You will get compile time error at LINE X saying b3 is not initialized. So you need to specify constant values to the array b3 or either allocate memory using new operator. b3 = new byte;
and as far as the original question is concerned yes both b2 and b3 are two dimensional arrays.
A word of advice: If you are planning to give the certification , download java sdk from sun web site and try out the code. You need to have lot of coding practice, reading books is not just sufficient.
Good Luck !!!

Ofcourse Neelima , You can assign if the arrays are not uninitilized.
And the above code compiles fine.
Hope that helps [ October 16, 2005: Message edited by: Sandeep Chhabra ]
