Sum of Two Numbers Using Swing in Java

Hi guys thank you for visiting my site in this article I would like to share with you a sample program that I wrote using Netbeans and Swing in Java. I called this program sum of two numbers using swing in Java. The code is very simple and easy to understand. From my experience writing a GUI application for desktop application in Netbeans is very easy and simple I hope you will find my work uesful. Thank you.

My email address are the following jakerpomperada@gmail.com and jakerpomperada@yahoo.com.
