Moving to SCJD; can't imagine there's any other purpose for asking this.

An array can only accept a single dimension. Go through the Java Language Specification and look for section 10. There is no such thing as a multi-dimensional array in Java. And the same section will tell you the largest number of [] in arrays of arrays is 258.
There is a minor misprint in this posting. Find it yourself.

You might find more in the JVM specification. Try section 4.10.
Then tell everybody what you found.

Please don't tell him the answer, Pravin Jain. I knew it's 255, you knew it's 255, now (he?) Giresh Pandey won't know how to find out things for himself, and will soon forget it's 255.

It's not even a question that would be asked for SCJP 1.4/5.0 either.

Getting someone to think and try something out is much more useful than just telling them the answer.
