Hi all, in singleton design pattern. We normally have a method call getInstance() which takes in no argument. I'm wondering is it ok to pass in a parameter, for eg. java.sql.Connection to retrieve record from the database?

You can do anything you want, but the normal purpose of the getInstance() method in a singleton class is to return an instance of the class. You then use that instance to call other methods of the class to do whatever processing you want.
