Addition of two numbers in java

In this post we will go through the process of adding two numbers in Java.

Problem :

here is the simple example –

Input :

Enter the first number: 10
Enter the second number: 5

Output :

The sum of the two numbers is: 15.

Explanation :

In this example, the user entered 10 as the first number and 5 as the second number. The program then calculated the sum (10 + 5 = 15) and displayed the result. The actual output will depend on the specific numbers you enter during the program execution.

Solution :

Algorithm for addition of two numbers:

  1.  Declare and initialize two variables you want to add.
  2.  Declare another variable to store the sum of numbers.
  3.  use the “+” operator to add the numbers.
  4.  Display the result.

Approach 1 :  Sum of Two Numbers

//Addition of two numbers
class SumofNumbers{
public static void main(String[]args){
int num1=40;
int num2=20;
int sum=num1+num2;
System.out.println("Addition of two numbers is :"+sum);

Addition of two numbers is : 60

Approach 2 : Using Scanner Class (User Input)

import java.util.Scanner;
class SumofNumbers2{
public static void main(String[]args){
Scanner sc=new Scanner(;
System.out.println("Enter the first number");
int n1 =sc.nextInt();
System.out.println("Enter the second number");
int n2 =sc.nextInt();
int sum = n1+n2;
System.out.println("the sum of these two numbers is :"+sum);

Output :

Enter the first number: 26 
Enter the second number: 34
the sum of these two numbers is : 60
Basic Java Program :
