The Enum class in Java is the base class for all enumerations. An enum is a special type of class that represents a group of constants (unchangeable variables, like final variables). Enums are used to create a collection of constants that can be used to represent a specific set of values, such as days of the week, months of the year, or directions (north, south, east, west).
This guide covers various methods available in the Enum class. Each method is described in simple terms to help beginners understand how to use them. These methods provide functionality to compare, retrieve metadata, and interact with enum constants effectively.
For more detailed information, please refer to the official Java SE Documentation.
