Hello dear friends:
I wrote this code, I was wondering if you want to make a bet if I should apply to acknowledge how do I connect?
The code:

Class.forName("com.mysql.jdbc.Driver").newInstance  ();
    String url="jdbc:mysql://localhost:3306/dbcn?user=root&password=";
    Connection con= DriverManager.getConnection(url);

For example in php:

if ($resault)
echo "successful";
