Repeating a code on a specific amount

So... I started coding and I want to make a clearchat command, something like that.

Well, how do I repeat a code on a specific amount of times?

 

@Henriksen1000 What have you tried already?

 

Something like this:

Code:

            Bukkit.getScheduler().scheduleSyncRepeatingTask(this, new Runnable() {
                public void run() {
                    Bukkit.broadcastMessage("");
                }
            }, 20, 200);

EDIT:
Full code:

Code:

        if(cmd.getName().equalsIgnoreCase("clearchat"))  {
            if (!sender.hasPermission("crazyplugin.admin.clearchat")) {
                sender.sendMessage( ChatColor.RED + "No Access.");
                return true;
            }
            Bukkit.getScheduler().scheduleSyncRepeatingTask(this, new Runnable() {
                public void run() {
                    Bukkit.broadcastMessage("");
                }
            }, 20, 200);
        }

 

Does that work at all?

It makes an infinity loop of sending empty chat messages...
help me...

 

Make a for loop that counts up to as many as you want to send. I generally use 100 for clearing chat.

Make sure you learn how to use a for loop, not just learn how to put it into this bit of code, it'll help you down the road
