Every class extends object but why it is not possible for
every object to invoke clone() method. ideally protected
methods should be accessible from sub classes. isn't it?

Answer / aslam
Since the method is protected we can access clone method
only within the package or from subclasses outside the
package.
for ex:
class A{
public static void main(String arg[]){
new A().clone();
/* This is legal since class A is a subclass of Object and
we r accessing within the subclass*/
}
}
class B{
public static void main(String arg[]){
new A().clone();
/* Illegal since we r accessing it from outside object */
}
}

clone() method must be called on only cloneable objects so sub class must implement Cloneable marker interface
