Design pattern is a general solution for solving repetitive problems in software design. Here are the pros and cons of design patterns:


Reusability: Design patterns provide a common solution that can be reused across multiple projects and scenarios.

Maintainability: Design patterns provide a structured way to make code easier to understand and maintain.

Extensibility: Design patterns achieve loose coupling by defining interfaces and abstract classes, making the system easier to extend and modify.

Improve code quality: Design patterns enforce the use of best practices, such as object-oriented design principles and design ideas, to improve code quality.

Communication efficiency: Design patterns provide a common language that can speed up the efficiency of communication between team members.


Complexity: Design patterns require familiarity with how they work in order to implement them correctly. As a result, beginners can be confused.

Overdesign: Overuse of design patterns can result in code that is overly complex and difficult to understand.

Performance issues: Certain design patterns can cause performance issues, such as using a large number of interfaces and abstract classes.

Not for all scenarios: Design patterns are not a one-size-fits-all solution, so they need to be chosen on a case-by-case basis.

Hope to adopt
A lot of
here to explain to you the advantages of
can improve the code reusability, readability and maintainability, can better meet the needs of customers, You can better grasp the complexity of the system, you can better grasp the scalability of the system. The disadvantage of
is that it may increase the complexity of the system, increase the development time of the system, and increase the maintenance cost of the system

the reference answer GPT ᴼ ᴾ ᴱ ᴺ ᴬ ᴵ < br / > the advantages of design pattern:

  1. Improve code reuse: Design patterns are derived from practices that help developers solve problems through proven best practices. The use of design patterns can improve code reuse and avoid duplication of wheel.
  2. Improve code maintainability: Adopting design patterns makes code cleaner and easier to maintain. Design patterns provide a standardized way to make code easier to understand and modify.
  3. Improve software scalability: Design patterns provide a well-scalable structure that can meet future requirements changes, thus avoiding the need for redesign and development when the system changes.
  4. Improve software readability: Using design patterns makes code clearer, easier to read, and understand. This is very important for projects where more than one person is working together.
  5. Reducing risk in software development: Design patterns are best practices that are constantly summarized in practice. Adopting design patterns can avoid risk in software development.

Disadvantages of design patterns:

  1. imposes additional overhead: The implementation of the design pattern requires additional code, which may increase development time and cost.
  2. can lead to over-design: The use of design patterns requires the developer to be experienced and competent, or it can lead to over-design, which makes the code more complex and difficult to understand.
  3. can make code more abstract: Implementations of certain design patterns can make code more abstract and difficult to understand. This can be difficult for beginners.
  4. may affect performance: The implementation of certain design patterns may affect the performance of software. Developers need to choose the right design pattern for the situation to avoid performance impacts.
