Java instance of a class from a string

Question

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 create an instance of C , but I seem to get 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(). superb.doWork(); 

Answer 1

The only thing I can think of is that you did not redefine doWork () in C.

Perhaps you tried to cancel, but with some spelling error in the method name or incorrect parameters?

Answer 2

Assuming you are using a newer version of Java, add @Override to the doWork method. If you override the method incorrectly, the compiler will inform you of this.

Answer 3

Are you sure C overrides the doWork method? Based on the question posed, it is quite reasonable / legal to expect that, within the framework of the extension, B C does not provide its own implementation for doWork and instead relies on the one that was provided to superclass B

Answer 4

I see the result:

A do work

what do you expect
