Consonants Remover in Java

In this article I would like to share with you a sample program that will remove any consonants letters in a word or string in Java. The code is very simple and easy to understand.

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.
