Help with Bukkit Runnables and run task timer

Code:

public class WandEventsclass implements Listener{
  

    @SuppressWarnings("deprecation")
    @EventHandler
        public void onUse(PlayerInteractEvent e) {
        
        Player p = e.getPlayer();
         ItemStack item = p.getItemInHand();
         ItemMeta meta = item.getItemMeta();
          
            if (p instanceof Player) {
                if(p.getItemInHand().getType() == Material.STICK) {
                    if(e.getAction() == Action.LEFT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK) {
                        if(meta.getDisplayName().equalsIgnoreCase("Staff")){
                            p.sendMessage("Pew!");
                          
                        Snowball ball = p.getWorld().spawn(p.getEyeLocation(), Snowball.class);
                      
                        ball.setShooter(p);
                        ball.setVelocity(p.getLocation().getDirection().multiply(1.5));
                          
                                BukkitTask task = new BukkitRunnable() {
                                    public void run() {
                                        Firework f = p.getWorld().spawn(p.getEyeLocation(), Firework.class);

                                        ball.addPassenger(f);
                                        f.detonate();   
                                    }
                                  
                                }.runTaskTimer(, 0L, 20L );
                          }
                    }                          
               }
          }
    }
}

Sorry about the codes alignment lol, not sure what happened.

@timtower cheers for the reply, I need the firework to repeat explode as it follows the snow ball after it was been cast so some sort of loop every half second

 

just the single explosion on launch of snowball, the explosion effect, it does not trail a,long with the snowball. cheers again

 

the snowball fly's but the explosion effect is not carried as the ball gets thrown, I want some sort of loop that I could set that makes the effect happen every couple ticks at the ball goes through the air, that's basically what I am trying to do.

 

Code:

if (p instanceof Player) {
                if(p.getItemInHand().getType() == Material.STICK) {
                    if(e.getAction() == Action.LEFT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK) {
                        if(meta.hasDisplayName()){
                            p.sendMessage("Pew!");
                          
                        Snowball ball = p.getWorld().spawn(p.getEyeLocation(), Snowball.class);
                      
                        ball.setShooter(p);
                        ball.setVelocity(p.getLocation().getDirection().multiply(1.5));
                          
                                BukkitTask task = new BukkitRunnable() {
                                    public void run() {
                                        Firework f = p.getWorld().spawn(p.getEyeLocation(), Firework.class);

                                        ball.addPassenger(f);
                                        f.detonate();   
                                    }
                                  
                                }.runTaskTimer(, 0L, 20L ); --------------------- This is the part that is coming up with and error
                          }
                    }                          
               }

 

}.runTaskTimer(, 0L, 20L ); its telling me to remove the first comma in the parenthesises

The method runTaskTimer(Plugin, long, long) in the type BukkitRunnable is not applicable for the arguments (long, long) - error, when the comma is removed...

in what respect? sorry I think this is where I am forgetting / stuck here, the plugin like the Main or?? Sorry for noob in this area

 

I tried referencing it but it didnt work

 

if(meta.hasDisplayName()){ <---(IN PINK) this part here I want to reference a specific name not just nay display name
p.sendMessage("Pew!");

Snowball ball = p.getWorld().spawn(p.getEyeLocation(), Snowball.class);

ball.setShooter(p);
ball.setVelocity(p.getLocation().getDirection().multiply(1.5));

BukkitTask task = new BukkitRunnable() {
public void run() {
Firework f = p.getWorld().spawn(p.getEyeLocation(), Firework.class);

ball.addPassenger(f);
f.detonate();
}

}.runTaskTimer(Main, 0L, 20L );

DO you have an exg fr me of that? I have been looking all over

private Main main;
public MinorWandEventsclass(Main main) {
this. main = main;
main.getServer().getPluginManager().registerEvents(this, main);
}

and in main class:
new MinorWandEventsclass(this);
