You might already know that IntelliJ IDEA has the CTRL+P shortcut (Windows) and CMD+P (OX X) that brings up a brief description of which parameters are passed to the method. It's very handy and saves a lot of time that otherwise would have been spent looking up the method declaration.
Answer from Dmitry L on Stack OverflowIntelliJ IDEA autocomplete is uncanny

java - Easier suggestions in Intellij IDEA (no `CTRL+Space` and fuzzy search) - Stack Overflow

I'm not an IntelliJ IDEA user nor earning my bread with Java programming really, but after giving its Beta version a try, I'm impressed with how uncanny autocomplete there is. Many times I've been proposed with the option to autocomplete the whole line of code before even starting to type it. Granted, it doesn't always guess it right, but overall... it's so convenient.
So now I have questions. Does anybody know, is it the same in the non-Beta version? When did they add it? Does it use AI like Copilot or something? I remember using Community Edition very shortly a couple of years ago and don't remember the autocomplete being that good. Or do they disable it in the Community Edition?
I feel like IDEA is just on a completely different level compared to the other Java IDEs. Or any other IDEs for that matter...

IntelliJ IDEA 9 now supports what they call "super completion" which matches the behavior you are looking for and is available through their early access program.

IntelliJ IDEA 8 does not allow you to autocomplete more than one parameter at a time. You are forced to use Control-Shift-Space once for each parameter.
For me it was because I did not have a folder marked as Source Root (it appears in blue).
To fix, right click your root source directory -> Mark As -> Source Root.
Check to see if you accidentally turned on Power Save (File/Power Save Mode) I myself just discovered that File/Power Save Mode does turn it off. I was having the same problem and must have accidentally set Power Save Mode to on.
