Java Reference
In-Depth Information
Notice how the
final
constants are used in
main( )
. Since they are members of the
Er-
rorMsg
class, they must be accessed via an object of that class. Of course, they can also be
inherited by subclasses and accessed directly inside those subclasses.
As a point of style, many Java programmers use uppercase identifiers for
final
constants,
as does the preceding example. But this is not a hard and fast rule.
