Bonjour à tous,

alors je me lance dans l'apprentissage de Java à travers la création de plugins pour serveur minecraft Spigot.

Jusqu’à la tous allais bien j’avançais doucement mais je trouvais toujours solution dans la documentation JAVA et dans quelque petite recherche internet.

cependant je rencontre un problème dans la sauvegarde d'un fichier dans le qu'elle je stock une variable ArrayList (qui est bien sérialisable, oui j'ai vérifié).

Voici le code :

Code :

public class Main extends JavaPlugin {
 
	public ArrayList<Location> location = new  ArrayList<Location>() ;
 
	@Override
 
	public void onEnable() {
 
 
 
		//texte de console démarrage plugins
 
		System.out.println( "location : " + (new Location(null, 700,500,210)).toString());
 
		try {
 
			this.save("Test.tmp", new Location(null, 700,500,210));
 
		} catch (FileNotFoundException e) {
 
			System.out.println("erreur6");
 
			e.printStackTrace();
 
		} catch (IOException e) {
 
			System.out.println("erreur7");
 
			e.printStackTrace();
 
		}
 
 
 
		System.out.println("la méthode renvoir : " +  this.TestLocation("Test.tmp",new Location(null, 700,500,210)));
 
 
 
}

En gros quand démarre le serveur sa lance la methode save puis la méthode TestLocation que vous retrouver ci-après :

		System.out.println("3");
		FileInputStream fis = new FileInputStream("t.tmp");
		ObjectInputStream ois = new ObjectInputStream(fis);
		location = (ArrayList<Location>)ois.readObject();
		System.out.println("location");
		ois.close();
		return location;
	}
 
 
	public boolean TestLocation(String fileName,Location location){
		   this.location.clear();
		    try {
				this.location = this.load(fileName);
			} catch (ClassNotFoundException e) {
				System.out.println("eereur1");
				e.printStackTrace();
			} catch (IOException e) {
				System.out.println("erreur2");
				e.printStackTrace();
			}
		    if(this.location.contains(location)) {
		    	return true;
		    }
			return false;
	}

cependant dans la console j'ai que des erreurs ...

Pouvez vous m'aider a comprendre ses erreur et m'aider a les corrigés ? cela fais 2 jours que je cherche sans grande reussite.

Mon but final étant de sérialsié la variable location (qui est un ArrayList).



Merci pas avance si il y à des réponse.

Bien à vous,

Hello,

d'après ton code, cette ArrayList tu y mets des objets Location.

Maintenant que cette remarque est faite, est-ce que tu peux nous parler de cette ligne dans les logs d'erreur :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part
