How can I use a int List from the Config?!

Hey guys,
I create a countdown command and a I create a config.yml.

example: /countdown 5 10 the server reload...
10 sec. later...
Remaining time until: the server reload...: 5
Remaining time until: the server reload...: 4
Remaining time until: the server reload...: 3
Remaining time until: the server reload...: 2
Remaining time until: the server reload...: 1
The Countdown has ended!


ok until here everything works fine,
but now I down't want the countdown to Broadcast every sec.
he shold ownly count specific numbers like for example: 120,60,30,20,10,5,4,3,2,1 and not fill up the whole chat.
These numbers should be set in the config.yml like this:

How I do this!?
and I have another question:
If I'm finish with this problem I want to do the command this
example: /countdown 5 10 the server reload... /reload
is this posible that a command can callup a other command!?

Thank you in advance for reply

 

How can I make this List?
And how can I put the numbers from the Config into this list

 

Config

 

Like this?

List<Integer> countdownlist= plugin.getconfig().getIntegerList("Config.messages.countdown");

 

okay and how can I use this list now in my command? sry I'm relativly new in java/bukkit...

 

I tried this:
List<Integer> countdownlist = plugin.getConfig().getIntegerList("Config.messages.countdown");
Bukkit.broadcastMessage("Countdownlist:" + countdownlist.get(2));

Config

Code:

Config:
  messages:
    countdown: 120,60,30,15,10,5,4,3,2,1

and when I tried the command there comes this:

ok and what can I do about it?

 

Code:

public class TimedEvents extends JavaPlugin
{
    private static TimedEvents plugin;

    public void onEnable()
    {
        plugin = this;
        loadConfig();

        getCommand( "countdown").setExecutor(new CountdownCommand());
        getCommand( "qcountdown").setExecutor(new QCountdownCommand());
        //getCommand( "delay").setExecutor(new DelayCommand());

        this.printPlugin("§aEnabled");
    }

    public void onDisable()
    {


        this.printPlugin("§cDisabled");
    }
    private void printPlugin(String m)
    {
        String pcolor = getConfig().getString("Config.messages.plugincolor");
        final String pluginName = "§7[§" + pcolor /*getConfig().getString("Config.messages.plugincolor")*/ + "TimedEvents§7]: ";
        Bukkit.getConsoleSender().sendMessage(pluginName + m);
    }
    public static TimedEvents getPlugin()
    {
        return plugin;
    }

    public void loadConfig()
    {
        getConfig().options().copyDefaults(true);
        saveConfig();
    }

}

Code:

    public QCountdownCommand(TimedEvents main)
    {
        this.plugin = main;
    }
