Question

What two questions should you ask to determine a class's responsibilities?

Short answer

Answer: To determine a class's responsibilities, we need to answer two fundamental questions: 1. What does this class represent? Identify the real-world entity or concept the class models, its attributes (properties), and behaviors (methods). 2. What are the relationships between this class and other classes? Analyze the associations, aggregations, and compositions that the class has with other classes in the application to understand its responsibilities within the overall structure of the object-oriented design.

Step-by-step solution

Question 1: What does this class represent?

Consider the real-world entity or concept that the class models. Identify its attributes (properties) and behaviors (methods). This helps in understanding the purpose of the class and its responsibilities in the OOP context.

Question 2: What are the relationships between this class and other classes?

Analyze the associations, aggregations, and compositions that this class may have with other classes in the application. Understanding how the class interacts with other classes will help in determining its responsibilities in the overall structure of the object-oriented design.
