It isn't necessary in any language, but it sure is useful.

I don't know what you mean by better languages, but I program comfortably in variety of languages(Ruby, Python, C, C++, Java, Clojure, Lua, Racket, go, JS, perl...) and haven't found a single language in which context aware auto-complete, assisted re-factoring, looking up inline documentation etc isn't useful.

Generating get/set and abstract method bodies is only necessary in Java.

Find-and-replace, auto-complete and docs are of course useful generally.

"Generating get/set and abstract method bodies is only necessary in Java" On smalltalk instance variables are private, so if you want get/set it's value you need a getter/setter. You can argument that this is bad oo design, but it's not java exclusive.
