Java EnumMap.put() is a method in the Java EnumMap class that adds a key-value pair to the map, where the key is an enum constant and the value is associated with that key. EnumMap is optimized for use with Java Enum types and offers high performance when dealing with enums. Introduced in Java 2004 with Java 5, put() is frequently used in applications that require efficient mapping of enum constants to values, such as in configuration management or state machines.
