Hello there is no errors here but it won't work, a man tell me that I must add a delay but i don't know how, can you please help me?

// Message on server start (french)
public class UltraHardOpium extends JavaPlugin implements Listener {
private Logger logger = Logger.getLogger("Minecraft");
public void onEnable() {
getServer().getPluginManager().registerEvents(this, this);
logger.info("[UltraHard] Plugin operationnel");}
 
// Add effects to the player after he die and boost his life to the maximum
@EventHandler
public void onPlayerRespawn(final PlayerRespawnEvent r){
final Player player = r.getPlayer();
player.addPotionEffect(new PotionEffect(PotionEffectType.HEALTH_BOOST, Integer.MAX_VALUE, 9));
player.addPotionEffect(new PotionEffect(PotionEffectType.DAMAGE_RESISTANCE, Integer.MAX_VALUE, 2));
player.setHealth(player.getMaxHealth());
player.sendMessage("[Respawn] Vous gagnez 30 coeurs et de la resistance, bon jeu!");}
 
// Checking if this is the first join of a player and add him effects and boost his life to the maximum
@EventHandler
public void firstJoinDetection(PlayerJoinEvent fj)
{
Player player = fj.getPlayer();
boolean existingPlayer = player.hasPlayedBefore();
if (!existingPlayer) {
player.addPotionEffect(new PotionEffect(PotionEffectType.HEALTH_BOOST, Integer.MAX_VALUE, 9));
player.addPotionEffect(new PotionEffect(PotionEffectType.DAMAGE_RESISTANCE, Integer.MAX_VALUE, 2));
player.setHealth(player.getMaxHealth());

I had tried with this but there is errors:

Code:java

// Add effects to the player after he die and boost his life to the maximum
    @EventHandler
    public void onPlayerRespawn(final PlayerRespawnEvent r){
        Bukkit.getScheduler().scheduleSyncDelayedTask(UltraHardOpium, new Runnable() {
        @Override
        public void run() {
            final Player player = r.getPlayer();
            player.addPotionEffect(new PotionEffect(PotionEffectType.HEALTH_BOOST, Integer.MAX_VALUE, 9));
            player.addPotionEffect(new PotionEffect(PotionEffectType.DAMAGE_RESISTANCE, Integer.MAX_VALUE, 2));
            player.setHealth(player.getMaxHealth());
            player.sendMessage("[Respawn] Vous gagnez 30 coeurs et de la resistance, bon jeu!");       
    }, 200);}
 
// Checking if this is the first join of a player and add him effects and boost his life to the maximum
    @EventHandler
    public void firstJoinDetection(PlayerJoinEvent fj)
    {
      Player player = fj.getPlayer();
      boolean existingPlayer = player.hasPlayedBefore();
      if (!existingPlayer) {
          player.addPotionEffect(new PotionEffect(PotionEffectType.HEALTH_BOOST, Integer.MAX_VALUE, 9));
          player.addPotionEffect(new PotionEffect(PotionEffectType.DAMAGE_RESISTANCE, Integer.MAX_VALUE, 2));
          player.setHealth(player.getMaxHealth());
          player.sendMessage("Vous gagnez 30 coeurs et de la resistance, bon jeu!");} 
        return;}
