9.4 Getting Connections

The driver manager DriverManager offers the following methods for connecting to databases through java.sql.Connection objects.

static Connection getConnection(String url)
static Connection getConnection(String url, String username, String password)
The database is identified by a URL of the following form.

jdbc:subprotocol:database-name

The subprotocol is provided by the database developer.

import java.sql.*;

public class Connect {
   public static void main(String args[]) {
     try {
       Class.forName("com.mysql.jdbc.Driver");
       String url = "jdbc:mysql://localhost/test";
       Connection con =
            DriverManager.getConnection(url);

       if(!con.isClosed()){
         System.out.println("Hurray!");
         con.close();
       }
     } catch(Exception e) { System.err.println("error"); }
} }
