In the previous series, we introduced the basic data types, classes, and interfaces used to represent and operate data in Java. This section discusses enumeration types in Java.
Enumeration is a special type of data. Its values are limited and can be enumerated. For example, a year has four seasons and a week has seven days, although classes can also
