Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2

No, if the string array would contain 3 elements, then index 2 would not cause that exception. — GhostCat, Feb 07 '19 at 19:22

This

String str = String.join(",", elements);

Returns a single string. Therefore this

String[] strArray = new String[] {str};

only has 1 element

You haven't provided any details on what your code is _supposed_ to do so I can't really say. I would update the question to include details on what the task your application is trying to accomplish. – Mike Feb 07 '19 at 19:22
