write an application that displays a menue of three items in a restaurant as follows: 1.Cheeseburger 4.99 2.Pepsi 2.00 3.Chips 0.75 prompt the user to choose an item using the number (1,2,or 3) that corresponds to the item, or to enter 0 to quit the application.after the user makes the first selection, if the choice is 0, display a bill of $0.otherwise,display the menu again.the user should respond to this prompt with another item number to order or 0 to quit.if the user types0,display the cost of the single requested item.if the user types 1,2 or 3 add the cost of the second item to the first, and then display the menu a third time.if the user types 0 to quit,display the total cost of the two items;otherwise,display the total for all three selections.save the file as FastFood.java

B. modify the application in Exercise above so that if the user makes a menu selection he or she has already made, ignore the selection-that is,do not add a second price for the same item to the total.the user is still allowed only three entries.save the file as FastFood2.java
