Builder pattern vs. Dependency Injection (for instance via Guice)

Question

I\'m developing a simple tree-structured database and I\'m usually setting dependencies or optional settings via a Builder (Builder pattern). Now I\'m not sure when to use for i

Answer 1

I have started using builder for most of my projects and it turns out I can and have replaced all of my DI with builders and singleton.

ie:

AppContext appContext = new AppContext.Builder()
.setProperties(testProps)
.setDB(testDB)
.build();

// run tests

My code has become much simpler to manage without DI.
