Assume that the following classes have been defined: 

public class Biggie extends JayZ {
    public void a() {
        System.out.print("Biggie a   ");
        super.a();
    }

    public String toString() {
        return "Biggie";
    }
}

public class JayZ extends Tupac {
    public void a() {
        System.out.print("JayZ a   ");
        b();
    }
}

public class FiftyCent extends Biggie {
    public void b() {
        System.out.print("FiftyCent b   ");
    }
}
public class Tupac {
    public void a() {
        System.out.print("Tupac a   ");
    }

    public void b() {
        System.out.print("Tupac b   ");
    }

    public String toString() {
        return "Tupac";
    }
}

Given the classes above, what output is produced by the following code? 

Tupac[] elements = {new Biggie(), new Tupac(), new JayZ(), new FiftyCent()};
for (int i = 0; i < elements.length; i++) {
    elements[i].a();
    System.out.println();
    elements[i].b();
    System.out.println();
    System.out.println(elements[i]);
    System.out.println();
}
elements[0]: Biggie
elements[1]: Tupac
elements[2]: JayZ
elements[3]: FiftyCent
