Stage 3: Prompt the user for a receipt file name, write the contents of the receipt to the text file

. The objective of this third stage is to save the receipt information to a text file.

Stage 3: Task(s) The objective of this third stage is to enhance the application developed in stage 2 to prompt for a filename to store the receipt information. Upon entering the receipt, the receipt contents developed in stage 2 will be output to the text file.

The application should create a NoItemsEnteredException. The application should create a static method called itemsEntered which returns the total number of items purchased. If there are no items, the method should throw the NoItemsEnteredException.

heres sample output

Peanut Butter Fudge $ 8.98 [Tax: $0.63] 2.25 lbs @ $3.99 Candy Cane $ 0.75 [Tax: $0.05] 0.50 lbs @ $1.50 Oatmeal Raisin Cookies $ 1.33 [Tax: $0.09] 4 cookies @ $3.99 per Dozen Chocolate Chip Cookies $ 4.25 [Tax: $0.30] 12 cookies @ $4.25 per Dozen Vanilla Ice Cream $ 2.75 2 scoop(s) @ $1.05/scoop + $0.65 Cherry Garcia Ice Cream $ 5.29 3 scoop(s) @ $1.33/scoop + $1.30 CANDY [ 2] Cost: $ 9.73 Tax: $0.68 COOKIES [ 2] Cost: $ 5.58 Tax: $0.39 ICE CREAM [ 2] Cost: $ 8.04 ---- -------- ----- Subtotals [ 6] $23.35 $1.07 ======== Total $24.42
