Solution. The Strategy pattern suggests that you take a class that does something specific in a lot of different ways and extract all of these algorithms into separate classes called strategies . The original class, called context, must have a field for storing a reference to one of the strategies.
Read moreWhat is the difference between pattern and strategies?
State Pattern defines the “what” and “when” part of an Object. Example: What can an object when it’s in a certain state. Strategy pattern defines the “How” part of an Object. Example: How a Sorting object sorts data.
Read moreWhat is the difference between strategy design pattern and State design pattern?
State design pattern is used to define and manage state of an object, while Strategy pattern is used to define a set of interchangeable algorithm and lets client to choose one of them. So Strategy pattern is a client driven pattern while Object can manage there state itself.
Read moreWhat is the difference between strategy and decorator pattern?
The strategy pattern allows you to change the implementation of something used at runtime . The decorator pattern allows you augment (or add to) existing functionality with additional functionality at run time.
Read moreWhat is strategy design pattern example?
Strategy pattern is also known as Policy Pattern. We define multiple algorithms and let client application pass the algorithm to be used as a parameter. One of the best example of strategy pattern is Collections. sort() method that takes Comparator parameter .
Read moreIs strategy a pattern?
Strategy is a behavioral design pattern that lets you define a family of algorithms, put each of them into a separate class, and make their objects interchangeable.
Read moreWhat does the strategy pattern solve?
The strategy pattern is used to solve problems that might (or is foreseen they might) be implemented or solved by different strategies and that possess a clearly defined interface for such cases .
