Java Program to Add Two Numbers Using Functions

import java.util.*;

public class Main{
    
    public static int sum(int num1, int num2){
        int ans = num1 + num2;
        return ans;
    }
    
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        
        System.out.println("Enter the first number: ");
        int n1 = sc.nextInt();
        
        System.out.println("Enter the second number: ");
        int n2 = sc.nextInt();
        
        int sum = sum(n1,n2);
        
        System.out.println("The sum of "+n1+" and "+n2+" is "+sum);
        
    }
    
    
}

Output

Enter the first number: 12
Enter the second number: 34 
The sum of 12 and 34 is 46

How Does This Program Work ?

Scanner sc = new Scanner(System.in);
        
System.out.println("Enter the first number: ");
int n1 = sc.nextInt();
        
System.out.println("Enter the second number: ");
int n2 = sc.nextInt();

First, the user is asked for two numbers. We are taking input from the user using the Scanner class in Java.

In this program, we have created a parameterized function “sum” with two parameters i.e. num1, num2 and we are returning the sum of the two numbers i.e. return num1 + num2.

public static int sum(int num1, int num2){
        int ans = num1 + num2;
        return ans;
    }

Then we call the function sum and receive the answer returned by the function in the sum variable

int sum = sum(n1,n2);

Then, we just display the result i.e. the addition of two numbers. This is the Java Program to Add Two Numbers Using Functions.
