Without trying to be comprehensive or tedious, we want to end this chapter with some hints that may make your classes more acceptable in well-mannered OOP circles.
After all, the users of your class are more interested in the public interface than inthe details of the private implementation. And they are more interested in methods than in data.
However, there is no universal agreement on what is the best style. The Sun coding style guide for the Java programming language recommends listing fields first andthen methods. Whatever style you use, the most important thing is to be consistent.
This class really implements two separate concepts: a deck of cards, with its shuffle and draw methods, and a card, with the methods to inspect the value and suit of acard. It makes sense to introduce a Card class that represents an individual card.Now you have two classes, each with its own responsibilities:
A good convention is that a class name should be a noun (Order) or a noun preceded by an adjective ( RushOrder) or a gerund (an “-ing” word, like Billing Address). As for methods, follow the standard convention that accessor methods begin with a lower caseget (getSalary), and that mutator methods use a lowercase set (setSalary).
