Bridge pattern of structural mode
definition:
Separate the abstract part from its implementation part so that they can change independently. It is an object structure mode, also known as handle and body mode or interface mode.
The bridge mode is similar to the multiple inheritance scheme, but the multiple inheritance scheme often violates the principle of single responsibilit ...

Singleton design pattern - Enumeration singleton - singleton optimization
preface
Singleton mode is the simplest of Java design modes. You only need one class to implement singleton mode. However, you can't underestimate singleton mode. Although it is relatively simple in design, you will encounter many pits in implementation. Therefore, fasten your safety belt and get on the bus.
Definition of singleton mode

Design Pattern Factory Pattern
After learning object-oriented programming, learn to create objects using keywords"new" To create objects, but creating objects in this way is a bit redundant and too coupled when a complex and multiple objects need to be created, and it is not easy to be understood. Factory pattern is used to create objects
First, the simple factory mode.
