Spring Core - Basic

Dependency Injection People that start working with Spring benefit from a basic understanding of dependency injection since Spring is an application container that is based for the larger part on this paradigm. Building an application using Spring requires you to adopt a certain way of application design that is fundamentally different from the way you designed applications without dependency injection (i.e. by having beans explicitly look up dependencies themselves).

• Describe dependency injection.
• Describe its advantages (and disadvantages).
• Differentiate setter injection from constructor injection (note that method injection is not an objective for this exam).
