    Two things which really means a lot
    1:- Main goal of Spring framework is how to decouple relationship between dependent Object
    2:- Dependency Injection means separate the class which is dependent and inject them when its needed from outside.
    Perfect :) Thank you very much @kaushik

      thats what I learned from this video as well.
      Its about decoupling and delegating dependencies out of the class where it matters.
      The class itself doesnt know what happens and as soon as you need something to change you pass that info to the class from the outside.

    I have been browsing several articles/blogs/tutorials to understand Dependency Injection. And, this is one of the best I have come across that explains why one would need DI. I agree with others commenting that this is actually not about DI itself. Nevertheless it help me understand very clearly the need for DI. Thank you!! An "icing on the cake" for this video would be a summary graphic in end that can depict the "before" and "after".

      I really want to help you, being student the attitude always should be finding and digging for good.
      Question and Answers do not help.! If you have to gain maturity start asking yourself and search for it, evaluate the truth and adopt it as per the need.
      All frameworks do change continuously the way we need to follow for intention of doing program..
      Since from documentation of Spring there are many number of books on spring, each one talks in different context.
      There are many libraries even now a days all coming in digital world.! :) Thank you.
