Final answer:
The student needs to modify their Java worker class to include new attributes and methods for hourly and overtime salaries, and implement methods to set and get these salaries. The worker's total pay should also be calculated based on the hours worked, overtime hours, and salaries. A class file and driver file should be provided for testing purposes.
Step-by-step explanation:
The question is about modifying a class in Java, specifically the 'worker' class from a previous lab. The student is asked to add new attributes and methods to the worker class, including hourly salary, overtime hourly salary, and methods for setting and getting these salaries. The 'get_pay()' method should return the total pay of the worker, which is calculated based on the hours worked, hourly salary, overtime hours, and overtime salary. The student should provide a class file and a driver file to test every method.
