Any Udemy Java course suggestions?

Hello, As many of you probably already know, Udemy has a sale right now and I am looking through some of the courses, but there are so many to choose from. I'm interested to know if anyone has taken any courses that were particularly interesting or informative relating to Java. I'm not a total beginner (I'm a beginner, but I'm past learning about conditionals, loops, etc), so the course doesn't need to be super basic. If you have any suggestions for a course that may be at an intermediate level or maybe an object-oriented course that you took and enjoyed, I'd love to hear about it!
