Unable to make connection with database using selenium

Question

While am trying to connect to the mySQL database,getting the exception and am able to load the driver.This is the piece of code i wrote:

Connection con = null;

Class.forName("com.mysql.jdbc.Driver");

System.out.println("Driver Loaded");

try{ con =DriverManager.getConnection("jdbc:mysql://localhost:3306/DBName","username","password");

System.out.println("Connected to mySQL DB");

}catch(SQLException e){

e.printStackTrace();

And i am getting the following exception-------------

com.mysql.jdbc.CommunicationsException: Communications link failure due to underlying exception: 

** BEGIN NESTED EXCEPTION **
