Language$/$Type: Java inheritance polymorphism

Assume that the following classes have been defined:

public class Brienne extends Oberyn $\{$

public void a$()\{$

System.out.print$("$Brienne$-$a $")$;

$\}$

$\}$

$$

public class Arya $\{$

public void a$()\{$

System.out.print$("$Arya$-$a $")$;

$\}$

$$

public void b$()\{$

a$()$;

System.out.print$("$Arya$-$b $")$;

$\}$

$$

public String toString$()\{$

return "Arya";

$\}$

$\}$

$$

public class Tyrion extends Arya $\{$

public void a$()\{$

super.a$()$;

System.out.print$("$Tyrion$-$a $")$;

$\}$

$\}$

$$

public class Oberyn extends Arya $\{$

public void b$()\{$

System.out.print$("$Oberyn$-$b $")$;

super.b$()$;

$\}$

$$

public String toString$()\{$

return "Oberyn";

$\}$

$\}$

Given the classes above, what output is produced by the following code? $($Since the code loops over the elements of an array of objects, write the output produced as the loop passes over each element of the array separately.$)$

Arya$[]$ thrones $=\{$ new Oberyn$(),$ new Arya$(),$ new Brienne$(),$ new Tyrion$()\}$;

for $($int i $=0$; i $<$ thrones.length; i$++)\{$

thrones$[$i$].$a$()$;

System.out.println$()$;

System.out.println$($thrones$[$i$])$;

thrones$[$i$].$b$()$;

System.out.println$()$;

System.out.println$()$;

$\}$
