In this article I would like to share with you how to create inner classes in Java. Inner Classes are very fundamental concepts in object oriented programming in Java programming it makes our code more easier to understand and secure. In this example our program will ask the user to give two numbers and our program will compute the quotient of the two numbers. The code is written using Netbeans IDE that is free to download over the I hope you will find my work useful. Thank you.
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.
