问如何为Bukkit插件从10开始倒计时？

EN

private BukkitTask task;
private int count;

public void startTimer() {
   count = 10; // restart count down at 10 seconds
   task = Bukkit.getScheduler().runTaskTimer(MyPlugin.getInstance(), ()-> {
      // here what you want
      if(count == 0)
         task.cancel(); // cancel the task if the counter is finished
      count--; // reduce the counter
   }, 20, 20);
}

// See how many seconds have been counted
private int count;
private BukkitTask task;

public void doStuff() {
    // Reset count
    count = 0;
    task = new BukkitRunnable() {
        @Override
        public void run() {
            // If count is less than or equal to ten, increment count, otherwise set count to -1.
            count = count <= 10 ? count + 1 : -1;
            if (count >= 10 || count == -1) {
                // Cancel task if count is over 10s
                task.cancel();
                return;
            }
            Bukkit.getLogger().log(Level.INFO, "Seconds passed: " + count + "!";
        }
    }.runTaskTimer(YourPlugin.getPlugin(), 0, 20);
}
