Alors voilà. Je veux réaliser un applet faisant appel à plusieurs classes.
Mon but est de faire une map.
J'ai une première classe nommée AppletJeu dans laquelle il y a un init(). Elle fait appel à la classe carte.class. Et c'est justement avec celle ci que j'ai des problemes. Je voudrais faire une connexion à mysql, récuperer une valeur pour l'attribut "M", et selon qu'il vaut 1 ou 2, afficher deux map différentes. Mais voilà, si je mets un init() dans cette classe, l'applet m'affiche un carré blanc, comme si il n'avait pas attribué de valeur à mon cases[][] qui defini ma map. Et quand j'enlève ce init(), impossible de me connecter à la BDD... Je vous mets mon code, si quelqu'un peut m'aider, ça serait gentil... Merci O dieux du java...

/**
* Cette classe représente la carte de jeu

tu assignes une constante locale (le 'cases' définit dans le if) à ta variable d'instance 'cases' mais il est détruit à la sortie du if. Remplace la définition (dans les if et les elses) par le code suivant :

this.cases =  new int[][] {
