Remember that in Java, a 2 D array is just an array of arrays.

You can use a simple counter variable for each dimension.

There are standard conventions for iterating through the whole of an array. You will doubtless find them in this part of the Java tutorial.

I trust you are looking at the Java tutorial and the API documentation whenever you go anywhere near a Java editor?
