In this tutorial you will learn about the Java Program to Add Two Numbers and its application with practical example.
Java Program to Add Two Numbers
In this tutorial, we will learn to create a Java program that will Add Two Numbers in Java programming.
Prerequisites
Before starting with this tutorial, we assume that you are the best aware of the following Java programming topics:
- Operators in Java Programming.
- Basic Input and Output function in Java Programming.
- Basic Java Programming.
What is addition?
The addition in mathematics is the sum of two numbers. The arithmetic operations are done using the arithmetic operators. These operators are used between two arithmetic operands or between two numbers.
Program to Add Two Numbers:-
In this tutorial, we will create a program that will add the two numbers using an addition operator. We will first take two numbers in input, and then we will add them and store the value in the third variable.
As we all know, the integer, float, or double data types in java. In programming, we can take the input from the user in numbers format. In today’s program, we will take input in number format. Secondly, we will add the number with the help of a small program. The numbers are the most useful terminology in any programming language. For number/arithmetic manipulation, there are many predefined functions available.
With the help of this program, we can take input and Add Two Numbers.
Algorithm to add the numbers:-
|
1 2 3 4 5 6 7 |
1. Declaring the variables for the program. 2. Taking the input numbers from the user in number format. 3. Adding the numbers and storing it in a variable. 4. End program. |

// Java Program to Add Two Numbers import java.util.Scanner; public class IntData {//Creating the class for the program in public type //Body of Main function of the program public static void main(String[] args) { //Declaring the required variable for the program. //Integer type variable to hold number value. // Creates a reader instance which takes // input from standard input - keyboard int fno,sno,sum; //Scanner is imported from the import package Scanner reader = new Scanner(System.in); //Taking the input from the user System.out.print("Enter first number: "); // nextInt() reads the next integer from the keyboard fno = reader.nextInt(); //Taking the input from the user System.out.print("Enter Second number: "); // nextInt() reads the next integer from the keyboard sno = reader.nextInt(); //Adding to numbers from the input. sum = fno+sno; // println() prints the following line to the output screen //Using the System.out.println(); System.out.println("Sum of numbers is : " + sum); } } |
Output:-
In the above program, we have first initialized the required variable.
- fno = it will hold the input number value from the user.
- sno = it will hold the input number value from the user.
- sum = it will hold the sum value of the numbers.
Taking input numbers from the user.
Calculating the sum of two numbers.
Printing the output sum of two numbers.
