Yes, that's expected. The toString implementation of any array is not
all that pretty. It follows the basic default pattern of
<class-name>@<system-hash-code>. In this case, because it's an array
class, it starts with [, and because it's "int" the special short name
for that is I so you see "[I" as the class name.

Use Arrays.toString(intArray) to get the behavior you probably want.
