Explain the Dependency Inversion Principle (DIP). How does it relate to Dependency Injection?

Difficulty: 5/10

abstraction, dependency injection, decoupling

Dependency Inversion Principle

DIP states that high-level policy should not depend directly on low-level implementation details; both should depend on abstractions. It also states that abstractions should not depend on details—the details should depend on abstractions. Dependency Injection is a technique for supplying those dependencies from outside the consumer. Therefore, DIP is a design principle, while DI is one practical mechanism for implementing it.
