Javadoc is a tool that comes with the JDK, which you can use to generate documentation which looks like the standard Java API documentation.

It works like this: you put specially formatted comments above your classes, methods, interfaces etc., then run the Javadoc tool on your source code, and it then produces a directory containing HTML files.

See the documentation about Javadoc.

Javadoc comments start with /** and end with */. Here's a simple example:

It's a really cool to use I've just started to understand it better, its definatly worth reading more about creating classes & methods yourself first so its easier to understand the classes that come with the SDK and you can be well away creating GUI's - if you wanted

My advice from starting out is Javas own tutorial was tricky to understand at first but I didnt know where to look compared to your step-by-step over advertised tutorial websites

After I found the right place on Javas own site things started becoming more clearer and in depth

The Java tutorial has a few things in I don’t agree with, but it is by far the most comprehensive teaching resource I have ever seen for Java. I think in some places it might go too fast for beginners.
I agree. Here's the link:
