Scoreboard Countdown doesn't work

Hello guys,

I just started making some plugins for Bukkit. But when I tries to make a Countdown in a Scoreboard I got a bug in my code. Here is my code will explain more down below.

Code:

public class JoinBoard implements Listener{

  
  
    public static Main plugin;
  
    public JoinBoard(Main instance){
        plugin = instance;
    }
  
    public static int count = 121;
  
    public static int timer;
  
    public static Scoreboard board = Bukkit.getScoreboardManager().getNewScoreboard();
    public static Objective ob = board.registerNewObjective("PlayerScoreboard", "dummy");
  
  
    public static void updateScoreboard(final Player p){
      
  
    ob.setDisplaySlot(DisplaySlot.SIDEBAR);
    ob.setDisplayName(ChatColor.GREEN + "[" + ChatColor.RED + "Pizza Place" + ChatColor.GREEN + "]");
  
  
  
    timer = Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask(plugin, new Runnable() {
  
    @Override
    public void run() {
    count --;
  
    for(String entry : board.getEntries()){
        board.resetScores(entry);
    }
  
    Score score4 = ob.getScore(" ");
    score4.setScore(4);
  
    Score score = ob.getScore(ChatColor.GRAY + "Players: " + Bukkit.getServer().getOnlinePlayers().size() + "/6");
    score.setScore(3);
  
    Score score1 = ob.getScore("  ");
    score1.setScore(2);
  
    Score score2 = ob.getScore(ChatColor.GRAY + "Time: " + count + "s");
    score2.setScore(1);
  
  
    if(count == 30){
        Bukkit.broadcastMessage(count+ " seconds remaining!");
    }else if(count <= 10){
        p.playSound(p.getLocation(), Sound.SUCCESSFUL_HIT, 10, 1);
        Bukkit.broadcastMessage(count+ " seconds remaining!");
    }else if(count == 0) {
        p.playSound(p.getLocation(), Sound.SUCCESSFUL_HIT, 10, 1);
        Bukkit.getServer().getScheduler().cancelTask(timer);
  
    if(Bukkit.getServer().getOnlinePlayers().size() == 6){
        Bukkit.broadcastMessage("Fck Yeah!");
    }else{
      
      
    }
    }
    }
    }, 0L, 20L);
          
    }
  
  
    @EventHandler
    public void onJoin(PlayerJoinEvent e){
    Player p = e.getPlayer();
      
    if(Bukkit.getServer().getScheduler().isCurrentlyRunning(timer)){
      
    }else{
        p.setScoreboard(board);
        updateScoreboard(p);
    }
    }

}

So the countdown works but when I relog on my server the countdown is running twice. I tried everything but I couldn't fix it. Hopefully you guys can help my. And yes I know my code is shit but i'm just trying.

 

@Code4Life

First, make "plugin" private and remove the static.

This is static abuse. Please stop making everything static and create getters and setters.

MAIN PROBLEM: you do not fully understand Static/ are misusing static. Remove the static modifiers and it will fix your problem.

 

@Zombie_Striker Thanks for your reply but it still doesn't work I replaced everything to private but when I relog it still runs twice.
