Short Answer

Expert verified
Question 2: How can analyzing the data and information a class needs to handle help in determining its responsibilities within the system?

Step by step solution

01

Question 1: What is the purpose of the class?

Question 2: What data or information does the class need to handle?

The second question revolves around the data or information the class needs to handle. Analyze the data attributes it should hold, as well as the relationships between this class and other classes in the system. Identifying the data/information the class handles will help to understand its responsibilities in processing, updating, and communicating this information within the system.
