        next = new Button("Next");
        p1.add(new Label("book-id"));
        p1.add(t1);
        p1.add(new Label("book-title"));
        p1.add(t2);
        p1.add(next);
        next.addActionListener(this);
        pack();
        setVisible(true);

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == next) {
            try {

            String database = "jdbc:odbc:Driver={Microsoft Access Driver (*.accdb)};DBQ=MyDatabase.accdb;DriverID=01";
            Connection con = DriverManager.getConnection(database, "", "");
            Statement state = con.createStatement();
            System.out.println(rs.getString(1));
            System.out.println(rs.getString(2));
            rs.next();

Verify you have de correct access drivers in the machine (Access 2013 redistributables). It could be x86 or x64. Jre/Jdk should be in concordance: x86 or x64
