Erreur "n must be positive" lors de la création d'un menu

ItsMeKam59

Bonjour,
J’ai une erreur lorsque je créé mon menu et que je lance le client.
J’ai ça :

Seriez-vous m’aider et me dire quelle est l’erreur ?

Cordialement,

PS : Si vous voulez les codes, je vous les fournis.</init></init>

Überfap

Les codes s’il te plaît Apparemment, il y a une valeur négative donnée par un random à la ligne 89 du GuiCustomMainMenu alors qu’elle devrait être positive

ItsMeKam59

Salut, merci de ta réponse.
C’est ça mon code de ligne 89


public GuiCustomMainMenu()
{
BufferedReader bufferedreader = null;
try
{
ArrayList arraylist = new ArrayList();
bufferedreader = new BufferedReader(new InputStreamReader(Minecraft.getMinecraft().getResourceManager().getResource(splashTexts).getInputStream(), Charsets.UTF_8));
String s;
while ((s = bufferedreader.readLine()) != null)
{

}
do
{
this.splashText = ((String)arraylist.get(rand.nextInt(arraylist.size())));
} while (this.splashText.hashCode() == 125780783);
}

Cordialement,

jglrxavpok

Il faut ajouter ta variable s à l’ArrayList, sinon la taille de cette liste est de 0 donc une valeur non positive (en maths anglais)

ItsMeKam59

Si je mets ça :


{
String s = s.trim();
if (!s.isEmpty()) {
arraylist.add(s);
}
}

Je dois renommer


string s

en s1
Cela renomme tout en s1
Mais après


s.trim();

J’ai cette erreur : “the local variable s1 may not have been initialized.”
je dois faire quoi?

Cordialement,

Überfap

Bah non tu fais String s1 = s.trim() et après tu fait arrayList.add(s1)

ItsMeKam59

Merci de ton aide

Überfap

Oh mais de rien Ravi de t’avoir aidé
