setalah kita belajar database ACCESS dan membuat ODBC. kita buat contoh input output database mahasiswa dengan membuat koneksi:
package koneksi;
import java.awt.HeadlessException;
import java.sql.*;
import javax.swing.*;
/**
*
* @author ttg
*/
public class koneksi {
void testKoneksi()
{
try
{
String dbname="jdbc:odbc:CobaDataBase"; // nama ODBC
// ingat-ingat, CobaDatabase adalah nama ODBC kita yang udah kitaatur sebelumnya
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
try (Connection con = DriverManager.getConnection(dbname,"admin","admin")) {
JOptionPane.showMessageDialog(null, "Koneksi berhasil","Insert Data",JOptionPane.INFORMATION_MESSAGE);
}
}
catch ( ClassNotFoundException | SQLException | HeadlessException e)
{
JOptionPane.showMessageDialog(null, "Eror: "+e,"Gagal",JOptionPane.WARNING_MESSAGE);
}
}
public static void main (String args[])
{
koneksi test = new koneksi();
test.testKoneksi();
System.exit(0);
}
}
kemudian untuk tampilannya menambahkan NEWFRAME
/*
