Solved MySQL not working properly!

Hello,
I am currently trying to store player names in a mysql database but it doesn't want to set them to the database! I am currently using huskehhh mysql api.
Here is what i have reached so far (server connects successfully to the database without any problems and there are no existing errors in the console):

Code:

    public void setupDB(String address, String port, String database, String username, String password)
            throws ClassNotFoundException, SQLException {
        this.db = new MySQL(address, port, database, username, password);
        this.db.openConnection();
        Statement statement = this.db.getConnection().createStatement();
        statement.executeUpdate("CREATE TABLE IF NOT EXISTS Whitelisted(Name varchar(32));");
        statement.close();
    }

    public void closeDatabase() throws SQLException {
        if (this.db != null && !this.db.checkConnection()) {
            this.db.closeConnection();
        }
    }

    public boolean isWhitelisted(Player p) throws SQLException, ClassNotFoundException {
        if (!this.db.checkConnection())
            this.db.openConnection();
        Statement statement = this.db.getConnection().createStatement();
        ResultSet rs = statement.executeQuery("SELECT Name FROM Whitelisted WHERE Name='" + p.getName() + "'");
        if (!rs.next()) {
            //System.out.println(ChatColor.RED + "NOT Whitelisted!");
            statement.close();
            rs.close();
            return false;
        } else {
            //System.out.println(ChatColor.RED + "IS Whitelisted!");
            statement.close();
            rs.close();
            return true;
        }
    }

    public void setWhitelisted(Player p) throws SQLException, ClassNotFoundException {
        if (!this.db.checkConnection())
            this.db.openConnection();
        Statement statement = this.db.getConnection().createStatement();
        if (!isWhitelisted(p)) {
            statement.executeUpdate("INSERT INTO Whitelisted(Name) VALUES ('" + p.getName() + "');");
            db.getConnection().commit();
            statement.close();
            //System.out.println(ChatColor.RED + "NOT Whitelisted!");
        } else {
            statement.close();
            //System.out.println(ChatColor.RED + "ALREADY Whitelisted!");
        }
    }
