Why are both Systemizer and Karaoke built in com.treehouse? I am trying to figure out what com.treehouse is. Does that mean that they are both housed in it? I hope my question is not confused, but I was thinking that is Karaoke is a new project, why does it now have it's own new folder that is not com.treehouse?

Any time your start a project in Java (maven or gradel) you should assign a workspace for your project to avoid name collision.

14,132 PointsHello
Let try a simple every day analogy.
You are going to the store to but a can of tuna, and may some chip and , not to miss, a loaf of bread. You told your neighbor and he said ... wow man, buy same thing.
you go to the store and upon check out, you put your can of tuna, your chips and your loaf of bread in one bag. You label this bag com.mybag
then you take his can of tuna, his chips and his loaf of bread in one bag in a different bag and you label it com.hisbag.
now even though both bags contains same items (same code names), they can certainly identify which belong to you and which belongs to him
Packaging is not a Java thing ... it is a coding thing. It is in C#, Java, Python and you name it. to package related code in package to avoid name collision and to clearly identify which code (tuna can) you want to use in your code; and remember, the two example tuna cans have same name (same program name), but the tuna inside is not same ....
Hope this help clarify the concept.

Front End Web Development Techdegree Graduate 17,305 PointsThanks for the analogy Mark, and which exactly get’s back to my point on why the Karaoke and Systemizer modules both use com.treehouse. Here I am assuming that com.treehouse is the bag in the analogy, and almost assuming that if Karaoke is in com.treehouse, then Systemizer should be in let’s say com.treemansion?
