java.util.EnumMap is a class in the Java programming language that implements the Map interface and is specifically designed to be used with Enum keys. It is a high-performance, specialized map implementation that provides efficient storage and retrieval of key-value pairs where the keys are enum constants. It offers all the standard functionality of a map, such as adding, removing, updating, and retrieving elements, but with the added benefit of being optimized for enum keys. EnumMap is type-safe, ensuring that only keys of the specified enum type can be used, and also provides a natural ordering of keys based on their enum declaration order. This makes it a useful choice for scenarios where enum constants are used as keys and efficient performance is a priority.
