inheritance

[shruti1210]

Is the following code snippet show valid inheritance?

class A {
int v;
final String sayHello() {
return "Hello";
}
}
class B extends A {
public int sayHello(int a) {
return 3 + a;
}
}

It is valid code.
Class B will inherit v and String sayHello(), but nothing in the code makes use of that.

But String sayHello() is declared final which can not be overloaded...

Yes, but B doesn't try to do anything with that method.
sayHello(int a) is a different method signature from sayHello(); they are two completely different methods.
