Java Java Data Structures Getting There Packages

"com" and "teamtreehouse" folders are packages?

So, in this video we created two folders: one called "com", and the other called "teamtreehouse" (which this latter one contained the Treet.java file).

Are the "com" and "teamtreehouse" folders actually considered "packages"? And ultimately, are all folders that contain .java files technically "packages" going forward?

Indeed they are! The compiler will use the folder structure to try to find the class you are referring to. Packages, like folders provide you the ability to have the same named files in different categorized places.

So there are other ways to include packages, as you'll notice the stuff we are importing aren't there in your directory. You can package up folders and include them like a zip file, but it's called JAR file (Java ARchive). But those folders in the "zip" file are also the package levels.

That make sense?
