manipulating classes during runtime

[Timo Nentwig]

Hi!

Similar to reflection is it possible to manipulate classes on runtime, e.g.
adding methods and fields? AOP?

No.

It is however possible to create _new_ classes at runtime. Using a
specialized classloader you can perhaps get most of what you want.
Google to find helpful projects.

You also have the method Proxy class (java/1.3+) that can be used for
some interesting things.

If you care to tell us more about what you try to do we may be able
to provide more information.
