Overview

Beginning with JDK 5, enumerations were added to the Java language, and they are now an integral and widely used part of Java.

Singletons often control access to resources such as database connections or sockets. For example, if you have a license for only one connection for your database or your JDBC driver has trouble with multithreading, the Singleton makes sure that only one connection is made or that only one thread can access the connection at a time. If you add database connections or use a JDBC driver that allows multithreading, the Singleton can be easily adjusted to allow more connections.
