Passed and Failed Program in Java

This is a program in Java that I wrote using one dimensional array as my data structure that will check the number of passing and failing grade of students. The code is very simple yet very useful for students and other people who are getting started learning Java programming.

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.
