One or two negative numbers

 Objetive

Write a java program to prompt the user for two numbers and determine whether both are negative, only one is negative, or neither is negative.

 Example Code

import java.util.Scanner;

public class Program {
    // Main entry point of the program
    public static void main(String[] args) {
        // Create a scanner to read user input
        Scanner scanner = new Scanner(System.in);

        // Declare variables to store the two numbers entered by the user
        int num1, num2;

        // Prompt the user to enter the first number
        System.out.print("Enter the first number: ");
        num1 = scanner.nextInt();

        // Prompt the user to enter the second number
        System.out.print("Enter the second number: ");
        num2 = scanner.nextInt();

        // Check the conditions for both numbers being negative, one negative, or neither
        if (num1 < 0 && num2 < 0) {
            // If both numbers are negative, display this message
            System.out.println("Both numbers are negative.");
        } else if (num1 < 0 || num2 < 0) {
            // If only one of the numbers is negative, display this message
            System.out.println("One number is negative.");
        } else {
            // If neither of the numbers is negative, display this message
            System.out.println("Neither of the numbers is negative.");
        }
    }
}
