Timer stopping

Hey guys,
I'm making a plugin that runs on a countdown and I've got it mostly working, but I keep having an issue.
The countdown starts correctly, displays the first number then stops. Here's what it looks like: http://gyazo.com/0796dab8b3fc2c9e5b40c4359dfaa979
I can get it to count down from 30 correctly but I want it to only display the numbers 30, 20, 10, 5, 4, 3, 2, and 1.
Here's my code.

Main Class:

Code:

package me.candlecountdown;

import org.bukkit.event.Listener;
import org.bukkit.plugin.java.JavaPlugin;

public class Candlecountdown extends JavaPlugin implements Listener {
    private static Candlecountdown plugin;
    @Override
    public void onEnable() {
        new Countdown(this);
        plugin = this;
     
    }
    public static Candlecountdown getPlugin() {

        return plugin;
        }
    @Override
    public void onDisable() {
    }
}

Countdown.java:

Code:

package me.candlecountdown;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;

public class Countdown implements Listener, Runnable {
    public int number = 30;

    public Countdown(Candlecountdown plugin) {
        plugin.getPluginManager().registerEvents(this, plugin);

    }

    @SuppressWarnings("deprecation")
    @EventHandler
    public void onJoin(PlayerJoinEvent e) {
        if (!(Bukkit.getServer().getOnlinePlayers().size() <= 1)) {
            Bukkit.broadcastMessage(ChatColor.RED + "Preparing to start game...");
            Bukkit.getServer().AsyncRepeatingTask(Candlecountdown.getPlugin(), new Runnable() {
                public void run() {
                    if (number % 10 == 0 || number <= 5 && number != 0) {
                        Bukkit.broadcastMessage("" + 
        } else {
            Bukkit.broadcastMessage(
                    ChatColor.RED + "Waiting on" + " " + ChatColor.YELLOW + "1" + " " + ChatColor.RED + "more player");
        }
    }

    @Override
    public void run() {
        // TODO Auto-generated method stub

    }
}

EDIT: Just to be clear I know how to make a countdown. Please don't tell me to change any code that doesn't pertain to my issue, as there are many ways to make a countdown and this one is what I chose.

What is your code currently broadcasting? Also, to cancel the task, you can replace the scheduler with a BukkitRunnable instance where you call the run() method in, in there is a method "cancel" that cancels the timer.

I have to admit i LOVE your name Haha! Ehm back on topic.
Where exacly is the broadcasting taking place? And as it was recomended above use a BukkitRunnable that is easy to schedule, run timmer, and cancel.

It currently broadcasts "Preparing to start game..." "30" then it stops

@mine-care
Thanks <3 and all the broadcasting is in here:

Code:

   if (!(Bukkit.getServer().getOnlinePlayers().size() <= 1)) {
            Bukkit.broadcastMessage(ChatColor.RED + "Preparing to start game...");
            Bukkit.getServer().getScheduler().scheduleAsyncRepeatingTask(Candlecountdown.getPlugin(), new Runnable() {
                public void run() {
                    if (number % 10 == 0 || number <= 5 && number != 0) {
                        Bukkit.broadcastMessage("" + number);
                        number--;
                    } else if (number == 0) {
                        Bukkit.broadcastMessage(ChatColor.RED + "Starting game");
                        number--;
                    }

If you had read the thread you could've known that I can create a simple countdown, my trouble comes when I try to make it only display certain numbers.

 

@Candle is taken :I
I found your issue. You're only decreasing the number when the number is dividable by 10 or smaller than 5, remove both of the number-- and put one at the beginning of the method

ahh I see, thanks!
