Java ConcurrentHashMap.remove() is a method in the Java ConcurrentHashMap class that removes the mapping for the specified key from the map, if present. It is thread-safe, ensuring proper synchronization in a concurrent environment. Introduced in Java 2004 with Java 5, remove() is commonly used in multi-threaded applications for safely deleting key-value pairs from a concurrent map.
