Question

Accepted Answer

Dependency injection is a design pattern where the dependencies of a class are provided externally rather than created internally.

Dependency injection helps in achieving loose coupling and improves testability and maintainability.
There are three types of dependency injection: constructor injection, setter injection, and interface injection.
In constructor injection, dependencies are provided through the class constructor.
In setter injection, dependencies are provided through setter methods.
In interface injection, dependencies are provided through an interface that the class implements.
Dependency injection frameworks like Spring can be used to automate the injection process.

Dependency injection is a programming technique that makes a class independent of its dependencies

Accepted Answer

Dependency Injection (DI) is a programming technique that makes a class independent of its dependencies. Creating objects directly within the class is inflexible because it commits the class to particular objects and makes it impossible to change the instantiation later independently from the class.
