What is the difference between Strategy pattern and Dependency Injection?

Question

Strategy pattern and Dependency Injection both allow us to set / inject objects at run time. What is the difference between Strategy pattern and Dependency Injection?

Answer 1

Dude, dependency injection is a more general pattern, and it's about dependency on abstractions not concretions and it's a part of every pattern, but Strategy pattern is a solution to more specific problem

this is the definition from wikipedia:

DI:

Dependency injection (DI) in object-oriented computer programming is a design pattern with a core principle of separating behavior from dependency resolution. In other words: a technique for decoupling highly dependent software components.

Strategy Pattern:

In computer programming, the strategy pattern (also known as the policy pattern) is a particular software design pattern, whereby algorithms can be selected at runtime.

The strategy pattern is intended to provide a means to define a family of algorithms, encapsulate each one as an object, and make them interchangeable. The strategy pattern lets the algorithms vary independently from clients that use them.
