8 errors

and im gettin 8 error messages

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

i havent created it yet. so do u think when ive created tht program it will sort my other program out?

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.
