Problem Statement:

Let's enhance Lab $10$ so that it includes reading input from a file & throwing exceptions. The program will read from text files above that you can download and displays the output as shown below. The program should throw FileNotFoundException exception if files is not in the current directory. In addition, the two custom exception classes $($InvalidHourlyPayException & InvalidHoursException$)$ should be created. See example in Section $12\mathrm{.}9$ Defining Custom Exception Classes. These exceptions should be thrown by the methods in the Employee class as shown on the UML diagram below and handled in the main class. The program should continue processing the data on the files only after verifying that the file exists, is not a directory, and can be read or exit if otherwise. Check methods in the File class such as exists$().$ isDirectory$(),$ canRead$().$ The program must close files that are opened.

Your program should do the following :

Start

create array with the list of input files $-$ Example $-$ String$[]$ myFileList $=\{"$empFile$1.$txt$",$ "empFile$2.$txt$",$"empFile$3.$txt$",$ "empFile$4.$txt$",$ "empFile$5.$txt$"\}$;

Loop until each file in the array is run

instantiate a File object

verify file exists, is not a directory, or is readable

instantiate an Employee object

instantiate a scanner object

Note: Inputs that generate exception, as highlighted in the UML, must be within a try$\{\}$ and catch $\{\}$ block individually or together

Loop until there is no more employee record in the file

read and set employee name

read and set employee ID

read and set employee shift $($input "day" $=$ true $,$ input "night" $=$ false$)$

read and set employee's hourly pay

read and set employee hourly pay

read and set hours the employee worked

display employee pay stub as shown in the example

End Loop

close opened file$($s$)$

End Loop

end

The program run should display the output shown below:

Employee Name: Ann

Employee ID: $661448$

Pay Period: Friday

Regular Pay: $$2000\mathrm{.}00$

Overtime Pay: $$75\mathrm{.}00$

Gross Pay: $$2075\mathrm{.}00$

Pay Period: Saturday

Employee Name: Don

Employee ID: $886898$

Pay Period: Saturday

Regular Pay: $$3960\mathrm{.}00$

Overtime Pay: $$5791\mathrm{.}50$

Gross Pay: $$9751\mathrm{.}50$

InvalidHourlyPayException: Invalid hourly pay rate: $0\mathrm{.}0$

InvalidHourlyPayException: Invalid hourly pay rate: $101\mathrm{.}0$

InvalidHoursException: Invalid number of hours: $0\mathrm{.}0$

InvalidHoursException: Invalid number of hours: $81\mathrm{.}0$

Thank you for using the total pay Calculator!

Good Bye!
