What is the recommended way to make a timer in Bukkit?

I have been looking up how to create a timer in Bukkit, but I see that some people use BukkitScheduler, BukkitTask, and BukkitRunnable. What am I supposed to use?

 

Read up on it here.

Personally, I like BukkitRunnable. Nice and easy and clean.

Code:

new BukkitRunnable() {
  int counter = 0;

  @Override
  public void run() {
    Bukkit.broadcastMessage("Yay spam!");
    counter++; if (counter == 4) this.cancel();
  }
}.runTaskTimer(this, 0L, 20L);

 

A easy and simple way to have repeating tasks is by setting up an abstract class like this:

Code:

import org.bukkit.Bukkit;
import org.bukkit.plugin.java.JavaPlugin;

public abstract class RepeatingTask implements Runnable {

    private int taskId;

    public RepeatingTask(JavaPlugin plugin, int arg1, int arg2) {
        taskId = Bukkit.getScheduler().scheduleSyncRepeatingTask(plugin, this, arg1, arg2);
    }
    public void cancel() {
        Bukkit.getScheduler().cancelTask(taskId);
    }
}

And then calling it in any other class you want to create a repeating timer in using this:

Code:

new RepeatingTask (plugin, 0, 20) { //first int for initial delay in ticks and second int for time between intervals in ticks
    @Override
    public void run() {
        //code to run every 20 ticks (1 second)
        cancel(); // you can use this internally or externally if you create an instance to cancel the task when your finished to reduce lag
    }
};
