Instructor: Let's take care

of our normal housekeeping work.

Let's stop all apps and close all windows.

And now I'll go ahead and do a copy, paste here

on our 03 setter injection

and then I'll rename it as 04 qualifiers.

And then I'll go ahead and open this project in IntelliJ.

I'll go ahead and do a rebuild project just to make sure all

of our auto loading will work accordingly.

And then let's go ahead and move into our demo controller.

I'll expand the window here for a second.

And what I'd like to do is I'd like

to change the code back to make use

of constructor injection.

All righty, that's great.

So we have constructor injection set up, a okay.

Now I'd like to go through

and create multiple implementations

of the coach interface

just so we can kind of test this all out.

I'll move into this common package here

and I'll create a new class.

And this new class is called Baseball Coach

and this Baseball Coach implements, coach.

And I also add the component annotation on this class.

And then I'll go ahead and return a given string here

for the daily workout.

I'll tell the person to spend 30 minutes

in batting practice.

And now let's repeat the process here.

I'll create a new class here for Tennis Coach.

Implements the coach interface.

I'll also annotate this class with component.

And for Tennis Coach here,

we'll say practice your backhand volley.

All right, and let's repeat the drill one more time here.

Let's create a new class

and this will be for our Track Coach.

The Track Coach implements the coach interface

and the track coach, pretty intense, run a hard 5k.
