Listing3-47 uses @Stub toannotatethe Deck class,the cardsRemaining field,
andthe ncards parameteraswellasannotatingtheconstructorandthetwomethods.
The first three application elements are inappropriate to annotate because they are not
stubs.
You can fix this problem by prefixing the Stub annotation type declaration with
@Target({ElementType.METHOD, ElementType.CONSTRUCTOR}) so
that Stub onlyappliestomethodsandconstructors.Afterdoingthis,the javac com-
