Description
Implementation
This section further describes each class method found within the UML diagram.
Class Employee· get/setName gets and sets the
employee's private name variable. Be sure to filter out bad input, such as
empty strings.· get/setEmployeeId gets and sets the
employee's ID number. Be sure to filter out ID numbers that are less than or
equal to zero.· set/isWorking sets and gets whether
or not the employee is working. No filtering is required.· toString returns a tab-delimited
string in the following format: "name \t id \t is working"
Class StudentEmployee· get/setPayRate gets and sets the
employee's pay rate. Be sure to filter out negative values.· get/setHoursWorked gets and sets
the hours worked for the current week. Be sure to filter out negative values.· getWeeklyPay computes the student's
weekly pay. To calculate, multiply the number of hours worked times the pay
rate.· set/isWorkStudy sets and gets
whether the student is work study.· toString() returns a tab-delimited
string in the following format: "name \t id \t is working \t hours worked
\t is work study \t pay rate"
Testing Our Classes
Use your main function to test the StudentEmployee class. In main, prompt the
user for a CSV (comma separated value) file to open. Then, using the provided
StringSplitter class, split the CSV using the comma as a delimiter and use the
data to create a new StudentEmployee. Finally, output all StudentEmployees onto
the screen.

Explanation & Answer
Thank you for the opportunity to help you with your question!
in general, do not need to be licensed or pass any standardized (or governmentally regulated) certification tests in order to call themselves "programmers" or even "software engineers.
