102: What is the meaning of a subsystem in real world applications?

Answer:

In real world applications, a subsystem could comprise of a large number of classes. Clients of a subsystem may need to interact with a number of subsystems classes for their needs. This kind of direct interaction of clients with subsystems classes leads to a high degree of coupling between the client’s objects and the system. Whenever a subsystem class undergoes a change, such as change in its interface, all of its dependent client classes may get affected.

Answer:

This client contains an object reference of Memento type; it is passed as a Memento instance by the client DCClient.

 

176: Which is the third step converting an algorithm into individual Methods?
