Nowadays, I am more interested in PHP and mySQL because of activities related to my websites, so it has been awhile since I dabbled with the Java programming language.
So why the concern?
Lately, I have been thinking about writing a small Java utility for a personal project of mine. But I definitely needed a quick refresher. I found a reliable Java tutorial that covers the fundamentals of programming in the Java programming language. Here are the topics covered: object-oriented programming concepts, language basics, classes and object, interface and inheritance, numbers and strings, generics and packages.
I will, undoubtedly, have to look over my old programs, too.
