Wait amount of Ticks, then doing Action

So basically I want an action to happen a certain amount of ticks after an event.
Here is my code.

Code:java

package me.Ian0526;
 
import java.util.logging.Logger;
 
import org.bukkit.ChatColor;
import org.bukkit.Effect;
import org.bukkit.Location;
import org.bukkit.Sound;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.event.player.PlayerLoginEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.Plugin;
import org.bukkit.plugin.RegisteredServiceProvider;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.potion.PotionEffect;
import org.bukkit.potion.PotionEffectType;
 
public class Core extends JavaPlugin implements Listener {
  public static Plugin plugin;
  public final Logger logger = Logger.getLogger("Minecraft");
 
  public void onEnable() {
      getServer().getPluginManager().registerEvents(this, this);
  }
  public void onDisable() {
    this.logger.info("[ZetaCraftFJDonor] Plugin Disabled");
    logger.info(String.format("[%s] Disabled Version %s", getDescription().getName(), getDescription().getVersion()));
  }
  @EventHandler
  public void PlayerJoin(PlayerJoinEvent event){
      Player player = event.getPlayer();
      Location loc = player.getLocation();
          if(player.hasPlayedBefore()){
          }else{
                        ##Waitevent.300ticksblahblah
              player.playEffect(loc, Effect.ENDER_SIGNAL, 2003);
              player.addPotionEffect(new PotionEffect(PotionEffectType.BLINDNESS, 50, 1));
              player.addPotionEffect(new PotionEffect(PotionEffectType.SPEED, 4000, 3));
              player.sendMessage("§aWelcome! Take some starter items, money and §2SPEED§a! To get started!");
          }
  }
}

 

Don't you mean "WAT" amount of ticks. Anyways, getting to your problem.. Are you wanting to know how to do it, or Is there a problem because "##Waitevent.300ticksblahblah" Just confuses me.

 

I want to wait an amount of ticks before doing an action after an event.

The question I am asking you is: Are you inquiring how to do it? Or is there a problem with your code.
EDIT: If you're inquiring about it I recommend you watch this video:

 

You are looking for SchedualSyncDelayedTask (PS its a Runnable())
