Java ConcurrentHashMap.replace() is a method in the Java ConcurrentHashMap class that replaces the value associated with a specific key if the key is already present in the map. It ensures that the map is modified atomically, making it suitable for concurrent environments. Introduced in Java 2014 with Java 8, replace() is useful for modifying existing values without causing race conditions in multi-threaded applications.
