Positive and Negative Numbers in Java

This simple program will give you a first hand idea how to use one dimensional array in Java. What the program does is to ask the user to give a series of numbers and then the program will display the positive and negative numbers that is being given by our user.

I hope you will find my work useful and beneficial. If you have some questions about programming, about my work please send mu 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.
