Year Level in Java

In this article I would like to share with you a sample program that I wrote in Java using NetBeans as my integrated development environment I called this program year level checker or determiner that show the user how to use if else statement in Java. This program is for beginners that are very new in Java programming.

I hope you will find my work useful and beneficial. If you have some questions about programming, about my work please send me an email at jakerpomperada@gmail.comand jakerpomperada@yahoo.com. People here in the Philippines can contact me at  my mobile number 09173084360.

Thank you very much and Happy Programming.
