Hey everyone! At my current university we study C++ and Python, so I have a solid programming foundation. I'm not starting from absolute zero. However, I'm applying to a master's program at a different university, and their admission process includes a Java coding exam that goes into quite some detail.

I'm not looking for a beginner "Hello World" course. I want resources that will take me from "I understand OOP and programming fundamentals" to genuinely being strong in Java: things like the standard library, collections framework, generics, concurrency, etc.

What would you recommend? Books, courses, YouTube channels, practice platforms — anything that helped you really get Java rather than just learn its syntax?

Thanks in advance!!!
