9. Programming Project 6.18 asked you to use an array of Strings to store the fruits
and vegetables shipped in a
BoxOfProduce
object for a CSA farm.
Modify your solution further by creating a
Produce
class. This class should have an
instance variable of type
String
for the name, appropriate constructors, and a public
toString()
method. Then create a
Fruit
and a
Vegetable
class that are derived
from
Produce
. These classes should have constructors that take the name as a
String
and invoke the appropriate constructor from the base class to set the name.
Next, modify the text file of produce so it indicates whether each item is a fruit or
a vegetable. Here is one possible organization, although you can use others:
Broccoli,Vegetable
Tomato,Fruit
Kiwi,Fruit
Kale,Vegetable
Tomatillo,Fruit
Finally, modify the
BoxOfProduce
class so it creates an array of type
Produce
instead of type
String
. The class should read the produce from the text file and
create instances of either
Fruit
or
Vegetable
, with the appropriate name, in the
array. After a box is finished, loop through the contents of the array and output
how many fruit and how many vegetables are in the box. The rest of the program
should behave the same as the solution to Programming Project 6.18.
