Just released, a free O’Reilly book on Reactive Microsystems: The Evolution of Microservices at Scale. Brought to you in partnership with Lightbend.

Here's something that can annoy the most experienced Java developers and is guaranteed to make people to mumble in job interviews (if that's your thing).

Java Riddle

On the face of it, the two variables are identical, but of a different type. So what's the problem here? 

Hint 1: This will work with a String. It will not work with an int array.

Hint 2:  This is the error you'll be getting (at least in Eclipse):

The field OBJECT_CONST cannot be declared static; static fields can only be declared in static or top level types

This hint is only more confusing. The error seems to apply to the integer field as well. So, what's the deal here?

If you know the answer, leave a comment.
