Almost sure to be asked in every company using any Dependency Injection framework ( Spring, Guice etc )

Q1. What is Dependency Injection or IOC ( Inversion of Control ) ?

Ans. It is a Design Pattern that facilitates loose coupling by sending the dependency information ( object references of dependent object ) while building the state of the object. Objects are designed in a manner where they receive instances of the objects from other pieces of code, instead of constructing them internally and hence provide better flexibility.
