Table 10-1 PasswordException Class Development Tasks
DEVELOPMENT PHASE TASK(S)

1 Analyze the requirements Analyze the PasswordException class problem.

2 Design the solution Design the logic to solve the problem.

3 Validate the design Confirm with the user that the design solves the problem in a satisfactory

manner.

4 Implement the design Translate the design into code. Include internal documentation (comments

and remarks) within the code that explains the purpose of the code
statements. Design and code the StockListDemo application used for testing
the PasswordException class and subclasses.

5 Test the solution Using the StockListDemo test application, test the PasswordException classes.

Find and correct any errors (debug) until they are error-free.

6 Document the solution Print copies of all source code, including the test program code.
