The 8th chapter of the design pattern-strategy mode (Java implementation)　　"Year ago Big bargain, Ah, now Barber rushed 500 to get 300, rushed 1000 to send 500." Fish brother hurriedly charge Ah, haircut this thing basic one months a back, very affordable AH. However, the boss of the barber shop is so silly, rushed 1000 to send 500, than two times 500, so you can send 600. "It only means that you are not ve

strategypattern, the responsibility for selecting the particularImplementation to use are done by the Client object and are given to theContext of the strategy pattern. Coupling of strategy with contextThe strategy pattern requires that the algorithms that are encapsulated must be outside the class (Context) in which they are used. That is to say

Design Pattern Explained Reading Notes 4 -- Strategy, patternexplainedWhat? Define a family of algorithms, encapsulate each one, andMake them interchangeable. Strategy lets the algorithmVary independently from the clients that use it. -- GOF Define a series of algorithms, encapsulate each and make each encapsulation replaceable. The

Strategy Mode (Strategy pattern) embodies the principles of two very basic object-oriented design: The concept of encapsulation change and the use of interfaces in programming, rather than the implementation of interfaces. 1, the definition of the policy model: Defines a set of algorithms that encapsulate each algorithm and allow them to be interchangeable. The p

Mind Mapping:Let's take a look at the popular explanation of strategy design pattern:With different types of MM dating, to use different strategies, some of the film is better, some go to eat snack effect is good, some go to the seaside romantic most suitable, but the purpose is to get mm heart, I chase mm Jin sac there are many strategy oh.Policy mode:The policy

The rule mode allows algorithms to change independently of customers who use it. 2 Mode composition 1) abstract policy role (Strategy ): A policy class is usually impl

? design pattern--Strategy mode1, Definition: Policy mode, also known as the algorithm cluster mode, is defined by different algorithm families, and can be replaced between each other, this mode allows the algorithm to change independently of the customer using the algorithm.2, "strategy" Understanding: A strategy is a

Design Pattern in. Net -- Strategy Pattern I. Mode Overview "Interface-oriented programming" is the most important principle in object-oriented programming. According to the principle of "encapsulation change", we often abstract and define the easy-to-change part as an interface. The caller only needs to know the external definition of the interface. In the design
