Payroll System in Java Using Text File

In this article I would like to showcase the work of my best friend and programming buddy Mr. Bernie Saligumba he is a programmer just like me that has a great passion in learning specially in writing codes. He called this program payroll system in Java using text file as the depository of records.

 If you have some questions please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.


People here in the Philippines can reach me at my mobile number 09173084360.


Thank you very much and Happy Programming.
