9Constants are permitted to depend on other constants within the same program as long as the dependencies

10are not of a circular nature. The compiler automatically arranges to evaluate the constant declarations in the

11appropriate order. [Example: In the following code

12class A

13{

15public const int Y = 10;

16}

17class B

18{

19public const int Z = A.Y + 1;

20}

21the compiler first evaluates A.Y, then evaluates B.Z, and finally evaluates A.X, producing the values 10, 11,

22and 12. end example] Constant declarations can depend on constants from other programs, but such

23dependencies are only possible in one direction. [Example: Referring to the example above, if A and B were

24declared in separate programs, it would be possible for A.X to depend on B.Z, but B.Z could then not

25simultaneously depend on A.Y. end example]

2617.4 Fields

27A field is a member that represents a variable associated with an object or class. A field-declaration

28introduces one or more fields of a given type.
