What is SOLID Principles Breakdown?

Five object-oriented design principles that guide developers in creating maintainable, flexible, and scalable software systems.

SOLID is an acronym for five design principles. Single Responsibility: a class should have one reason to change. Open/Closed: software entities should be open for extension but closed for modification. Liskov Substitution: objects of a superclass should be replaceable with objects of its subclasses without breaking the application. Interface Segregation: clients should not be forced to depend on interfaces they do not use. Dependency Inversion: high-level modules should depend on abstractions, not concrete implementations. Together, these principles reduce coupling, increase cohesion, and make codebases more adaptable to change over time.
