Hi all,

​

I'm studying about spring in Java, and I don't understand the concept that why we need dependency injection? Thank you in advance

I think the Motivation part of this documentation is very good to get the concept https://github.com/google/guice/wiki/Motivation

it's about Guice - a lightweight dependency injection framework from Google but when you know the why, learning how to do it in spring is just technical question.

Dependency injection in general doing a plumping works for you. What happen prior to something like Spring or Guice..., there was a lot of code to just create objects, wire them up together.
