Why is importing a public class (Treet) necessary?

It is my understanding that public classes can be used outside of the package.

Public classes can still be accessed outside of the package, but you still need to import the Treet class file into your main class so that the Treet class file becomes visible to your main package.

The java complier will only automatically compile files in the same package - for classes in other packages, you need to import each file.
