Solved Cooldown

Hello, how do I make a cooldown to this egg system so that if the player right clicks an egg it will start a cooldown at 20 sec and after that 20 sec it should do something. This is my code:

Code:

 @EventHandler
                                                        public void onPlayerInteract8(PlayerInteractEvent e){                                                    
                                                         Player p = e.getPlayer();
                                                           if(e.getAction() == Action.RIGHT_CLICK_BLOCK){
                                                                Block b = e.getClickedBlock();
                                                              if(b.getType().equals(Material.DRAGON_EGG)){
                                                                    e.setCancelled(true);
                                                                    if(getConfig().getConfigurationSection("loc") == null) {
                                                                       
                                                                         //SET IT:
                                                                        getConfig().set("loc.world", b.getLocation().getWorld().getName());
                                                                        getConfig().set("loc.x", b.getLocation().getX());
                                                                        getConfig().set("loc.y", b.getLocation().getY());
                                                                        getConfig().set("loc.z", b.getLocation().getZ());
                                                                        saveConfig();
                                                                        p.sendMessage(ChatColor.GREEN + "Location set, sir!");
                                                                        return;

I am using this API, so there should be an easier way trough this API:

Code:

package First;

import org.bukkit.entity.Player;

import com.google.common.collect.HashBasedTable;
import com.google.common.collect.Table;

public class Cooldowns {
    private static Table<String, String, Long> cooldowns = HashBasedTable.create();
   
    /**
     * Retrieve the number of milliseconds left until a given cooldown expires.
     * <p>
     * Check for a negative value to determine if a given cooldown has expired. <br>
     * Cooldowns that have never been defined will return {@link Long#MIN_VALUE}.
     * @param player - the player.
     * @param key - cooldown to locate.
     * @return Number of milliseconds until the cooldown expires.
     */
    public static long getCooldown(Player player, String key) {
        return calculateRemainder(cooldowns.get(player.getName(), key));
    }
   
    /**
     * Update a cooldown for the specified player.
     * @param player - the player.
     * @param key - cooldown to update.
     * @param delay - number of milliseconds until the cooldown will expire again.
     * @return The previous number of milliseconds until expiration.
     */
    public static long setCooldown(Player player, String key, long delay) {
        return calculateRemainder(
                cooldowns.put(player.getName(), key, System.currentTimeMillis() + delay));
    }
   
    /**
     * Determine if a given cooldown has expired. If it has, refresh the cooldown. If not, do nothing.
     * @param player - the player.
     * @param key - cooldown to update.
     * @param delay - number of milliseconds until the cooldown will expire again.
     * @return TRUE if the cooldown was expired/unset and has now been reset, FALSE otherwise.
     */
    public static boolean tryCooldown(Player player, String key, long delay) {
        if (getCooldown(player, key) <= 0) {
            setCooldown(player, key, delay);
            return true;
        }
        return false;
    }
   
    /**
     * Remove any cooldowns associated with the given player.
     * @param player - the player we will reset.
     */
    public static void removeCooldowns(Player player) {
        cooldowns.row(player.getName()).clear();
    }
   
    private static long calculateRemainder(Long expireTime) {
        return expireTime != null ? expireTime - System.currentTimeMillis() : Long.MIN_VALUE;
    }
}

 

Code:

        Bukkit.getScheduler().scheduleSyncDelayedTask(Instance from the MainClass, new Runnable() {
           
            @Override
            public void run() {
                 //Here you type in, what you wanna do after 20 Seconds
            }
        }, 20*20L);
