Question $20(40$ points$)$

We want to implement a Builder design pattern with director $($not a Fluent Builder$)$ for a "FastFoodOrder".

The "FastFoodOrder" class has the following $4$ String attributes $($not a list $-$ separate fields$)$:

main, drink, side, dessert.

We need $3$ concrete builders to build the "FastFoodOrder" object as follows:

"KidsMealBuilder" class assigns the following values to the attributes of the "FastFoodOrder" object:

main $=$ "Chicken Burger"

drink $=$ "Apple Juice"

side $=$ "Chicken Nuggets"

dessert $=$ "Ice Cream"

"AdultMealBuilder" class assigns the following values to the attributes of the "FastFoodOrder" object:

main $=$ "Double Cheeseburger"

drink $=$ "Coke XLarge"

side $=$ "Onion Rings"

dessert $=$"Chocolate Cookie"

"DietMealBuilder" class assigns the following values to the attributes of the "FastFoodOrder" object:

main $=$ "House Salad"

drink $=$ "Coke Zero"

side $=$ "Broccoli"

dessert $=$ "Yogurt"

$>>$ What to Submit:

$------------------------------------$

$1.$ Give the UML class diagram.

Include only the pattern classes, do not add client. Auto$-$generated UML by IDE is not accepted. $(10$ points$)$

$2.$ Provide the implementation code of the designed UML class diagram in Java.

Using the implemented Builder pattern, write the client code $($Client$.$java$)$ to create $3$ representations of "FastFoodOrder" object $($created by each concrete builder$)$ and display the values of the attributes of the objects. $(30$ points$)$

HINT: You must have $7$ classes $(.$java files$)$

$------------------------------------$

$>>$ How to submit:

$------------------------------------$

For part $1,$ UML diagram, use "insert image" from the text box, to add your diagram. Submit an image $(.$jpeg, $.$png$,...).$ Make sure that you create the UML diagram using a UML tool. Any diagram submitted as paper screenshot or created by an image editor $($ex$.$ Paint, Photoshop,...$)$ will not be accepted.

For Part $2,$ Code Implementation, compress only all $.$java files as a $.$zip or $.$rar file and use "Add file" button below the text box to submit. Make sure you implement the client too, as requested and your code executes without any error.
