    Question calling a constructor

    I have created my class and one constructor in the class and I now want to call my class in the main method.
    How do I call the constructor then. My code looks like this

    import java.sql.*;
       import java.io.*;
       import javax.swing.JOptionPane;
        public class MyConnection
       {
          Connection conn;
           public  MyConnection()
          {
          //load the driver
     
             try
     
             {
                Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
                System.out.println ("Driver successfully loaded");
             }    
                 catch (ClassNotFoundException c)
                {
                   System.out.println ("Unable to load database driver");
                }
          //connect to the database
             try
             {
     
                BufferedReader inKb = new BufferedReader (new InputStreamReader(System.in));
             //String filename = inKb.readLine();
                String filename = "c:/mydatabase.mdb";
                String database = "jdbc:odbc:Driver={Microsoft Access Driver(*.mdb)};DBQ=";
                database += filename.trim () + ";DriverID=22;READONLY=true}";
                conn = DriverManager.getConnection (database, "", "");
                System.out.println ("Connection to Disease database successfully established");
             }
                 catch (Exception e)
                {
                   System.out.println ("Unable to connect to the database");
                }
          } //end connect
       }
