why this java code is showing a runtime error.

import java.util.Scanner;
public class ATM{
    public static void main(String[] args){
        Scanner ip = new Scanner(System.in);
        double bal = ip.nextDouble();
        int amt = ip.nextInt();
        if((bal>=0&&bal<=2000)&&(amt>0&&amt<=2000)){
            if((bal>amt+0.5)&&(amt%5==0)){
                bal-=(amt+0.5);
                System.out.println(bal);}
        else System.out.println(bal);
        }
    }
}

RESULT : RUNTIME ERROR Doubt ; Y is it so? it is working on pc
