public class PlayerInteract implements Listener{
@EventHandler
    public void onPlayerInteract(PlayerInteractEvent event) {
Player p = event.getPlayer();
        ItemStack item = event.getItem();
        if (item != null && item.getType() == Material.BLAZE_ROD) {
       event.getAction().equals(Action.RIGHT_CLICK_AIR);
            item.getType().equals(Material.BLAZE_ROD);
           p.sendMessage(ChatColor.YELLOW+"You fired a fireball, need help? type: /bhelp for help!");
           p.launchProjectile(SmallFireball.class);
           if (p.getGameMode().equals(GameMode.SURVIVAL)) {
           if (item.getAmount() == 1) {
                        event.getPlayer().getInventory().remove(item);
           } else
                         item.setAmount(item.getAmount() - 1);
                 }
        }
}
}
