How to find info on java libraries, classes, etc.?

P: n/a
I'm just starting to learn java. Naturally, I
am comparing it to languages that I am already
familiar with.
In Oracle, in Sqlplus, you can

describe procedurename
This will list procedure "headers".
It will show you all input and output parameters.
If you: describe pacakgename

Oracle will list all the internal procedures, and
the parameters required for each of the procedures.
Is there something similar in java?

Ie. I want to know all the built in functions, etc in:

java.io
java.lang
And, if I do know the particular function that I am
interested in, how do I describe it, and find out:
- the input parameters
- any return values
- any description/help

Thanks a lot

It's called the API docs, you can find them at the sun site:

http://java.sun.com/j2se/1.4.2/docs/api/

And as a beginner, you might consider just posting to c.l.j.help instead.
I also changed the followup to comp.lang.java.programmer since
comp.lang.java is not an official group anymore, although some servers
still carry it.
