Question
Please do not answer this question with an offer to do the answer in exchange for paypal payment.
Please DO BOTH PARTS (PART A & PART B) in order to get FULL 3000 points.
PART A)
Create an interactive applet which allows the user to run a simplified hotel check-out program.
You%u2019ll find that all the GUI components required by this applet program have already added in appropriate places in the HotelCheckOut.java file. All you need to do is to complete the program for the calculation of the total accommodation charges when a customer checks out from the hotel.
