add 2 numbers java program
Reading Time: 7 minutes

Introduction:

The Java program you provided is a simple console-based application that adds two numbers. It utilizes the Scanner class to take user input for two numbers, performs the addition operation, and then displays the result.

Explanation:

  1. Import Statements:

The program starts by importing the Scanner class from the java.util package. This class is used to take user input from the console.

  1. Class Declaration:

The program defines a class named AddTwoNumbers. Java programs typically consist of one or more classes, and the main method within the class serves as the entry point for execution.

  1. Main Method:

The main method is the starting point of the program. It is where the execution begins.

  1. Scanner Initialization:

An instance of the Scanner class is created to read input from the user.

  1. User Input:

The program prompts the user to enter the first number, reads the input as a double, and stores it in the variable num1. The same process is repeated for the second number.

  1. Addition Operation:

The two numbers entered by the user are added, and the result is stored in the variable sum.

  1. Output:

The program prints the result, indicating the sum of the two numbers.

  1. Scanner Closing:

The Scanner is closed to release system resources and avoid potential resource leaks.

Algorithm:

  1. Import the Scanner class.
  2. Define the class AddTwoNumbers.
  3. Declare the main
  4. Create a Scanner instance for user input.
  5. Prompt the user to enter the first number and read it.
  6. Prompt the user to enter the second number and read it.
  7. Add the two numbers and store the result in the sum
  8. Print the result using a formatted message.
  9. Close the Scanner to release resources.

Code :

    
     import java.util.Scanner;
public class AddTwoNumbers {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("Enter the first number: ");
        double num1 = scanner.nextDouble();
        System.out.print("Enter the second number: ");
        double num2 = scanner.nextDouble();
        double sum = num1 + num2;
        System.out.println("The sum of " + num1 + " and " + num2 + " is: " + sum);
        // Close the scanner to avoid resource leak
        scanner.close();
    }
}

    
   

Input :

    
     Enter the first number: 65
Enter the second number: 68
    
   

Output :

    
     The sum of 65.0 and 68.0 is: 133.0
    
   

This program takes two numbers as input from the user, adds them, and then prints the result.
