Java provides various data structures to store and manipulate data efficiently. One such data structure is EnumMap, which is a specialized implementation of the Map
interface. In this article, we will explore EnumMap in detail, including its purpose, advantages, and use cases, with examples to illustrate its functionality.

Understanding EnumMap
An EnumMap
is a concrete implementation of the Map
interface that uses an enum
type as its key. Unlike other Map
implementations like HashMap
or TreeMap
, EnumMap
is designed specifically to work with enum types.
When working with enum keys, enumMap is better compared to general-purpose Map
implementations. Because enumMap’s specialized design allows for more efficient memory usage and better performance.
