In Java, is there any way to use the JDK libraries to discover the private classes implemented within another class? Or do I need so use something like asm?

2. Java reflection: How can I retrieve anonymous inner classes?    stackoverflow.com

I have an anonymous inner class inside another class (SomeClass). Both SomeClass.class.getClasses() and SomeClass.class.getDeclaredClasses() return empty arrays. I couldn't find some hints on this in Class' Javadocs. Can anonymous inner classes be retrieved using ...

8. reflection of static inner classes    coderanch.com

You mentioned the method in an erroneous example. I mentioned the method as the answer. You seem to be confusing "nested classes" with "inner classes". There is no such thing as a "static inner class". In fact, the only difference between a nested class and an inner class is that an inner class must be non-static (Java Language Specification 8.1.2). Try ...

9. How to access private method of an inner class using reflection.    forums.oracle.com

Thanks, but i guess this will be used once we get the method or field object and I want to know how can i get the "Method object" for the inner class private method, like the way i get it from getDeclaredMethod() of Class.

10. Creating a private inner class using reflection    forums.oracle.com

Either use dynamic proxies (google is your friend) which will allow you to generate a class at runtime which implements any interface(s) you need, or, if it's for actual testing (rather than just trying stuff out) you might be interested in a mock objects framework, such as EasyMock. On the subject of dynamic proxies, libraries like CGLIB and ASM will allow ...
