List<String> not working...

this is my code:

Code:

ArrayList<String> toCensore = new ArrayList<String>();
toCensore.add("string");

but the toCensore.add("string"); is underline in red.
i've import:

Code:

import java.util.Collection;
import java.util.List;
import java.util.ArrayList;

 

Moved to a more appropriate section.

 

@mariusvnh What is the error message?

but the lines of the error are toCensure.add("string");

 

@mariusvnh
Please post your entire Code.
As well as what the error message in your IDE is saying (The message that gets displayed when you hover over the red underlined text)

 

Code:

package be.drgeek.midiacraft;

import java.util.Collection;
import java.util.List;
import java.util.ArrayList;
import org.bukkit.event.Listener;
import org.bukkit.event.EventHandler;
import org.bukkit.event.player.AsyncPlayerChatEvent;
import org.bukkit.entity.Player;

public class midiacraftChat implements Listener{
    midiacraftPlugin plugin;
    midiacraftCommands listener;
    //midiacraftPlugin listener1;
    ArrayList<String> toCensore = new ArrayList<String>();
    toCensore.add("string");
  
    public void ChatListener(midiacraftPlugin plugin){
        this.plugin = plugin;
    }
  
  
    @EventHandler
    public void onPlayerChat(AsyncPlayerChatEvent event){
        Player p = event.getPlayer();
        String msg = event.getMessage().toLowerCase();
        for(int i = 0; i < toCensore.size(); i++){
            if(msg.contains(toCensore.get(i))){
                p.sendMessage(String.format("§cCe mot n'est pas autorisé : %s", toCensore.get(i)));
                event.setCancelled(true);
            }
        }
    }
  
}

 

@mariusvnh
Please tag me otherwise I might not see your post.
And you cant add an Item to a List in the class itself. You have to do it in a constructor or method etc...
Simply include the adding of the string into your Constructor and you are good to go.

 

yes but i want to create a command :

Code:

package be.drgeek.midiacraft;

import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerCommandPreprocessEvent;

public class midiacraftCommands implements Listener {
    midiacraftChat chat;

    @EventHandler(priority=EventPriority.MONITOR)
    private void onPlayerCommnandPreprocess(PlayerCommandPreprocessEvent msge){
     
        Player p = msge.getPlayer();
        String msg = msge.getMessage();
     
        String[] args = msg.split(" ");
        if(args[0].equalsIgnoreCase("/censure")&&p.hasPermission("midiacraft.CanAddCensure")){
            chat.toCensore.add(args[1]);
            p.sendMessage(ChatColor.GREEN + String.format("Le mot %s a été banni du chat.", args[1]));
            msge.setCancelled(true);
        }
    }
 
 
}

in a different class

 

@mariusvnh
Please tag me otherwise I might not see your post.


It has nothing to do with the command. It's simply how Java works. You cannot call methods outside from a constructor/method/etc...
Adding it from within the Command will work since it is a method.
But your over Code runs outside from anything.

 

@mrCookieSlime
soory for the tag
thaks for the info
but the command, i don't know why it not works

 

@mariusvnh
Did you register your Listener?
What does it do when you execute the Command?
What command are you executing?

 

@mrCookieSlime
i use the command /censure [word to censure]
yes i register my listener
it say "type /help ..."
and my console say:

 

@mariusvnh
But you still did not post the needed Code...
Please post your midiacraftlistener.class and your onEnable method.

 

@mrCookieSlime
but there's nothing about the censure in this file:

Code:

package be.drgeek.midiacraft;

import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.event.player.PlayerQuitEvent;
//import org.bukkit.event.block.SignChangeEvent;

public class midiacraftListener implements Listener {
   
   
    @EventHandler(priority = EventPriority.MONITOR)
    public void playerConnectEvent(PlayerJoinEvent e)
    {
        Player p = e.getPlayer();
        String connectMessage = midiacraftPlugin.plugin.getConfig().getString("connect-message").replace(".ply.", p.getName());
       
        e.setJoinMessage(ChatColor.YELLOW + connectMessage);
       
    }
    @EventHandler(priority = EventPriority.MONITOR)
    public void PlayerDisconnect(PlayerQuitEvent e)
    {
        Player p = e.getPlayer();
        String disconnectMessage = midiacraftPlugin.plugin.getConfig().getString("disconnect-message").replace(".ply.", p.getName());
       
        e.setQuitMessage(ChatColor.RED + disconnectMessage);
       
       
    }
   
}

 

@mariusvnh
Indeed. But your Error leads to that file.
And I still need your main class.

