Final method

Having said a final method can be overloaded(default in d same class) plz explain me if there is anything missing in this code ?

class Base {
public final doSomething(Object o) {
System.out.println("Object");
}
}
class Derived extends Base {
public doSomething(Integer i) {
System.out.println("Int");
}
}
public static void main(String[] args) {
Base b = new Base();
Base d = new Derived();
b.doSomething(new Integer(0));
d.doSomething(new Integer(0));
}
This will print:
Object
Object
MY DOUBT IS IN THE DERIVED CLASS METHOD ! IS DER D FINAL KEYWORD MISSING ??

No there is no coding mistake. Only there has to be return type for method doSomething() as void.

In the main method,you simply change the "base d" as "Derived d" you get "object" and "int" as a output.also returned type is required.
