Solved Help with calling an int function in the main plugin class

Hello, I can't seem to figure out how to call a function(in another class) that returns an integer(how many coins the player has). I have tried to search for multiple answers but to no avail, I haven't found any.

 

@timtower And how would that look?

 

Here you go:

Code:

public int getCoins(Player player) {
        String uuid = player.getUniqueId().toString();
        File userdata = new File(this.getServer().getPluginManager().getPlugin("Marketplace").getDataFolder(), File.separator + "PlayerDatabase");
        File f = new File(userdata, File.separator + uuid + ".yml");
        FileConfiguration playerData = YamlConfiguration.loadConfiguration(f);
        if(f.exists()) {
            try {
                playerData.load(f);
                int coins = (int)playerData.get("coins");
                return coins;
            }
            catch(Exception e) {
                Bukkit.broadcastMessage("Error getCoins: "+e.toString());
            }
        }
        setCoins(player,0);
        return 0;
}

 

Yes:

Code:

Main main = new Main();
int coins = main.getCoins(player);

And that returns a NullPointerException

 

@timtower Okay, I figured out how to fix it. Thank you.
