Java code:

import java.util.Random;

public class Main {
    public static void main(String[] args) {
        // object to call random numbers
        Random random = new Random();
        int num = 0; // to store the number
        do {
            num = random.nextInt(10);
            System.out.println(num * num); // printing the output
        } while (num != 0); // terminating condition

    }
}
