Java Expert

[Harris Tanu]

I have been programming java for 8 years. My only java certification was JCEA which I took 1 year ago.
Personally I've been working on fundamental java, J2EE and some emerging technologies.

I would like to measure my knowledge as how far my technical skills in Java is. so my question was:
-How to define someone is a Java expert?
-What essential knowledge must he have?
-What other technical knowledge must he posses?

A Java expert should handle any kind of Problem at anytime without any reference ...should keep everyhting in finger tips

Thanks

[Arun Kumarr]

There is always something to learn.

[Campbell Ritchie]

Without reference, Ramesh Shankar? Please . . . .

You ought to know where to find the references, having a copy of your favourite book, the API specification, at your fingertips as you work.

If you run into somebody like Chad Fowler you better be prepared to answer a simple question like:

How would you write a program, in pure Java, that would make the Java Virtual Machine crash?

[Harris Tanu]

maybe my question is too abstract..

Let's say.. with my current working experience, I still believe, I'm far behind those guys such as Gaving King(Hibernate) or Marc Fleury(JBoss).
The easier question could be: "How can I be one of them one day when I work on my technical skills?" What are the steps?

It's not necessary to know all the methods in Java API. Java doc has every thing , you should know how to use it.

That's really a very different question. I don't think those people are best described as *Java* experts, but better as *software development* experts. That is, there is much more to it than just knowing Java exceptionally well. In fact, focusing on Java probably is exactly *not* what made them what they are - it needs diversity to become really good.

Let me summarize the list of "goals of knowledge portfolio managment" from the book "The Pragmatic Programmer" - the whole book would probably be a good investment for you, it has lots of good advice:

- Learn at least one new language every year.
- Read a technical book each quarter.
- Read nontechnical books, too.
- Take classes.
- Participate in local user groups.
- Experiment with different environments.
- Stay current.
- Get wired. (That probably is the books way of saying "participate at JavaRanch" )

What you said, makes sense.
It is more to learn besides java. They know much more than Java which I should describe them as 'software development expert'.

as for the pragmatic programmer's book, it looks interesting.
Will be getting the book soon.
