Yes. I developed multiple apps. I am self-taught in Java. I do it for 7 years now. I actually thought I am a fake programmer, with actually no skills at all. But I discovered that I can pass the Oracle Certified Associate (OCA) blindfolded, and probably also the Oracle Certified Professional (OCP) too. The animations on my channel are programmed in Java. I could do more different animations, but my laptop is too slow to render them without to become jerky.
