WidgetMaker $-$ The constructor accepts three parameters, the machine$$s id $($a String$),$ the downtime

cost $($double$)$ and the number of days the machine has worked $($an int$).$ The instance variables are set for

the first two values as usual; the down time array should be initialized to an array the size of the

numDays parameter. Make certain your code will work whether numDays is short $($e$.$g$.13$ days$)$ or long

$($e$.$g$.365$ days$).$ Note, the class does not need a numDays instance variable; see the next method to

understand why not.
