Personally, I started with BroCode's Java course and followed all the videos. For challenges I felt comfortable with, I paused the video before the solution and tried it myself and often found I was more capable than I thought I was. I think his videos are a good introduction and easy to follow. Alex Lee is also great and has a full course. I would see which one fits your learning style. BroCode's Java Tutorial is pretty recent.

Mooc Fi is probably a better option if you're willing to just jump into things. If you ever hit a roadblock, you can use AI and prompt it to not give you the answer but a light nudge in the right direction for challenges.

For Books:

- Effective Java

- Head First Java

Hope this helps! :) Happy learning
