URI online judge - 1017 - wrong answer (60%)

Question

Input
The input file contains two integers. The first one is the spent time in the trip (in hours). The second one is the average speed during the trip (in Km/h).

Output
Print how many liters would be needed to do this trip, with three digits after the decimal point.

Problem number 1017 so I take two integer in input file and three digit after decimal point in output file but getting wrong answer (60%). Here is the code:

import java.util.Scanner;
public class Main{
    public static void main( String args []){
        Scanner sc=new Scanner (System.in);
        int x,y;
        x=sc.nextInt();
        y=sc.nextInt();
        double z=(x*y)/12;
        System.out.printf("%.3f\n",z);
    }
}

What is the 60% wrong answer?

You're doing integer division, then converting the result to a double, instead of the other way around. — Dawood ibn Kareem, Jul 20 '18 at 09:57
Replace the `12` with `12.0` to do double division. Alternatively you can cast one of the inputs to `double`. — QBrute, Jul 20 '18 at 10:00

What are the constraints?
If the integers are large, maybe you should use long instead of int.
If they are larger than that, use BigInteger or BigDecimal.
