Example text

Hence, data integrity is preserved. Furthermore, by making methods public, access and modification to data is controlled via the methods of the class. Hence, no direct external access by other objects ensures that data behavior is also preserved. As a rule of thumb, good class design declares data fields as private and methods as public. It is also suggested that methods to retrieve data members (called getters) and methods to change data members (called setters) be public and protected, respectively.

Together, these classes define a complete program in C#. GetFirstName() ); } } } To produce an executable program in C#, one of the classes, in this case TestId, must define a static method called Main from where the program starts to run and to where we focus our attention. On lines 6 and 7, two constant values, NumberOfEntries and NameSeparator, are initialized, respectively, to the integer literal 5 and the character literal ‘/’. An instance of the class Id is created on line 9 and assigned to an object reference called id where its fields, firstName and lastName, are assigned to literal strings "" and "".

Because each class encapsulates both data and behavior, it is relatively easy and economical to define new classes in terms of others. Issues related to inheritance, such as constructor/destructor chaining and protected data members, are also discussed. 1 Fields and Methods The fields and methods of a C# class may be associated with either the class itself or with particular objects of the class. In the former case, these members are called static fields and static methods and are not part of any object instantiated from the class.
