For this lab you will modify your Lab $7$ to make several improvements to the getter$/$setter

methods. Instead of having them return True$/$False$,$ modify each one to throw an exception if

invalid data is passed.

Modify these methods in the following way:

$$ add$\_$hours$($x$)$

o If the number of hours being added is less than $0,$ throw an exception. Do not

change how the hours are distributed if the number of hours added is greater

than $0.$

$$ set$\_$employee$\_$number$($x$)$

o The employee number must be an integer. If the given input is not an integer,

throw an exception

$$ set$\_$office$\_$number$($x$)$

o If the office number given is less than $100$ or greater than $500,$ throw an

exception.

$$ set$\_$name$($x$)$

o If the given name is empty, throw an exception

o Any of the following characters should be removed from the name:

$\_,.,-($Underscore$,$ period, and dash$)$

$$ set$\_$birthdate$($m$,$ d$,$ y$)$

o If the given value for the month is less than $1$ or greater than $12,$ throw an

exception

o If the given value for the day is less than $1$ or greater than $31,$ throw a different

exception

You do not need to round or truncate your output. Name your class Worker
