Java.util.ArrayList cannot be cast to org.bukkit.World

Hi, I have a problem.
Booting or reloading my Minecraft server is no problem but when I type in this special command I get an errorcode in the console:



Here are my Classes:
Main:




Plugin.yml:


And my class with the command:

Code:

package de.justfrozen.advtools.cmds;


import org.bukkit.Bukkit;
import org.bukkit.World;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

public class TimeSet implements CommandExecutor {

    @Override
    public boolean onCommand(CommandSender s, Command cmd, String label, String[] args) {
        if(s instanceof Player) {
            World w = (World) Bukkit.getServer().getWorlds();
            Player p = (Player) s;
        
            if(p.hasPermission("advtools.timeset")) {
                if(args.length == 1) {
                
                    if(args[0].equalsIgnoreCase("morning")) {
                        p.sendMessage("§6Zeit wurde auf §c24000 §6gestellt");
                        w.setTime(24000L);
                        w.getTime();
                    
                    }else if(args[0].equalsIgnoreCase("day")) {
                        p.sendMessage("§6Zeit wurde auf §c6000 §6gestellt");
                        w.setTime(6000L);
                    
                    }else if(args[0].equalsIgnoreCase("evening")) {
                        p.sendMessage("§6Zeit wurde auf §c12000 §6gestellt");
                        w.setTime(12000L);
                    
                    }else if(args[0].equalsIgnoreCase("night")) {
                        p.sendMessage("§6Zeit wurde auf §c18000 §6gestellt");
                        w.setTime(18000L);
                    
                    }else
                        p.sendMessage("§7/w §6<clear:sun:rain:thunder>");
                
                }else
                    p.sendMessage("§7/w §6<clear:sun:rain:thunder>");
                
                } else
                    p.sendMessage("§cNicht genügend Rechte");
          
      
        } else
              s.sendMessage("In der Konsole nicht verfuegbar");
        return false;
}
}

There are no Errors in the code

 

This line is the problem, 'getWorlds()' returns an arraylist of worlds, not a world.

 

Thank you! Any ideas to fix the error now?
My goal is to control the time through commands in minecraft

 

@JustFrozen You could do 'Bukkit.getServer().getWorld("name_of_world");', then you could make the command specify the world with an argument and then get the world with the name of that argument, of course check if a world exists with that name.

 

Okay thank you, I'll try in a min

Thanks! it worked

@timtower
The world in which the player stands at the moment
