I've been coding in a variety of languages and platforms for decades, starting with the Commodore 64 back in the 80s(?). I've recently coded some apps in Apps Inventor and realized how hard it is to cross platforms. So I decided to re-code into JAVA, which I first had to teach myself.
As of this writing I'm working on my first two JAVA apps. One is a useful tool and the other is a silly game. I'm an old retired guy and just do this for fun, the challenge, and to keep my mind sharp.
