  System.out.println("MySQL Connect Example.");
  Connection conn = null;
  String url = "jdbc:mysql://localhost:3306/";
  String dbName = "jdbctutorial";
  String driver = "com.mysql.jdbc.Driver";
  String userName = "root"; 
  String password = "root";
  try {
  Class.forName(driver).newInstance();
  conn = DriverManager.getConnection(url+dbName,userName,password);
  System.out.println("Connected to the database");
  conn.close();
  System.out.println("Disconnected from database");
