问题
Some IDEs offer the feature to automatically format a line or block of code after finishing it e.g. by writing the closing curly or semicolon. I find it hard to believe that IDEA does not offer this kind of feature. Or does it?
If you know how to turn it on - or if I maybe need some plugin - let me and the world know, please!

There is no automatic reformat feature, related requests:
- IDEABKL-5806 Automatically trigger code formatter on file save
- IDEABKL-475 Hard (auto-)reformat code
See also my answer to the similar question with the Complete Current Statement workaround.

If it's a single line, you can use the Complete Current Statement action (which adds a closing bracket, semi-colon, and so on) with ctrl-shift-enter - this seems to reformat the whole line.
Otherwise, you can obviously rebind ctrl-w and ctrl-alt-l (to reformat selected text) or just ctrl-alt-l (reformat whole file) to faster / easier keybindings so that you can quickly reformat whenever you want to.
