Civil Status Checker in Java

A very simple program that I wrote in Java using NetBeans IDE to ask the user it's civil status whether the user is single, married, divorce or annulled it will display the result on the screen. The program is very simple I just wrote this for beginners that are 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.
