[URGANT] Hiding Players

Hello there. I am making a simple plugin for my hub that vanishes all players for all players. This is my current code:

Code:java

package me.MichaelAztan.BraveHub;
 
import java.util.logging.Logger;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
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.plugin.java.JavaPlugin;
 
public class BraveHub extends JavaPlugin implements Listener{
 
    Logger logger = Logger.getLogger("Minecraft");
    public static BraveHub plugin;
 
    public void onDisable() {
        org.bukkit.plugin.PluginDescriptionFile pdfFile = this.getDescription();
        this.logger.info("" + pdfFile.getName() + " has been disabled!");
    }
 
    public void onEnable() {
        org.bukkit.plugin.PluginDescriptionFile pdfFile = this.getDescription();
        this.logger.info("" + pdfFile.getName() + " v" + pdfFile.getVersion() + " has been enabled!");
        this.saveDefaultConfig();
 
    }
 
    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent event){
        updateHide();
    }
 
    public void updateHide(){
        Player[] players = Bukkit.getOnlinePlayers();
        for(int i = 0; i < players.length; i++){
            Player player = players[i];
            for(int e = 0; e < players.length; e++){
                player.hidePlayer(players[i]);
            }
        }
    }
 
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
        if (sender instanceof Player) {
            Player player = (Player) sender;
            if(commandLabel.equalsIgnoreCase("bravehubreload") || commandLabel.equalsIgnoreCase("bhr")){
                if(player.hasPermission("bravehub.reload")){
                    reloadConfig();
                    player.sendMessage(ChatColor.GREEN + "Config Reloaded!");
                }
                else{
                    player.sendMessage(ChatColor.DARK_RED + "You do not have access to that command.");
                }
            }
        }
        else{
            if(commandLabel.equalsIgnoreCase("bravehubreload") || commandLabel.equalsIgnoreCase("bhr")){
                reloadConfig();
                logger.info(ChatColor.GREEN + "Config Reloaded!");
            }
        }
    return false;
    }
}[/i][/i]

Here is my error:
When players join, they can see the players that were already online. But, the players that were already online cant see anyone.

I need urgent help with this.
Thanks,
Michael

 

Just put the players in a for loop.

Code:

for(Player pl : Bukkit.getOnlinePlayers(){
pl.hidePlayer(<Player>);
}
