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 ??
