In the previous example of electric lights, a state mode program was completed. First, the Light class is defined, which is also called Context here. Then in Light's constructor, to create instance objects for each state class, Context will hold references to these state objects in order to delegate the request to the state objects.

Another expression of the minimum knowledge principle is to communicate only with direct friends. As long as there is a coupling relationship between classes, it is called a friend relationship. Coupling is divided into dependency, association, aggregation, combination, etc. We call classes that appear as member variables, method parameters, and method return values direct friends. Local variables and temporary variables are not direct friends. We require unfamiliar classes not to appear in the class as local variables.
