![]() This important book describes various development techniques and pitfalls in addition to providing twenty-three object-oriented programming design patterns. The Gang of Four are the authors of the book, " Design Patterns: Elements of Reusable Object-Oriented Software". Using the incorrect pattern for a situation or applying a design pattern to a trivial solution can overcomplicate your code and lead to maintainability issues. It is also important to apply patterns appropriately. It is more important to understand the concepts that design patterns describe, rather than memorising their exact classes, methods and properties. However, they should not be seen as prescriptive specifications for software. They give generalised solutions in the form of templates that may be applied to real-world problems.ĭesign patterns are a powerful tool for software developers. In the case of object-oriented programming, design patterns are generally aimed at solving the problems of object generation and interaction, rather than the larger scale problems of overall software architecture. What are Design Patterns?ĭesign patterns provide solutions to common software design problems. ![]() In this article their twenty-three design patterns are described with links to UML diagrams, source code and real-world examples for each. The Gang of Four are the four authors of the book, "Design Patterns: Elements of Reusable Object-Oriented Software".
