I actually agree with you here that OO is overused. Java has added quite a bit of FP in recent years though. Lombok makes immutable data classes trivial. Improved interface support for default methods make it possible to largely ignore OO if you don't want it. FP is mostly a community effort at this point, but solid. Java Streams are decent for basic stuff like map/filter but RXJava is extremely powerful if you want the complexity it comes with. Vavr is nice for adding more FP types too
