Query about Connection interface

[sparsh khandelwal]

hello everyone,
i try the following command

import java.sql.*;
class MySql{
public static void main(String args[]){
Connection con=null;
String user="root";
String pass="root";
String db="don";
String driver="com.mysql.jdbc.Driver";
String url="jdbc:mysql://localhost:3306/";
try
{
Class.forName(driver);
con=DriverManager.getConnection(url+db,user,pass);
System.out.println(con);
System.out.println("Connected");
con.close();
System.out.println("Disconnected");
}
catch(Exception e)
{
e.printStackTrace();
}
}
}

and found the output as given in snapshot,
i am new to jdbc, i am not able to understand the output of this command here

System.out.println(con);

You first print out your connection object, which just prints the reference used by the JVM to keep track of the object. Then you print the words Connected and Disconnected, so that's what you see in the console. What are you hoping to see?
