public interface ResourceIterator<T>
extends Iterator<T>, Closeable

Closeable Iterator with associated resources that needs to be managed.

However, if your code might not exhaust the iterator, (run until Iterator.hasNext() returns false), ResourceIterator provides you with a close() method that should be invoked to free its resources, by using a finally-block, or try-with-resource.
