Design Patterns in Java development 23

design mode (Patterns)

Design pattern is a set of repeated use, most people know, after the purpose of classification, code design experience Summary. Design patterns are used for reusable code, making it easier for others to understand the code and to ensure the reliability of the code. There is no doubt that design patterns win over others in the system. Hope that the vast number of process enthusiasts, learn the design model, do a good software engineer.

I. Classification of design Patterns

In general, design patterns fall into three broad categories:

Create patterns, total five types: Factory method mode, abstract Factory mode, singleton mode, builder mode, prototype mode.

Structure mode, a total of seven kinds: Adapter mode, adorner mode, proxy mode, appearance mode, bridge mode, combined mode, enjoy meta mode.

There are 11 types of behavioral Patterns: Strategy mode, template method mode, observer mode, iteration sub-mode, responsibility chain mode, Command mode, Memo mode, state mode, visitor mode, mediator mode, interpreter mode.
