You can take a look at this one to get started.

If you are building your own API then it is really necessary to create Java Document for your custom API. I think as a beginner you don't need to get in depth with it right now.

Hi,

I suppose you are talking about Java API documentation. In the same way you can create API documentation for your own code, as Balasubramanian mentioned, Java API has its own documentation.

This documentation (also known as javadoc) contains information about all the classes made available by a standard JVM and how to use it. So, you don't have to code everything by yourself but rather use these utility and foundation classes.

You can try googling by "javadoc" and find more info about it.

Does that answer your question? Or were you asking something else?

What you get in the API documentation (here) is a list of classes and packages. For each class (or interface or enum) it gives, more-or-less from top to bottom,

Class name, and what it inherits from

Description of the class

List of its constructors

List of its fields

List of its methods

List of methods inherited from superclasses

Description of its constructors

Description of its fields

Description of its methods.

You will have to pick a class, any class, maybe this one: HashMap and read through its web page.

You just have to get used to the format; it does take a little time.

Responses also in the duplicate thread (which has been closed)

Thanks all

It really cleared my doubt

Java docs basically helps you to gives details of all the methods present in that class and its hierarchy.Little sample code is also present some times.
