Solved Teleport all Players if the Countdown is over

Hello I want to program a plugin and in this plugin a countdown is started when two players are on the server. When the countdown is over, all players should be teleported to another world, and that doesn't work for me.
PS: Sorry for my bad english.

Code:

Code:

package de.asmax.speeduhc.lobby;import de.asmax.speeduhc.main.Main;import org.bukkit.Bukkit;import org.bukkit.Location;import org.bukkit.entity.Player;import org.bukkit.event.EventHandler;import org.bukkit.event.Listener;import org.bukkit.event.player.PlayerJoinEvent;public class LobbyCountdown implements Listener {

private int taskID;@EventHandlerpublic void onPlayerJoin(PlayerJoinEvent e) {

Player p = (e.getPlayer()); if(Bukkit.getOnlinePlayers().size() == 2) {

taskID = Bukkit.getScheduler().scheduleSyncRepeatingTask(Main.getPlugin(), new Runnable() {

int countdown = 60;@Overridepublic void run() {
switch(countdown) {
case 60: case 30: case 15: case 10: case 5: case 4: case 3: case 2:
Bukkit.broadcastMessage("§7Die Runde SpeedUHC startet in §6" + countdown + " §7sekunden" ); break; case 1:
Bukkit.broadcastMessage("§7Die Runde SpeedUHC startet in §6einer §7Sekunde"); break; case 0:
Bukkit.broadcastMessage("§6Die Runde SpeedUHC wird gestartet!"); for (Player p: Bukkit.getOnlinePlayers()) {
p.teleport(new Location(Main.getPlugin().getServer().getWorld("SpeedUHC"),-123.15,65.3,1));}
Bukkit.getScheduler().cancelTask(taskID); return; default:
break;}
countdown--;}
}, 0, 20);} else {
Bukkit.broadcastMessage("§cEs sind noch nicht genügent Spieler in der Runde, es fehlt noch ein weiterer Spieler!");}

}
}

 

@AsMax Which part of it is not working? Did you register the listener?
