Things possible in Eclipse that aren’t possible in IntelliJ? [closed]

Question

I have heard from people who swear by one or the other. Both are full-featured, excellent IDEs. But each has slightly different strengths. This is not meant to turn into a holy IDE war. Please downvote any flamebait answers. Thanks.

This is the analog of this question.

Answer 1

My favourite small annoyance in IDEA (and favourite small feature in Eclipse) is the positioning of the character when typing an opening curly brace (e.g. "{") or a semicolon. You'll have to enable it in Eclipse (Window/Preferences/Java/Editor/Typing: "Automatically insert at correct position: Semicolon, Braces")

With this just type ahead ("|" is the caret position)

while(| 

results (no magic yet) in

while(|) 

now type true{, results in

while(true) {| 

So simple, yet so powerful.

Also, in (e.g.)

System.out.println("Hello world") 

with the caret anywhere in that line, typing a semicolon will automagically type it at the end of the line. Backspace corrects, just like the usual autocorrection in your favourite wordprocessor.

Priceless. I'm physically no longer able to type a semicolon at the correct position on first try :)

Answer 2

Eclipse's incremental compiler lets you run unit tests even while there are compiler errors in unrelated code. IntelliJ relies on javac which doesn't emit bytecode unless all the code is valid.
