Java Program To Add Two Number

Here's a simple Java program to add two numbers entered by the user:

import java.util.Scanner;

public class AddTwoNumbers {
    public static void main(String[] args) {
        // Create a Scanner object to read input from the user
        Scanner scanner = new Scanner(System.in);

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

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

        // Close the Scanner object to prevent resource leak
        scanner.close();

        // Add the two numbers
        double sum = num1 + num2;

        // Display the result
        System.out.println("The sum of " + num1 + " and " + num2 + " is: " + sum);
    }
}

In this program:

• We use the Scanner class to read input from the user.
• We prompt the user to enter two numbers.
• We read the input numbers using the nextDouble() method of the Scanner class.
• We add the two numbers and store the result in a variable called sum.
• Finally, we display the sum of the two numbers to the user.
