Exception Project

This assignment assumes you have completed Programming Challenge 1 of Chapter 10 (Employee and ProductionWorker Classes). Modify the Employee and ProductionWorker classes so they throw exceptions when the following errors occur:

• The Employee class should throw an exception named InvalidEmployeeNumber when it receives an invalid employee number.

• The ProductionWorker class should throw an exception named InvalidShift when it receives an invalid shift.

• The ProductionWorker class should throw an exception named InvalidPayRate when it receives a negative number for the hourly pay rate. Write a test program that demonstrates how each of these exception conditions works.

Reference: Programming Challenge 1 :

Employee and ProductionWorker Classes

Design a class named Employee . The class should keep the following information in fields:

• Employee name

• Employee number in the format XXX–L, where each X is a digit within the range 0–9 and the L is a letter within the range A–M.

• Hire date

Write one or more constructors and the appropriate accessor and mutator methods for the class.

Next, write a class named ProductionWorker that extends the Employee class. The ProductionWorker class should have fields to hold the following information:

• Shift (an integer)

• Hourly pay rate (a double )

The workday is divided into two shifts: day and night. The shift field will be an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write one or more constructors and the appropriate accessor and mutator methods for the class. Demonstrate the classes by writing a program that uses a ProductionWorker object.
