jangan lupa ADD LIBRARY di dibagian libraries project, pilih MySQL JDBC Driver

package Application;
import java.sql.*;

public class Koneksi {
public Connection dbKoneksi;
public Statement statement;
public PreparedStatement prepareStatement;
public CallableStatement callableStatement;

public Koneksi() {
this.dbKoneksi = null;
}

public void bukaKoneksi() {
    try {
            /*   utk ms-access
             Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            dbKoneksi = DriverManager.getConnection("jdbc:odbc:kursus");
             */
            Class.forName("com.mysql.jdbc.Driver");
            dbKoneksi = DriverManager.getConnection
                    ("jdbc:mysql://localhost:3306/bengkel","root", "likmi");
         }
         catch(Exception e){
             e.printStackTrace();
         }
}
public void tutupKoneksi(){
       try {
            if (statement != null)
                statement.close();
            if (prepareStatement != null)
                prepareStatement.close();
            if (dbKoneksi != null)
                dbKoneksi.close();
       } catch (Exception e) {
         throw new RuntimeException(e.getMessage());
      }
}
}
