Does Java have something similar to XML documentation (summary) from C#?

Question

Java

Those who have not written in C# will probably not understand what I want, well, I don’t even know how to explain it, in general, when you write:
this. - with a dot at the end
, then in the IDE a list of members of this this appears - methods, fields, constants, etc., so I want this popup window (I don’t know how it’s called correctly, in C # it’s IntelliSense) to be some explanation for each member. Here's how to do this for your (own) class?

Answer 1

yes, and much more convenient than in C# (wrote both there and there), Javadoc
