Chapter 12, Problem 1RE

Explanation of Solution

Steps in the process of object-oriented design:

Step 1: Gather program requirements.

  The development starts by collecting the requirements and its documentation.

Step 2: Discover classes.

The second step is to find the appropriate classes for the program. To find the classes, the user need to search for the nouns in the problem description.

Step 3: Determine the responsibilities of each class and identify collaborating classes.

In this step, use CRC card to determine the responsibilities of each classes ad their collaborating classes to solve these responsibilities.

Step 4: Determine the relationships between the classes.

In the fourth step, the user need to identify the relationships (Inheritance, Interface Implementation, Aggregation and Dependency) between the classes.

Step 5: Document the behaviour of classes using Javadoc comments.

In this step, the behaviour of the classes are documented using the “javadoc” comments.

Step 6: Implement classes.

  In the final step, the user should generate the code for implementing the classes.
