Topic

Take the principle of Separation of Responsibility and catalog the information on it available on the Web. Find good descriptions and good, concise, understandable examples. Tell which you consider the best to present to a class.

Defination of Separation of Responsibility

In Object-Oriented Design (OOD)

  • One class should be responsible for knowing and maintaining a set of data, even if that data is used by many other classes.
  • Different responsibilities should be divided among different objects. Ideally, each individual object has one single responsibility, which we call Single Responsibility Principle (SRP).

The Advantage of Separation of Responsibility

  • Decreases the coupling between two classes. One class do not need to know the what happened in the other class and what kind of object the pointer points to.
