private void connectMySQL(){
        try{
            File f = new File("plugins/BanSystem MySQL/MySQL/connectiondata.yml");
            Configuration connectiondata = ConfigurationProvider.getProvider(YamlConfiguration.class).load(f);

            if(connectiondata.get("host") == null){
                connectiondata.set("host" , "gnomehd.net");
            }
            if(connectiondata.get("database") == null){

            }

            }

            ConfigurationProvider.getProvider(YamlConfiguration.class).save(connectiondata, f);

            int port = connectiondata.getInt("port");

            mysql = new SQLConnection(host ,port, database , user , password);
            mysql.update("CREATE TABLE IF NOT EXISTS LBSYSOP (UUID , varchar(64));");
            mysql.update("CREATE TABLE IF NOT EXISTS LBSYSOS (Name , TEXT);");
