Do Java arrays have a maximum size?

Question

Is there a limit to the number of elements a Java array can contain? If so, what is it?

Answer 1

There are actually two limits. One, the maximum element indexable for the array and, two, the amount of memory available to your application. Depending on the amount of memory available and the amount used by other data structures, you may hit the memory limit before you reach the maximum addressable array element.
