What is & Why Dependency Injection (DI)?

Classes specify what their dependencies are NOT how to obtain them
- “How to obtain” is now handled by the container
Why Dependency injection?
- Dependency injection makes unit-testing and mocking easier
- Dependency injection allows container to do the bean-discovery and bean-wiring
Dependency Injection frameworks (containers)
- Spring
- Guice
- Seam
- EJB 3.x
- CDI (the latest, the best, and standard-based)

Thank you very much, so much information, but I really learned a lot. The labs are really great, I'll keep going back to those in the future.

Thank you for the seminar. It was a lot of information in few days, so good job. I'm gonna recommend jpassion.com to my friends.

Daniel C.

The most useful programming course I have ever attended!

Omar N. S.

These seminars are covering more than just what the topics are. In many cases, the students ask questions and Sang demonstrates how to do something with the IDE or browser that we can use in all of our programming tasks even outside the class. It's a great way to learn!!

John S.

Thank you for running this course. The combination of online tutorials and exercises is very well put together and an excellent way of learning or refreshing a technology. The code camp builds on this: Sang is a great teacher and was very helpful at answering all our questions.

Michael R.

Nobody can teach you better Java (JVM) related courses than Sir Sang Shin. He is a true master.
