Good morning! (I'm in Switzerland :-))

This morning I'm confused about the book of Kathy&Bert...

In the self exam for the 3rd chapter on the 10th question it say's in answer:

References variables can live on the stack or on the heap and I believed that references variables lived only on the heap... Not?

Thanks for help... And sorry for my bad english

Bonjour,

Est-ce que tu peut envoyer le question entier? J'ai du mal a comprendre le question.

>References variables can live on the stack or on the heap and I believed >that references variables lived only on the heap... Not?

Last night I did some of chapter two in the same book. She mentioned that with method local reference variables, the OBJECT lives on the heap but the REFERENCE always exists on the stack. Maybe that's what she means, although I can't say for sure.

Moi, je suis a Paris. Ca fait du bien de parler en angalais et francais en meme temps

Anyways, if you send the entire question I think you'll find the correct solution.

have a nice day

Graham

Great!!!

R�ponse de la question 10 du chapitre 3:
When an object has a reference variable, the reference variable lives inside the object, on the heap.

Et la donn�e qui est dite comme correcte:
Some reference variables live on the stack, and some live on the heap.

Je croyais que tous les objets �taient dans le heap! Et c'est pas ce que dit la donn�e non?

I believed that references variables lived only on the heap

Merci c'est cool de pouvoir parler francais!

Reference variables can both live on the stack an on the heap. When you instantiate an object in a method, reference variable lives on the stack, but the object itself can have references to other ojects and then these references live on the heap.

Bonjour,

je pense que c'est meilleur de parler en anglais parce que plus de ranchers comprend ca. En plus, je crois que l'examen sera en anglais...

The variables local to a method live on the stack, while object variables (ie. fields of the object) are stored together with the object, which is on the heap. In both cases, you can have reference variables, so reference variables can both be stored on the stack and on the heap.

Regards,
Tilo
