lntroduction:
As a pay roll manager, you determine that ,you need a^ quick way,^ outside^ of^
-excel, to
determine yourt'einployees' expected^ weekly^ pay^ given'their pay^ level^ and the number^ of
hours they work in^ a^ week.
How it works:
Each employee is represented by'ai"Employee object.^ The program^ you^ will^ build^ uses^ an arraylist (not^ array) to contain Employee^ objects^ to^ which^ the^ attributes^ df^ first^ name, last name and pay^ level^ are,ascri6ed.^ This^ object^ class^ will^ have^ a^ PI/BLIC^ function^ that
returns the employee's Weekly Salary by^ detefmining how many hours^ of^ a^ given^ week
are Regular Time (in^ our^ case,^ hours^0 thru^ 40)^ and^ Oier^ Time (any work^ beyond 40 hours)..^

The Emplo,yee objects are storedln an arraylist and^ are^ called^ upon to^ update^ a^ listview^ of^ '
the employee names. Output^ oT^ hours worked is^ in^ the^ fo'rm^ of^ a^ messagebox'. Pay rates for given pay^ levels are as follows:.

f,he GUI:
' ;^
-t' ' 'The ; GUI has I groupbbx,4 labels, 3 textbox6s, 2 buttons,^1 combobox,^ and^ one^ listview.
. ,You,'must^ add i-h".oln.nns to the listview in desi$n rhode, and'into the combbbox you
must add the default^ text^ as^ well^ at^ the^ following"selectable^ itehs:^ Executive,^ Mid-Level
oManager, and New Hire, in that orddr. See walkthrough to check for correctness.
lset the listview-so that ENTIRE ROWS are selectable, not.-- just^ indivihud cells.

PROGRAM CHECKLIST:
o Be sure to adherdto every requirement for the Add button (under^ Form Controls).
o There is no error checking for nonsense inputs or an invalid selected index in the listview.
o Pay careful attention to the^ messagebox^ generated^ by^ the^ report button^ (see walkthrough). Be sure that the formats match up, and notice that the dollar output is formatted. Don't worry^ about using^ floor^ or^ ceiling^ on this^ value.
o Your program MUST use the object class given; WeeklySalary MUST be public, and calls on RegularTime and OverTime, which MUST be private.
o Be sure to set the listview so that when clicked, an entire row is selected and not just^ an
individual cell (see walkthrough). It is okay for the "selection" appearance to go away
when you^ click outside of the listview. The selected index remains.
PROGRAM WALKTHROUGH: Your program^ should behave exactly as follows!
