Adding countdown

I want to add a countdown from 15 sec and when it hits 0 it runs a piece of code heres my code so far.

Code:java

@EventHandler
    public void onPlayerInteract11(PlayerInteractEvent event) {
 
        Player player = event.getPlayer();
        if (event.getAction().equals(Action.RIGHT_CLICK_BLOCK)) {
            if (event.getClickedBlock().getType() == Material.GOLD_BLOCK) {
                event.setCancelled(true);
              Bukkit.broadcastMessage(player.getName()+ " Has just armed the Red teams bomb!");
              event.getClickedBlock().setType(Material.REDSTONE_BLOCK);
 
 
 
 
 
 
 
 
 
                }}}

 

Code:java

new BukkitRunnable(){
  @Override
  public void run(){
    //Do code
  }
}.runTaskLater(plugin, 300L); //20 ticks/second * 15 seconds = 300 ticks

 

thatdubstepgamer Use chasechocolate codes, and run it every second. Then, you can use a switch() statement, or do a in if, and check if the counter int variable is at a certain number, if so, do code.
