A movie theater offers a package that typically consists of a movie ticket, a snack, a drink and a free gift, a patron must present a ticket to enter the theater, but snack, drink and free gift are optional. So the ticket can be decorated by snack, drink and gift. This gives patron flexibility to purchase any number of tickets and snack/drink, however, free gift is limited to 1 per package order. Each snack and drink can be multiple or partial. The cost of multiple or partial is adjusted proportionally. For example, cost of 2 coke is 2 x $2, half popcorn is 0.5 x $6 We would like to use the Decorator pattern and Singleton pattern to create the receipt to show order's item name, quantity, item unit price, item cost and final cost. The singleton is to ensure that a patron can get no more than one free gift for his/her order Here is the unit price of each item • Ticket, Adult: $10; Senior/Student: $8 Popcorn (decorator), $6 Chips (decorator), $4 Drink (decorator): Coke: $2; Sprite: $2 Gift (decorator): $0 (limited to 1 per order) 1) Give the UML class diagram.

A movie theater offers a package that typically consists of a movie ticket, a snack, a drink and a
free gift, a patron must present a ticket to enter the theater, but snack, drink and free gift are
optional. So the ticket can be decorated by snack, drink and gift. This gives patron flexibility to
purchase any number of tickets and snack/drink, however, free gift is limited to 1 per package
order. Each snack and drink can be multiple or partial. The cost of multiple or partial is
adjusted proportionally. For example, cost of 2 coke is 2 x $2, half popcorn is 0.5 x $6
We would like to use the Decorator pattern and Singleton pattern to create the receipt to
show order's item name, quantity, item unit price, item cost and final cost. The singleton is to
ensure that a patron can get no more than one free gift for his/her order
Here is the unit price of each item
• Ticket, Adult: $10; Senior/Student: $8
Popcorn (decorator), $6
•
Chips (decorator), $4
• Drink (decorator): Coke: $2; Sprite: $2
• Gift (decorator): $0 (limited to 1 per order)
1) Give the UML class diagram.
2) Provide the implementation code of the UML class diagram given in question 1) in the
programming language of your choice. In the client code, create an order that consists of 1
adult and 1 student tickets with 60% popcorn, 40% chips and 2 coke and 1 free gift.
The output should display item name, item quantity, item cost and final total cost on the
screen.
