Java ConcurrentSkipListMap.floorKey() is a method in the Java ConcurrentSkipListMap class that retrieves the greatest key less than or equal to a given key, or null if no such key exists. It is a thread-safe operation often used in range queries or navigable maps. Introduced in Java 2004 with Java 5, floorKey() is useful for ordered data structures requiring boundary checks.
