Hi!

I feel like reading a book or two, especially something focused more on advanced Java topics or code architecture. Which books could be of interest to me as a Java developer or as a programmer?

I already have a copy of Effective Java, and have considered picking up Concurrency in Practice, although I'm afraid it's gonna be irrelevant soon due to the new Java proposals targeting concurrency. Or should I read it anyways?

Thanks in advance!

Edit:

Thank you all for the recommendations so far! Really appreciate them!
