Composed$/$Aggregated Objects $$ Create a new class named LunchBag. LunchBag should

have data members of length, width, height, and a water bottle. All LunchBags have a bottle

holder that can hold a WaterBottle that can be purchased separately from the LunchBag $($so

it can be created in a main method and passed to the LunchBag class$).$

Additional Requirements

a$)$ A default LunchBag should have dimensions of $11\mathrm{.}2$L x $6\mathrm{.}1$W x $7\mathrm{.}9$H$.$

b$)$ There should be a default constructor that sets default values for the LunchBag. Create

a default WaterBottle in this constructor: setWaterBottle$($new WaterBottle$())$;$.$

c$)$ There should be a convenience constructor that takes four parameters that match all

data members in the order they are listed in the description above.

d$)$ All LunchBag data members should have an accessor and a mutator and all values

should be positive. If they are not positive, set them to their default values.

$$ This includes the WaterBottle data member which should also have an accessor

and a mutator.

e$)$ A LunchBag can hold a WaterBottle as long as the diameter is positive and less than or

equal to $4.$

$$ If a WaterBottle is set using the appropriate mutator method, an error message

should be printed if the WaterBottle cannot be stored and a default WaterBottle

should be used in its place.

$$ Note that an error message in the mutator is not the most appropriate

way to accomplish this. In Chapter $12,$ we will learn the correct way.
