Below attached you will find a file from Programming Challenge 5 chapter 6 with required you to write a Payroll class that calculates an employees payroll. Write exception classes for the following error conditions:

An empty string is given for the employees name.

An invalid value is given to the employees ID number. If you implemented this field as a string, then an empty string could be invalid. If you implemented this field as a numeric variable, then a negative number or zero would be invalid.

An invalid number is given for the number of hours worked. This would be a negative number or a number greater than 84.

An invalid number is given for the hourly pay rate. This would be a negative number or a number greater than 25.

Modify the Payroll class so that it throws the appropriate exception when any of these errors occur. Demonstrate the exception classes in a program.
