Addition of two numbers program in Java

 

Welcome my Java fellows!

 

In this blog we are going to develop a program in java language which will add two numbers. There are different ways in java to add two numbers. We will explore only three types to add two numbers in java language.

 

Method 1: Adding By Direct Static Method:

 

In this method, we will add the two numbers directly using the static program. So let’s we want to add the 40 and 100. We can add these numbers by using this code.

 

Code:

public class Main{
    public static void main(String[] args)
    {
        System.out.println(40+60);
    }
}

 

Output:

 

Here is the output of this program when we compile it using the InteliJ Idea IDE.

 

 

 
Method 2: Adding By Variable Static Method:

 

Adding by Variable static method is same like as adding by direct static method. The only difference is the in variable static method. We will store our numbers in the variables. Then perform addition operation and store the result in another variable and than print this result on screen. This can be achieved by using following program.

 

Code:

 

public class Main{
    public static void main(String[] args)
    {
        int num1=40;
        int num2=50;
        int result;
        result=num1+num2;
        System.out.println(result);
    }
}

 

Output:

This program of addition has the following output.

 

 
Method 3: Addition by taking the values from user at run time:

 

In addition by taking the values from user at run time our program will ask the user to enter the numbers of their own choice which they want to add. The program will prompt the user to enter first number and then second number. Add these numbers and store the result in a third variable and display the result. The program segment is as follow.

 

Code:

 

import java.util.Scanner;
public class Main{
    public static void main(String[] args)
    {
       int num1;
       int num2;
       int result;
        System.out.println("Welcome in Addition Program");
        Scanner input=new Scanner(System.in);
        System.out.println("Enter First Number :");
        num1=input.nextInt();
        System.out.println("Enter 2nd Number :");
        num2=input.nextInt();

        result=num1+num2;
        System.out.println("Addittion of two numvbers ="+result);

    }
}

 

Output:

 You can see the running of this program in the below snapshot.
