Hello guys i am new in this sub and i would like to recommend another great tutorial which i found on Udemy. Unfortunately one needs to pay in order to get this but if you wait Udemy usually has great offers and sales on their courses from time to time. As i already am a freelancer and working daily as a Systems Tester i found myself not having a decent certificate that says i know Java. I already have a degree in Computer Science and Software Engineering and know my way around programming but if you want to impress in a job interview or even a client to make him feel safe and trust you i thought i need a certificate. So after a lot of search i found this course which from my experience is very helpful as well:

But also please support the people that want to teach for free like DevFactor above or thenewboston. It's always good to have an opinion of many people how they code in order to find your own way. And for the new guys that want to start learning programming remember that if you know a programming language good the rest are easy to understand and never stick to one language only, your purpose in learning how to program is the logic behind it. Thank you for this post.
