Java EnumSet: Efficient and Compact Enum Handling

EnumSet is a specialized Set implementation in Java for use with enum types. It is designed to be compact, efficient, and fast, making it an ideal choice for working with enums. EnumSet provides methods for creating and manipulating sets of enum constants. It also supports iteration, searching, and adding/removing elements.

This example demonstrates how to create an empty EnumSet, add elements, create an EnumSet with specific elements, combine two EnumSets, and iterate through the elements.
