Self-Cancelling Task?

I am working on a plugin which has a clearchat command. This command will send each player who doesn't have a certain permission a message (which happens to be blank). I know there is a way to make a task that will cancel itself after a certain number of times of it being run, but I don't remember how to do so. I am currently using the very innefficent method of repeating p.sendMessage(""); over and over. Here is a snippet of my code. I cut out all of the other parts with p.sendMessage(""); just know that they are there.

Code:

for (Player p : Bukkit.getServer().getOnlinePlayers()) {
                if (!(p.hasPermission("chatmanager.clearchat.exempt"))) {
                    p.sendMessage("");
                }
            }

The code itself works fine, I just want to know how to do it more efficiently.

 

@henderry2019 have a look here. There are some examples that do exactly what you want.

I looked at http://wiki.bukkit.org/Scheduler_Programming#Self-Canceling_Example, but it won't let me put my public void run() inside of my command.

 

@henderry2019 make a new method for it.

 

@henderry2019

The way you're doing it is fine, if pointless.

 

Are you looking for a for(int i = 0; i <50; i++) loop?
