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

In addition to the container class Treemap/treeset, the index structure in the database is tree-based (but based on B-trees rather than binary trees),
