This blog post will provide you with the source code of a program written in Java to add two numbers. So let's get started. Source Code:  import java.util.Scanner;public class AddTwoNumsApp1 {    public static void main(String[] args) {        Scanner Sum2Nums = new Scanner(System.in);        System.out.println("nEnter the first number: ");        int FirstNum = Sum2Nums.nextInt();        System.out.println("nEnter the second number: ");        int SecondNum = Sum2Nums.nextInt();        int Total = FirstNum + SecondNum;        System.out.println("nThe total of 2 numbers are: "+ Total + ".n");       Sum2Nums.close();      }} Output: That's it, a Java program to add two numbers has successfully been created.
