Hints

Integer division by zero throws ArithmeticException (double division gives Infinity instead).

Solution explanation

Note the difference: 5 / 0 throws, but 5.0 / 0 is Infinity.

Show solution

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        for (int i = 0; i < n; i++) {
            int a = sc.nextInt(), b = sc.nextInt();
            try {
                System.out.println(a / b);
            } catch (ArithmeticException e) {
                System.out.println("cannot divide by zero");
            }
        }
    }
}
