Dependency injection design pattern [duplicate]

What is dependency injection?
S开发者_开发百科pring uses dependency injection pattern. Can someone show a simple example of this pattern? I heard there is another pattern called service locator, which one is better?
Service locator is a J2EE "Core Patterns" idiom.
Let's define "better" before we debate it, shall we?
They aren't really competitors, IMO. Not every dependency happens over a network. Spring can do remoting and proxying, but that's not the sum of all dependencies.
