If you''re simply looking to save a class file to the hard drive, take a look at serialization:

http://java.sun.com/docs/books/tutorial/essential/io/serialization.html

Serialization allows you to write data from a class file such that you can later reconstruct the object. Here''s an example of how to save an object:

  
MyClass mclass = new MyClass();

FileOutputStream out = new FileOutputStream("datafile");
ObjectOutputStream str = new ObjectOutputStream(out);
str.writeObject(mclass);
str.flush();
