In Idea my code works, but here is a runtime error:

import java.util.Scanner;

public class MathematiciansAndBerries {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        byte a1 = scanner.nextByte();
        byte b1 = scanner.nextByte();
        byte a2 = scanner.nextByte();
        byte b2 = scanner.nextByte();
        byte a3 = scanner.nextByte();
        byte b3 = scanner.nextByte();

        System.out.println((a1 - a3) + " " + (b1 - b2));
    }
}

Help pls, why runtime error occurs?

Changed byte to int and now it works ok here. Idiotic. I don't think a mathematician can bring more than 127 kg))

"0 <= ai, bi <= 10,000"
Sure, do not read condition is idiotic.
