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 */
}
}
