Java instantiate class from string

I have the following,

public interface SuperbInterface
public class A implements SuperbInterface
public class B extends A
public class C extends B

I want to instantiate C but I seems to be getting B, what did I do wrong?

Class classz = Class.forName("C");
SuperbInterface superb = (SuperbInterface)classz.newInstance();

//Here when I debug it seems to be going to B.doWork() methods instead of C.doWork开发者_如何学C().
superb.doWork();

The only thing I can think of is that you haven't overridden doWork() in C.

Maybe you have tried ot override but with some spelling mistake in method name or wrong parameters?

---

Assuming you are using a newer version of Java add @Override to the doWork method. If you have incorrectly overriden the method the compiler will then let you know.

---

Are you sure that C overrides the doWork method? Based on the question as it is posed it is perfectly reasonable/legal to expect that as part of extending B, C does not provide its own implementation for doWork and instead relies on the one provided the superclass B.

---

I see the outcome:

A's do work

whats the things you are expecting ?
