The policy pattern defines a series of algorithms, encapsulates each algorithm, and allows them to be replaced with each other, and the policy pattern makes the algorithm independent of the customers who use it. The policy pattern enables these

Introduction of Adapter Mode (Brief Introduction) Adapter mode to replace a class with another interface expected by the customer. The adapter mode makes it possible for those classes that are not working because of incompatible interfaces to work

First, prototype (Prototype) mode The purpose of the prototype pattern is to specify the type of object to be created by giving a prototype object, and then create more objects of the same type with the method of copying the prototype object. From

Six basic guidelines for JAVA design patterns to followa single principle of responsibility: (Responsibility pinciple)　A class is responsible for only one responsibility. When more than one responsibility is required, new classes need to be added to

When generics are not used in the collection:1. Objects of any object and its subclasses can be added in2. Remove from class, strong to a certain type, there may be classcastexception exception1. Use generics in the collection:Format:list List = new

Strategy mode: A series of algorithms are defined to encapsulate each algorithm and make them interchangeable with each other. This mode allows the algorithm to be independent of the customers who use it. is a pattern of behavior.Policy mode

The policy pattern belongs to the behavior pattern of the object. The intention is to encapsulate each algorithm in a separate class with a common interface for a set of algorithms so that they can be replaced by each other. The policy pattern

Applicable occasions: 7.3 Application of Factory mode The easiest way to create a new object is to use the New keyword and the specific class. The extra complexity of creating and maintaining object factories is worth it only in some cases. These
