final keyword Method local inner class

[Kasak Tahilramani]

final keyword in method local inner class:

Is I declare my method-local inner class as final,I cannot instantiate it then how can I access method of it ?

public class HHH
{

public static int sampleMethod()
{
final class AC {
int m(){
return 0;}
}

class CC {
int m() {
return 42;
}
}


AC c = new AC();
// cannot instantiate final class then how can I instantiate in method local //class.Is it valid to do ?
return c.m();

}

public static void main(String[] args) {
System.out.println(sampleMethod());
}
}

There would be no problem if you would have

AC c = new AC();

or

CC c = new CC();

Hi there

AC c = new CC(); is not permitted in your example.

Change it to :
AC c = new AC();

it will then work.

There is nothing unusual here. CC is not an AC so you cannot assign it to a reference variable of type AC. CC cannot extend AC because AC is final. This is nothing special to do with method local inner classes.

Thank all .But I had edited the post so please correct where I am going wrong.

[Anton Uwe]

Did you compile and run your code? If not, why not?
If yes, what exactly is your question?

Edit:

// cannot instantiate final class then...

Perhaps you just mixed up "final" and "abstract"?

Thanks Anton.I tried running my code and it is working fine.Appreciate for your help.

But one question that is bothering me is that,If I cannot instantiate a normal final class, how I am able to do it with method-local class which is final.

[Anton Uwe]

If I cannot instantiate a normal final class, how...

There really is no problem to instantiate a normal final class. You have done it already, for sure, if you ever used String, or Integer, other wrappers, and so on. I still believe you perhaps mix up final and abstract.
