polymorphism without virtual methods

According to book SCJP Sun Certified Programmer for Java 6 Study Guide, "all java objects are polimorphic".

class B {} class A extends B {}

Class A doesn't have any overriden methods. Is it polymorphic ?

Definitely, because class B extends Object and Object has a few methods already.
