What is the advantage that we see with a Strategy pattern?
Advantages of the Strategy Pattern Clean code because you avoid conditional-infested code (not complex). More clean code because you separate the concerns into classes (a class to each strategy).
What is the difference between strategy design pattern and State design pattern?
State pattern helps object to manage state, while Strategy pattern allows the client to choose different behavior….Difference Between State and Strategy Design Pattern in Java.
| STATE PATTERN | STRATEGY PATTERN |
|---|---|
| Change in State can be done by Context or State object itself. | Change in Strategy is done by the Client. |
What are the advantage of the state design pattern?
Advantages. The State pattern minimizes conditional complexity, eliminating the need for if and switch statements in objects that have different behavior requirements unique to different state transitions.
How does the state pattern work?
In the State design pattern, an object’s behavior is the result of the function of its state, and the behavior gets changed at runtime depending on the state. This removes the dependency on the if/else or switch/case conditional logic.
What is the purpose of a strategy pattern?
The strategy pattern stores a reference to some algorithm or code and supplies it wherever required. So, in short, the strategy design pattern is one of the many defined algorithms in the design pattern family, which may be applied or used on data.
When to use strategy design pattern in Java?
So, in short, the strategy design pattern is one of the many defined algorithms in the design pattern family, which may be applied or used on data. The ability to decide which algorithm to use at runtime allows the calling or client code to be more flexible and reusable and avoids code duplication.
Which is better factory design pattern or strategy?
The client or context does not know which strategy (algorithm) it has to use. The factory design pattern is a creational design pattern, which provides one of the best ways to create objects. This pattern uses factory methods to deal with the problem of creating objects without specifying the exact class of the object that it has to create.
How are algorithms implemented in a strategy pattern?
Strategy enables the clients to choose the required algorithm, without using a “switch” statement or a series of “if-else” statements. Data structures used for implementing the algorithm are completely encapsulated in Strategy classes. Therefore, the implementation of an algorithm can be changed without affecting the Context class.
