Are you talking about level of inheritance?
Then no need to have the source file, instead you need Class files of all the dependent classes.
Now have a look at Class.
Then look at Class.getSuperC lass.

Have you read the API documentation for the Class class? Have a look at the very first article in this group; it contains a link to the API download site (from Sun). Download the API documentation and read it.

You're welcome of course; that API documentation is a must read and you should have it stored on your hard drive; without it you're in the dark. Look at the Object class first; it's the 'mother of all classes'. It has a getClass() method that gives you a Class object; it describes the class the particular object is instantiated from. Next look at the API documentation for the Class class; it can return another Class object that represents the super class of the current class if any; otherwise it returns null. That is the building block for what you want to calculate.

There's hardly any code to write because the File class does about all; have a look at the list() or listFiles() methods in that class.

First of all this is a different question, no relation with this thread.
Anyway for your solution, see File.listFiles.

Programmers who aren't comfortable with shells etc. are just junior programmers, too much influenced by a windows, graphical environment. Granted, the shell/cmd in Microsoft Windows isn't worth much but still ...

        System.out.println("Simple file listing...");
        System.out.println("----------------------");

        File dir = new File(dirName);
