    I don't see anything wrong with that code. Have you tried a clean re-build of your project? This is sometimes the problem (especially in Eclipse). Could you post the exact compile error you are getting?

    Does your Directory class know about the class DirectoryTest? eg are they in the same package? If not you need to import the DirectoryTest class

    All of the "DirectoryTest" errors are because there is no DirectoryTest class. Also, in your class you declared your array to be named StringList, but in all of your methods you access entries. Choose one or the other and stick with it.

    The compiler must know about everything, so if you haven't created the class yet there's the problem. Once you've created the class and defined its methods used in Directory those errors should disappear.
