If someone drew several matrices on the whiteboard, would you be able to tell which (if any) of them were and NxN identity matrix? Obviously you would, if they lined up the indices nicely. But, you need to think about how you would do it programatically. Forget Java and just think about the algorithm you would use (in pseudo-code). Go row by row and think about how row N relates to row(N-1) and row(N+1) in an identity matrix. Don't forget about you base case as well (I1).
