Part 1: Create CheeseShop.java The machine will dispense 3 types of cheese, in half-pound packages. The types of cheese and prices are as follows: Humboldt Fog: $25.00 per pound Red Hawk: $40.50 per pound Teleme: $17.25 per pound Your program will do the following: List all the cheese types available and the prices. Asks the user how many pounds of each type of cheese to purchase in 0.5lb increments. . Validate the input to be >= 0 and to be in 0.5 lb increment for positive amounts. Calculate discounts based on how many pounds for each type of cheese the user entered o Discount for Humboldt Fog is that for each 0.5 lb package the user gets another 0.5 lb package for free. o Discount for Red Hawk is that for every two 0.5 lb packages, the user gets a 0.5 lb package for free. o See Discount Calculation below for details. Calculate Sub Total (price * amount of each cheese added together). Ask the user if they would like to see a list of what they purchased. o If the user answers yes, a list comes up showing how much of each type of cheese they bought and the cost of each cheese. Display only the cheese they actually bought. o If no items are purchased, then display a message stating the same (see Sample Run 6). o If the user answers no, then no itemized information is displayed. Display Sub Total, Discount(s) and Final Total. See Discount Calculation below to see how these are calculated Discount Calculation The Humboldt Fog and Red Hawk cheeses are offered at the following special promotions: Humboldt Fog: Buy 1 package get 1 package free Red Hawk: Buy 2 packages get 1 package free where, each package is 0.5 lb. Depending on how much of Humboldt Fog or Red Hawk chesses are bought, we will remove the cost of the free packages from what the user originally bought when calculating the Final Total. For instance, if the user bought 2 lb of Humboldt Fog (4 packages), then 2 of these packages will be free. And if the user bought 2 lb of Red Hawk (4 packages), then 1 of these packages will be free. You may think of the technique of calculating these discounts as marking every 2-package as free for Humboldt Fog, and marking every 3 package as free for Red Hawk. In the table below, the blue cells indicate the free Humboldt Fog packages in a 4.5 lb order giving you 4 packages (or 2 lb) for free. Similarly, the orange cells indicate the free Red Hawk packages in a 4.5 lb order giving you 3 packages (or 1.5 lb) for free.
