Liste, tableau?

DiabolicaTrix

Bonjour! Mon titre n’est peut-être pas très clair donc je vais expliqué:

J’ai une liste de neufs permis et je dois les enregistrer dans mon extended entity properties pour pouvoir ensuite les lister. Donc au début, je me suis dit que j’allais créer 9 boolean et les mettres à true si il le possède, mais je ne pourrais pas faire de boucle for pour les lister. Ma deuxième solution, était d’utiliser un tableau pour le faire, ce n’était pas une mauvaise idée, mais j’ai un crash au moment de la synchronisation client/serveur. Ensuite, Julot m’a proposé d’utiliser une liste mais je ne m’en suis jamais servi donc je n’ai aucune idée comment ça fonctionne.

Quelle serait selon vous la meilleur méthode?

Ensuite viens le problème de l’identification, je dois les lister, mais il faut que ce soit propre, dans le sens qu’ils doivent avoir un nom localisé, encore là je ne connais pas la meilleure façon de le faire

Plusieurs boolean = pas une bonne idée.
Ensuite pour la question liste ou tableau c’est simple.
Si la taille est fixe → tableau.
Si la taille est variable → liste.

DiabolicaTrix

La dimension n’est pas variable.

Que veux-tu dire pas une bonne idée?

robin4002

Car pour les listes ça va être plus compliqué.

Que tu utilises un tableau ou plusieurs boolean, si ça crash c’est pas la structure de données qui est foireuse, c’est ton code.
Créer plusieurs boolean n’est pas une bonne idée, car d’un point de vue programmation tu ne pourra pas faire de boucle, tu ne pourra pas retourner l’ensemble de tes permis via un getter etc… Bref, ça t’impose énormément de limite. D’un point de vue JVM, tu fragmentes la mémoire inutilement.

Un tableau c’est bien si tu connais d’avance sa taille.
Une List, se décompose en 2 implémentations : l’ArrayList et la LinkedList.
Une ArrayList se base sur un tableau dont la taille est multiplié par 2 dès qu’un ajout dépasse le nombre de case.
Une LinkedList c’est une chaine d’élément. C’est a dire que l’élément 1 possède un lien vers l’élément 0 et l’élément 2 etc…

ArrayList ou LinkedList ? ça dépend :

Si tu veux accédez a l’élément i et qu’il est au milieu de ta liste

ArrayList : Tu peux y accéder directement.
LinkedList : Tu dois parcourir la moitié de ta liste.

Si tu ajoute un élément à la moitié de ta liste (idem pour la suppression)

ArrayList : Tu recopies les éléments suivant a la case n+1, un par un.
LinkedList : Tu insert directement l’élément en modifiant juste le chainage

En gros :

Structure de donnée : Accès random / Modification
ArrayList : +++ / +
LinkedList : + / +++

En fait, la taille n’est pas variable dans je n’ai techniquement pas besoin d’une liste sinon, mon code crashait au niveau de mon buf.readBoolean(); car en fait j’utilisait un boucle pour parcourir le tableau et buf chacun de mes valeurs, mais je crois que pour le récupérer je dois utiliser une boucle pour les récupérer un par un?

Bref, je crois que l’utilisation d’un tableau serait moins complexe et je vais réessayer et renvoyer le crash si il y en a un.

Sinon, un autre problème dont je n’ai aucune idée, comment je pourrais récupérer le nom de la valeur en fait, il me faudrait un nom localisé pour chaque permis et lister les permis qu’il possède.

EDIT: J’ai fait un système avec des tableau et cette façon m’a semblé la meilleure mais je dois avoir fait une erreur.

Le crash:

Tu dois initialiser ton tableau

Deleted

Il est initialisé son tableau, regarde sa variable licenses

robin4002

Non.

private boolean[] licenses;

licenses est null.

Cette variable n’est que initialisé dans le constructeur utilisé pour l’envoie du paquet :

public PacketRestrainServer(boolean restrained, long cash, long money, boolean escorted, boolean[] licenses) {
this.restrained = restrained;
this.cash = cash;
this.money = money;
this.escorted = escorted;
this.licenses = licenses;
}

Dans le constructeur utilisé à l’arrivé du paquet, il n’y a rien :

public PacketRestrainServer() {}

Pour la gestion des noms, afin d’éviter de faire un tableau avec des booleans et un autre avec des Strings pour le nom non localisé, ce que je ferai c’est utiliser un seul tableau. Seulement celui avec les strings et j’utiliserai un string null (ou un qui vaut “”) pour l’équivalent de false, dans les autres cas true.

Deleted

A oui mal vu…
Au pire, si il l avait initialisé en même temps que la déclaration y aurait pas eu ce genre de soucis ^^’

DiabolicaTrix

Pour les nom localisé, c’est une bonne idée, par contre pour le reste normalement je ne crois pas que le fait qu’il soit null cause un problème car elles le sont toutes et je n’ai pas de problème.

private boolean restrained;
private long money;
private long cash;
private boolean isMoney;
private boolean escorted;

private boolean[] licenses;

Sinon, je n’ai pas trop compris, tu veux que je mettes quoi dans l’arrivée du packet?

robin4002

Tu utilises le field length du tableau licences, or comme licences est null ça cause un NPE.

DiabolicaTrix

Ah d’accord, je dois donc l’initialisé là à la place du constructeur.

Résolu Liste, tableau?
