具體的設計模式，網上有很多介紹。本人蔘見 journaldev
| 模式 | 解決問題 |
|---|---|
| Builder | Too Many arguments to pass from client program to the Factory class |
| Factory | when we have a super class with multiple sub-classes and based on input, we need to return one of the sub-class |
| Prototype | When u need clone an existing object (shallow or deep copy) |
| Strategy | Define multiple algorithms and let client application pass the algorithm to be used as a parameter |
| Decorator | modify the functionality of an object at runtime |
| Composite | When we need to create a structure in a way that the objects in the structure has to be treated the same way |
| Bridge | Using abstract class replacing implement class to decouple |
| Facade | Unify a set of interfaces in a subsystem |
| Template method | define common functions in abstract class for all sub class |
