SOLIDPrinzipien

SOLID principles are a set of five design principles for object-oriented programming and design. They are intended to make software designs more understandable, flexible, and maintainable. The acronym SOLID stands for Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion.

The Single Responsibility Principle (SRP) states that a class should have only one reason to change. This means a class should have a single, well-defined purpose. The Open/Closed Principle (OCP) suggests that software entities should be open for extension but closed for modification. This implies that new functionality should be added by creating new code rather than altering existing code.

The Liskov Substitution Principle (LSP) states that objects of a superclass should be replaceable with objects of its subclasses without altering the correctness of the program. This ensures that inheritance hierarchies are well-formed. The Interface Segregation Principle (ISP) dictates that clients should not be forced to depend on interfaces they do not use. This promotes the creation of smaller, more specific interfaces.

Finally, the Dependency Inversion Principle (DIP) states that high-level modules should not depend on low-level modules. Both should depend on abstractions. Abstractions should not depend on details. Details should depend on abstractions. Adhering to SOLID principles can lead to more robust, adaptable, and scalable software systems. They are widely adopted by software developers to improve code quality.
