Hi, I got the following exception when running the codes attached below:
Exception in thread "main" java.lang.InstantiationException: IFactory$1
at java.lang.Class.newInstance0(Class.java:281)
at java.lang.Class.newInstance(Class.java:249)
at IFactory.getI(IFactory.java:20)
at IFactory.main(IFactory.java:35)
Is it because Java doesn't support reflection for anonymous inner class? If
so, how can I have dynamic classes? Is it possible?
Thanks in advance.

Does this have anything to do the famous reflection error, you must have a
default public constructor, in order to use class.newInstance() method.

it does'nt make sense. anonym. inner class needs access to parent object, even
local variables, how could it be created outside the scope it is defined.
use static public nested class.

IMO,this problem is caused by that any non-static inner class does
not have a default constructor(i.e. an argumentless one).
They always have a constructor that takes a reference to the
enclosing instance.
There is no way you can do the thing you are trying to
do in the way you are doing it now. 8-) I think you are doing things
in Java with some COM mentality. Dynamic Proxy is probably what
you are looking for...
