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. Assignment Evaluation Your assignment will be graded based upon all tasks being performed and handed in with all required documentation. Description Points Definition of the abstract DessertItem superclass 10 points Proper implementation of static variables for storing superclass cost and tax, as well as each individual derived cost and tax 10 points Definition of enumerated DessertType and use of switch statement to determine actions required 5 points Use of Arrays for storing up to 5 items of the four different DessertTypes. 5 points Definition of the Candy derived class 5 points Definition of the Cookie derived class 5 points Definition of the IceCream derived class 5 points Proper output of itemized purchases 5 points Integration of ItemsEntered method 5 points Proper implementation and use of NoItemsEnteredException 5 points Properly saving receipt information to Text file 10 points Proper Header and Source Code Documentation [Each class must contain proper documentation throughout both the class definitions and the application]
