Java ConcurrentSkipListSet.pollFirst() is a method in the Java ConcurrentSkipListSet class that retrieves and removes the first (lowest) element in the set. It is a thread-safe operation designed for concurrent environments. Introduced in Java 2004 with Java 5, pollFirst() is useful for managing ordered sets where the smallest element must be processed or removed.
