Quick Answer
Enums define a fixed set of named constants. Better than integer constants: type-safe (compiler catches wrong values), can have methods and fields, work with switch statements, implement interfaces. Each enum value is a singleton instance. Enum has built-in methods: name(), ordinal(), values(), valueOf(). EnumSet and EnumMap are highly efficient collections for enums.
