What is the IntelliJ shortcut key to create a javadoc comment?

Question

In Eclipse, I can press Alt+Shift+J and get a javadoc comment automatically generated with fields, returns, or whatever would be applicable

Answer 1

Typing /** + then pressing Enter above a method signature will create Javadoc stubs for you.

Answer 2

Shortcut Alt+Enter shows intention actions where you can choose "Add Javadoc".

Answer 3

You can use the action 'Fix doc comment'. It doesn't have a default shortcut, but you can assign the Alt+Shift+J shortcut to it in the Keymap, because this shortcut isn't used for anything else. By default, you can also press Ctrl+Shift+A two times and begin typing Fix doc comment in order to find the action.
