    System.out.println("Getting All Rows from a table!\n");

    BasicDataSource bds = new BasicDataSource();

    bds.setDriverClassName("com.mysql.jdbc.Driver");

    bds.setUrl("jdbc:mysql://localhost:3306/mydb");

    bds.setUsername("root");

    bds.setPassword("");

    try {

      Connection con = bds.getConnection();

      try {

        Statement st = con.createStatement();

        ResultSet res = st.executeQuery("SELECT * FROM  users");

        System.out.println("ID: " + "\t\t" + "NAME: ");

        while (res.next()) {

          int i = res.getInt("id");

          String s = res.getString("name");

          System.out.println(i + "\t\t" + s);

        }

        con.close();

      } catch (SQLException s) {

        System.out.println("SQL code does not execute.");
