Spring / Spring interview questions
Difference between Dependency Injection and Factory Pattern.
Using factory your code is still actually responsible for creating objects. By DI you delegate that responsibility to another class or a framework, which is separate from your code.
Use of dependency injection results in loosely coupled design but the use of factory pattern create a tight coupling between factory and classes.
A disadvantage of Dependency injection is that you need a container and configuration to inject the dependency, which is not required in case of factory design pattern.
