如何从另一个 class I Java 访问变量

Question

I made minecraft plugin which have afk function but I need when player left and is in AFK list remove them! So I made this

MyClass instance = new MyClass();

// Im getting the table like this

instance.MyTable

Which dont works because I have already and quit event that just set custom quit messsage so it is weird

So my code looks like this!

public class QuitEvent implements Listener{
    
    afkCommand instance = new afkCommand();
    
    @EventHandler
    public void onQuit(PlayerQuitEvent event) {
        Player player = event.getPlayer();
        
        event.setQuitMessage("");
        Bukkit.broadcastMessage(ChatColor.WHITE + "[" + ChatColor.RED + "-" + ChatColor.WHITE + "] " + ChatColor.YELLOW + player.getDisplayName() + " has disconnected!");
        if (instance.AFK_Players.contains(event.getPlayer().getDisplayName())) {
            instance.AFK_Players.remove(event.getPlayer().getDisplayName());
            Bukkit.getConsoleSender().sendMessage("[Pixeluted Surival] " + event.getPlayer().getDisplayName() + " has been removed from AFK list because of quit!");
        }
    }
}

Also please correct me if Im wrong using this forum Im new to here! Thanks!

Answer 1

Well i don't know what your MyClass looks like or your MyTable . Judging off of first glance,First you need to add event handler within your constuctor to each object or item using it by creating an instance of listener eg

 QuitEvent handler = new QuitEvent(); object.addListener(handler);

Then add the first code snippet you sent in your main class method. Plus i don't know if you are implementing actionlistener or listener but which ever the case make sure to import the classes you are implementing into your constructor class.

I fixed it by setting the variable to static and used diffrent type of accesing it! Thanks for all responds!
