The Singleton mode is one of the most common today. It is an object creation mode used to produce a specific instance of an object. It ensures that only one instance is generated for a class in a system. In Java, such behavior brings two benefits:1):

In Singleton mode, the most important concern is the number of object creation times and the time when the object was created. The Singleton mode can be very simple, and only one class is needed to complete it (look at the poor UML diagram in this
