_float = new BigDecimal(y);
Circle b = new Circle(y_float);
b.area();
}
if (x <= 0 && y <= 0) {
throw new Exception();
}
}
}

Answer 1

Your code is woRkiNg properly but i doing mistakes after running give two input your code calculating correct check again.

Answer 2

Could you please write in English, ♨️♨️?

Answer 3

Shyamal Chandra you can copy text and paste on google translator.

Answer 4

import java.util.Scanner;
abstract class Shape {
int width;
abstract void area();
}
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*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();
}
}
