xxmobkiller This should honestly be in Plugin Requests unless you've actually started an attempt at coding this.

 

Code:

package me.xxmobkiller.com;
 
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.event.block.SignChangeEvent;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin implements Listener {
    public void onDisable() {
        // TODO: Place any custom disable code here.
    }
 
    public void onEnable() {
        getServer().getPluginManager().registerEvents(this, this);
    }
 
      @EventHandler
      public void onSignChangeEvent1(SignChangeEvent sign) {
          String firstLine = sign.getLine(0);
          if (firstLine.equals("[online]") && firstLine.equalsIgnoreCase("Online") || firstLine.equalsIgnoreCase("online")) {
              sign.setLine(0, ChatColor.BLACK + "[Online]" );
              sign.setLine(1, ChatColor.BLACK + "[" + Bukkit.getOnlinePlayers().length + ChatColor.BLACK +"/" + Bukkit.getMaxPlayers() + ChatColor.BLACK + "]");
              sign.setLine(2, ChatColor.DARK_GREEN  + " " + "Online");
                for (Player player : Bukkit.getOnlinePlayers())
                  update(player);
              }
          }
      private void update(Player player) {
     
     }
}
