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:
- 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.
- 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.
- Main Method:
The main method is the starting point of the program. It is where the execution begins.
- Scanner Initialization:
An instance of the Scanner class is created to read input from the user.
- 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.
- Addition Operation:
The two numbers entered by the user are added, and the result is stored in the variable sum.
- Output:
The program prints the result, indicating the sum of the two numbers.
- Scanner Closing:
The Scanner is closed to release system resources and avoid potential resource leaks.
Algorithm:
- Import the Scanner class.
- Define the class AddTwoNumbers.
- Declare the main
- Create a Scanner instance for user input.
- Prompt the user to enter the first number and read it.
- Prompt the user to enter the second number and read it.
- Add the two numbers and store the result in the sum
- Print the result using a formatted message.
- 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.