 

@mrCookieSlime
all my files:
midiacraftPlugin (main) :

Code:

package be.drgeek.midiacraft;

import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.plugin.PluginManager;




public class midiacraftPlugin extends JavaPlugin /*implements Listener*/{
    public static midiacraftPlugin plugin;
    midiacraftChat listener;
    //midiacraftChat plugin2;
    @Override
    public void onEnable(){
        PluginManager pm = getServer().getPluginManager();
        pm.registerEvents(new midiacraftCommands(), this);
        pm.registerEvents(new midiacraftListener(), this);
        pm.registerEvents(new midiacraftChat(), this);
       
       
       
        plugin = this;
        saveDefaultConfig();
        getLogger().info("Plugin Midiacraft Démarré");
    }
    public void onDisable(){
        plugin = null;
    }
   
}

midiacraftListener :

Code:

package be.drgeek.midiacraft;

    {
        Player p = e.getPlayer();
        String connectMessage = midiacraftPlugin.plugin.getConfig().getString("connect-message").replace(".ply.", p.getName());
       
        e.setJoinMessage(ChatColor.YELLOW + connectMessage);
       
    }
    @EventHandler(priority = EventPriority.MONITOR)
    public void PlayerDisconnect(PlayerQuitEvent e)
    {
        Player p = e.getPlayer();
        String disconnectMessage = midiacraftPlugin.plugin.getConfig().getString("disconnect-message").replace(".ply.", p.getName());
       
        e.setQuitMessage(ChatColor.RED + disconnectMessage);
       
       
    }
   
    /*@EventHandler(priority = EventPriority.LOWEST)
    public void onSignChange(SignChangeEvent event){
        if (event.getLine(0).equalsIgnoreCase("[marius]")){
            event.setLine(0, "test");
        }
    }*/
   
}

midiacraftCommands:

Code:

import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerCommandPreprocessEvent;

public class midiacraftCommands implements Listener {
    midiacraftChat chat;
   
    //private midiacraftPlugin plugin;
   
    @EventHandler(priority=EventPriority.MONITOR)
    private void onPlayerCommnandPreprocess(PlayerCommandPreprocessEvent msge){
       
        Player p = msge.getPlayer();
        String msg = msge.getMessage();
       
        String[] args = msg.split(" ");
        if (args[0].equalsIgnoreCase("/midia") && args[1].equalsIgnoreCase("infos")) {
            p.sendMessage(ChatColor.BLUE + "Plugin du serveur MidiaCraft");
            p.sendMessage(ChatColor.BLUE + "Créé par mrcoupobol (DrGEEK)");
            p.sendMessage(ChatColor.BLUE + "v0.1");
            msge.setCancelled(true);
           
           
        }
       
        if(args[0].equalsIgnoreCase("/censure")&&p.hasPermission("midiacraft.CanAddCensure")){
            chat.toCensore.add(args[1]);
            p.sendMessage(ChatColor.GREEN + String.format("Le mot %s a été banni du chat.", args[1]));
            msge.setCancelled(true);
        }
       
        if(args[0].equalsIgnoreCase("/adminmsg")){
            p.sendMessage(ChatColor.RED + "Commande INDEV");
            msge.setCancelled(true);
           
        }
    }
   
   
}

and midiacraftChat:

Code:

package be.drgeek.midiacraft;

//import java.util.Collection;
//import java.util.List;
import java.util.ArrayList;
import org.bukkit.event.Listener;
import org.bukkit.event.EventHandler;
import org.bukkit.event.player.AsyncPlayerChatEvent;
import org.bukkit.entity.Player;

public class midiacraftChat implements Listener{
    midiacraftPlugin plugin;
    midiacraftCommands listener;
    ArrayList<String> toCensore = new ArrayList<String>();

   
    public void ChatListener(midiacraftPlugin plugin){
        this.plugin = plugin;
    }
   
   
    @EventHandler
    public void onPlayerChat(AsyncPlayerChatEvent event){
        Player p = event.getPlayer();
        String msg = event.getMessage().toLowerCase();
        for(int i = 0; i < toCensore.size(); i++){
            if(msg.contains(toCensore.get(i))){
                p.sendMessage(String.format("§cCe mot n'est pas autorisé : %s", toCensore.get(i)));
                event.setCancelled(true);
            }
        }
    }
   
}

 

@mariusvnh
The Variable chat is null in midiacraftCommands.
You probably want to set the variable to an instance of midiacraftChat. You can do that using your constructor.

 

@mrCookieSlime
but ... what is a constructor?
i'm a begineer

 

@mariusvnh
http://docs.oracle.com/javase/tutorial/java/javaOO/constructors.html

example for your case:
Awesome awesome = new Awesome(this);
pm.registerEvents(awesome, this);
pm.registerEvents(new Cool(awesome), this);

You can figure out the rest and what that means after reading the article I sent.

 

thanks
