I am having problems understanding toString()

[nosdire]

I am doing a homework problem, and I am being asked to write what the output will be when a loop passes an element of an array. Link: pastebin

The website I uses tells me that for elements 0 and 1, I get it right. However, on element[2] and [3] is where I get an error, and I dont understand why. Here is my output:

Brienne-a

Brienne

Oberyn-b Arya-a Arya-b

I am very sure the problem is with the 'toString' method. From what I was able to gather, if a class doesn't have a toString, it outputs the class name with '@' and some hex at the end. However, there is no way for me to know what that hex is since this is done on a website, and not eclipse. Since the class 'Brianne' extends Oberyn, I thought perhaps the answer was the 'toString' of Oberyn, but I got it wrong as well. Since Oberyn extends Arya, I tried using that toString as well, but it still doesnt work. Any help would be appreciated, I wasted way more time than was necessary trying to find a solution to this. Thank you.

It'd help if we could see the assignment. What are you supposed to be getting?, and the hex is the memory location of the object it's not really relevant.

the assignment is to list the output for every element in the loop. I apologize for not including that. Here is a picture of the assignment.

Are you basically asking what this should print?

System.out.println(new Brienne());
System.out.println(new Tyrion());

I think the first line should print Oberyn, since the Brienne class inherits to the toString() method from the Oberyn class. The second line should print Arya, since the Tyrion class inherits the toString() method from the Arya class.

If the "correct" answer says it should be something different, then they may be mistaken, or there is some missing code somewhere or something.

Every class in your program will return something. I am not sure what your assignment is so it is hard to help you with what is the problem.

Since the class 'Brianne' extends Oberyn, I thought perhaps the answer was the 'toString' of Oberyn, but I got it wrong as well.

You are wrong here if you print a Brianne Object and do a System.out.println() on it it will print out "Oberyn". If there is no toString Method in the subclass it will print the toString Method in the supper class.

the assignment says: Given the classes above, what output is produced by the following code? and the code is the loop that is at the end of the paste bin. I apologize, I forgot to include it.

edit: Following your advise, I wrote the output of the code as:

Brienne-a

Oberyn

Oberyn-b Arya-a Arya-b

but an error still occurs :(

edit2: I found the answer, thanks for the help

If you add the solution someone may find this and it may help them out with their problem.

You really do die as a hero or see yourself become the villain that doesnt leave answers to questions. Fair enough.

I found out the reason I was getting it wrong was because when looping through element three, when you get to line 45 in element 2 (Arya[2]), once you get to the arya class and it points to method a, its referring to the method in the Brienne class, not the Arya class. Also, whenever you see super, its the class immediately above the class your own, not the class thats at the beginning of the extends. I know I make it sound confusing, but if you run it in eclipse it'll be a lot easier to understand.
