  • Not a very good exampleSteve March 21, 2012 at 1:22 AM

    Embedding the definition of "check.message()" within the creation of the object was a poor way to illustrate how to create an interface. This is a sloppy way of programming that results in ugly, unreadable code and is a practice that should be discouraged (at least for professional applications).
