Question

How to generate N pairs of random digits in Java

Answer 1

import java.util.Random;

public class Main {
    // Method to generate and print N random digit pairs
    public static void generateRandomPairs(int N) {
        Random rand = new Random();
        System.out.println("Random pairs of digits:");
        for (int i = 0; i < N; i++) {
            int firstDigit = rand.nextInt(10);  // Random digit between 0 and 9
            int secondDigit = rand.nextInt(10); // Random digit between 0 and 9
            System.out.printf("(%d, %d)%n", firstDigit, secondDigit);
        }
    }

    public static void main(String[] args) {
        int N = 15;
        generateRandomPairs(N);
    }
}
