you are not writing a FoodApp application. It doesn't need to DO anything. All you need to do is create the shell Java classes, with the needed instance variables and shell methods. The methods don't need any code; the program doesn't need to compile or run.

If you DO want the program to compile (but not run, obviously), you may want to add some dummy return values like:

double getTitalCost() { return 0.0; } 

UML and Java 1. UML to Java Review the following UML Design. Create the Java classes which correspond to these designs. As always, you will need to create one Java file for each class you will be implementing. You do not need to add code to the methods but each method that is supposed to return should return a value of the proper type. For example: int getintval() { return 0; } String getStringVal() { return ""; } MyClass getClassval() { return null; } void noReturnval() {} OrderApp FoodOrder -orderNumber: long +additem(i: Menuitem) +get TotalCost(): double Customer -name: String +chargeCreditCard(): void 1 +main(args: String): void Menuitem +name: String #price: double +getPrice(): double ComboMeal -discount: double +getPrice(: double +additem(i: Menuitem); void Notes: Turn in all source files. There should be five. Make sure your classes are not in a package (that is, they are in the default package). Your source code should all be syntactically correct (no errors). Pay attention to the type of relationship between classes and implement each one appropriately. Watch multiplicities and access specifiers! 2. Java to UML Review the following Java Code for the children's card game called "War". Create the UML class diagram which corresponds to this code. Make sure to account for all the classes, attributes, methods, relationships, access specifiers and multiplicity. You can draw this out by hand and take a picture (be legible!) or use a modelling tool. I use StarUML which can be downloaded for free.

Pay attention to the type of relationship between classes and implement each one appropriately. Watch multiplicities and access specifiers
