How to learn java library from API docs?

I'm a beginner in this Java.
I learnt Library functions in C from the Help file of my compiler
( Turbo C++ 3.0 )
How can I learn Java's library from the API docs?
Is it possible?
I mean ... If I dont know anything about Swing and If I want to
program some Swing application; I just start refering the API docs
instead of reading some book on Swing.
Is it possible to learn some Java library without reading any book and
by just refering to API docs?

It is possible, but it may not be easy.  If you can find the Sun Java
docs then you can also find the Sun Java tutorials, which a probably a
better way to get started.

Mind you, the Javadocs are an excellent and important source of information,
particularly the package-level docs.

Multi-posting is the practice of sending the same message independently to
separate newsgroups, and is both ineffective and somewhat rude.  Most of the
Java newsgroups have substantial overlap in their readership; your message
will get through if you send it to only one of them.  Furthermore, a person
won't enter an answer only to find that it is not in the conversation when
viewed from another group.  It's not a good idea to fragment the
conversational threads in that manner.

Please do not multi-post.  If you really feel the need to redundantly post
redundantly to redundant newsgroups, use "cross-posting", where the same
message posts simultaneously to all of them in a linked way.

People started answering you on clj.help only to find that you'd gone and
started over on clj.programmer.

[snip remainder of OT tangent]

I don't see anywhere where you answer the OP's question, and I don't
see anything to make what you did write relevant. Why would one
question get a straight answer, and another answer with nothing
visibly different (in the body or the headers) about it get a useless
response like the one you just wrote? And yet that's what I see here.
Nothing different about various questions, but something very
different about the attitude you had when answering them.

Huh.  You must've missed my first post to their question, then.

This is substantially the same information that was provided in the clj.help
version of this thread, joined here with the clj.programmer line for
everyone's convenience.

After you've gotten a gander at the tutorials, Sun also has delightful white
papers.  While they might not directly reveal code idioms you want to use
(though many do), they provide much insight into the mindset of the Java
universe and the way things work.

IBM developerWorks
<http://www.ibm.com/developerworks/>
has an entire tree devoted to Java that is priceless.

I'll second that.  I find multi-posting to be
counter-productive, and very irritating as well.

That WAS your first post to their question. This thread has only six
posts. The OP's question, your OT followup, my followup to your
followup, your post I'm replying to now, Zig's more helpful separate
response to the OP's question, and your response to Zig. Seven now,
including this post. More if you read this later and there've been
more new posts, which will all be dated after this post's timestamp.

Google's archive shows nothing after the OP's question and before your
OT followup, from you or anyone else, to this thread. Even if
something had been posted with X-No-Archive: Yes I'd see it now as
it's been less than six days since the thread was born.

So no, I didn't miss your first post to their question. I followed up
to your first post to their question. :P

The first post on this topic from Lew that I could find, either on the
UCSD NNTP server or on Google groups, is
http://groups.google.com/group/comp...f0d4396f06d0f22
It was a substantive reply.

It was posted to comp.lang.java.help. If you looked only in
comp.lang.java.programmer you would not have seen it. Confusion due to
some posters only seeing part of the discussion is a natural but
unfortunate consequence of multi-posting.
