Solved Replace String with with Double?

I'm trying to do a motd thing here. s is a String, what i need to do is convert "[BALANCE]" in that String to the balance of a player. I had some help with this by doing .valueOf() but that didn't help much. This is what i have so far:

Code:java

                    s = s.replaceAll("[BALANCE]", String.valueOf(Main.econ.getBalance(event.getPlayer())));
 

Error is a Null Pointer right now from that statement. It uses vault.

 

megasaad44 1. replaceAll() is for regex, use replace() instead.
2. Something is null, debug the values to see which one.

 

AdamQpzm The console said the error is that line and that line only. I'm gonna try replacing ReplaceAll() with replace() (replaceception) And see what happens.

EDIT: It didn't work. same error.

megasaad44 paste whole code and say where exactly is the problem at.

Code:java

    @EventHandler
    public void onPlayerJoin(final PlayerJoinEvent event) {
        new BukkitRunnable() {
            @Override
            public void run() {
                for (String s : plugin.getConfig().getStringList("Server ingame motd")) {
                    s = ChatColor.translateAlternateColorCodes('&', s);
                    s = s.replaceAll("[PLAYER]", event.getPlayer().getName());
                    s = s.replaceAll("[DISPLAYNAME]", event.getPlayer().getDisplayName());
                    s = s.replace("[BALANCE]", String.valueOf(Main.econ.getBalance(event.getPlayer())));
                    s = s.replaceAll("[ONLINE]", String.valueOf(Main.plugin.getServer().getOnlinePlayers().length));
                    s = s.replaceAll("[MAX]", String.valueOf(Main.plugin.getServer().getMaxPlayers()));
                    event.getPlayer().sendMessage(s);
                }
            }
        }.runTaskLater(plugin, 10);
    }

megasaad44 Something on that line is null, debug the values to see which one. I feel like I've said this before.

EDIT: You know what, this is sufficient since both points are still relevant

If it returns null then my vault method is null somewhere.

Code:java

    private boolean setupEconomy() {
        if (getServer().getPluginManager().getPlugin("Vault") == null) {
            return false;
        }
        RegisteredServiceProvider<Economy> rsp = getServer().getServicesManager().getRegistration(Economy.class);
        if (rsp == null) {
            return false;
        }
        econ = rsp.getProvider();
        return econ != null;
    }

It has anti-null checks....
Do you suppose i should debug the entire motd class?

 

megasaad44 Sure, go ahead. Also, can you show me where you call setupEconomy()?

 

megasaad44 is trying to print the variables involved in the line to see if one of them is null a problem?

Fixed. If Adam hadn't asked for where setupEconomy was, i wouldn't have checked my self! I forgot to call the method onEnable(). Thanks for the help. Thread Solved
