Errors in programs

Consider the following Java code snippet:

import java.util.Scanner;

public class Test {

    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        int num1 = input.nextInt();
        int num2 = input.nextInt();
        int result = num1 / num2;
        System.out.println("Result: " + result);
    }
}

Given this code, which of the following errors can occur while scanning input or while writing, compiling, and running simple programs?
