Polymorphic question

Question

this is one of the questions for the java exam . i don't seem to understand the answer.
class SuperBase
    void print (SuperBase a)
        System.out.print("Super");
class Base extends SuperBase
    void print (Base b)
        System.out.print("Base");
class Derived extends Base
    static void print (Derived c)
        System.out.print("Derived");
public class Test {
    /** Creates a new instance of Test */
    public static void main (String args[])
        SuperBase a1 = new SuperBase();
        SuperBase b1 = new Base();
        Base c1 = new Derived();
        a1.print(new Base());
        b1.print(new Derived());
        c1.print(new Derived());
}the answer to this is super super base. i compiled and checked it.
I thought the answer would be super base base.
since b1 is a object type base with a reference variable of type superbase when the method is called at runtime i thought it would make a Polymorphic call the base method. therefore printing base for this call b1.print(new Derived());
I hope someone can explain why this is not the case. Thank you for your help.

Answer 1

sorry sujji i still don't get it.
i thought for example if you got a horse class which extends an animal class which both contain for example an eat method ie public void eat()
then
Animal a = new Animal();
Horse b = new Horse();
a.eat(); //runs animal version
b.eat(); // runs horse version
does this mean the base method is not overidding the SuperBase class print method but actually overloading it.
void print (SuperBase a) // in SuperBase class
void print (Base b)// in Base Class
if thats the case i understand, otherwise i am now completely lost.
