Looks fine.

There are little nits that could be fixed, but no need if that invalidates testing already done.

For example:
 - interfaces are implicitly static, so "static interface" is redundant
 - "delimiter" can be final
 - "elements" can be final and eagerly initialized in constructor
 - "elements" can be ArrayList
