It is probably a good idea to keep the
thread this post was split from for “idioms”.
I can think of a few books: I have all the following:
Cay Horstmann: Core Java II 2015/6 edition (I think 10/
e), volume II
Also Core Java SE8/Java SE9 for the Impatient (two books presumably very similar: I have the Java9 edition). Don't confuse this book with the beginner's book with a similar name.
Urma Fusco and Mycroft: Java8 in Action (Manning 2014) and Modern Java in Action which is a more recent version of the same book.
Maurice Naftalin Mastering Lambdas: Java Programming in a Multicore World (Oracle Press 2014).
Ken Koiusen Modern Java Recipes (O'Reilly 2017) Slightly different: this isn't a tutorial but a cookery book supplying recipes for particular problems.
Other people will doubtless have their recommendations, too.
