Why would you ever make a private constructor that just sounds stupid. Also I use abstract when I want to extend something. like lets say I have a customer generator. Then I want to have a uniform customer generator, and a bell curve customer generator. If I made the customer generator an interface there would be a lot of dupliction of code whereas if I make customer generator class abstract then uniform would have to just have decide when to create a customer and not have to worry about actually generating a customer.
