of the show is to demonstrate the preparation of a specific meal.

Some of these patterns, such as the General Responsibility
Assignment Software Patterns (GRASP),1 are so fundamental that many
other patterns make use of them. Basic design patterns organize and
control communication or creation, or they establish visibilities
among objects. Basically, in an object-oriented system, JadeLiquid

with each other through messages. Therefore all these messages
