tiens, c'est mon code qui compile (chez moi biensûr, je suis le seul à avoir les classes qui vont autour).
quand je marque que c'est à vous de mettre le code qui va bien autour, c'est pas pour rien, il y a une classe et 2 import minimum à mettre.
Sauf qu'on s'en fout de la compilation, je parle de naviguer dans le code source ! |
