You will be creating TWO console applications.
Application 1
Create a Console application called “Ch4-Vending”. Add a class to the application called “VendingMachine”.This class will be composed
of one field (i.e., instance variable or attribute) and several methods as follows:
· A field of type int called “DepositedAmount” (ALL amounts are in cents, NOT dollars, so an int is appropriate here)
· A constructor that takes no parameters that simply initializes the machine’s DepositedAmount to 0.
· A method (no return value) called “DepositCoin” with a single int parameter called “coinAmount”
This method is intended to add the value passed in the coinAmount parameter to the machine’s DepositedAmount field. However:
(a) the method should check the coinAmount parameter to insure that it is either 5, 10, 25 or 100 (we have a cool machine that accepts
dollar coins) before adding the value to DepositedAmount. If it is not 5, 10, 25 or 100, the method should write “Error: Unrecognized
Coin” to the screen and the amount should NOT be added.
(b) regardless of whether anything is added to the DepositedAmount field, the method should conclude by displaying the current value of
DepositedAmount (e.g., “You have deposited XXX cents so far”).
· A method (no return value) called “GetDrink” with no parameters
This method does one of two things.
(a) If the machine’s DepositedAmount is is sufficient to cover the cost of a drink (125 cents or more), then the method calculates the
change (i.e., DepositedAmount less 125 cents), writes “Your change is {change amount} cents” to the Console, and then resets the
DepositedAmount back to 0 (simulating giving you back your change).
(b) If the machine’s DepositedAmount is not sufficient (less than 125 cents), it just writes “You must insert 125 cents” to the
Console.
· A method (no return value) called “GetRefund” with no parameters
This method does one of two things.
(a) If the DepositedAmount is greater than 0, it simply writes “You were refunded XXX cents” (the refunded amount should be the whole
DepositedAmount) and resets the DepositedAmount field back to 0.
(b) Otherwise, if the DepositedAmount is 0
Your Main method should create a single instance of your VendingMachine class. You should then call methods on this object to fully
test that the machine is functioning properly. No need to get input from the user. Just “hard code” instructions in your Main method.
Make certain that the code in your Main method adequately tests all methods with the vending machine in all possible states. For
example, you should insure that a call to DepositCoin does work with a correct coin but not with an incorrect coin. Certainly you
should also test to make sure that a call to GetDrink fails if there is insufficient funds and succeeds otherwise. Make sure that
GetDrink leaves the DepositedAmount alone if you don’t yet have enough for a drink but that it sets DepositedAmount to zero if you do
get a drink. Etc. Perform other tests as you deem necessary. Use the same VendingMachine object and just call the methods repeatedly to
test these scenarios. Leave all of your test code in Main so that I can see your work.
Application 2
Create a second Console application called “Ch4-Football”. Add a class to this application called “FootballTeam”. This class will be
composed of several fields (i.e., instance variables or attributes) and methods as follows:
· A field of type String called “Name”
· A field of type int called “Score”
· A constructor that takes a String parameter called “teamName”
The constructor simply initializes the Score field to 0 (zero) and the Name field to the value passed as teamName.
· A method called “ShowScore” with no parameters
This method writes “{Name} has a score of {Score}” to the Console. For example, if the team’s Name is “Augusta University” and their
Score is 24 then the method should write “Augusta University has a score of 24”.
· A method (no return value) called “ScoreTouchdown” with no parameters
This method adds 6 to the team’s Score field then calls ShowScore to display the current score.
· A method (no return value) called “ScoreFieldgoal” with no parameters
This method adds 3 to the team’s Score field then calls ShowScore to display the current score.
· A method (no return value) called “ScoreSafety” with no parameters
This method adds 2 to the team’s Score field then calls ShowScore to display the current score.
· A method (no return value) called “ScoreTwoPointConversion” with no parameters
This method adds 2 to the team’s Score field then calls ShowScore to display the current score.
· A method (no return value) called “ScoreExtraPoint” with no parameters
This method adds 1 to the team’s Score field then calls ShowScore to display the current score.
Use the Main method in your Program class to simulate this year’s BCS championship game between Alabama and Clemson. In other words,
create two object instances, one with a Name of “Alabama” and the other with a Name of “Clemson”. Then call ScoreXxx methods on the
appropriate instance to mimic the scoring of the game as summarized here:
http://espn.go.com/college-football/game?gameId=400852743 (Links to an external site.)
In the above summary, TD means touchdown and FG means field goal. Most TD’s are followed by extra points. However, note that one had a
failed 2-point conversion (i.e., no extra point).
At the end of your Main method, call the ShowScore on both instances. The last two lines of a correct program will display as follows:
Alabama has a score of 45
Clemson has a score of 40
As usual, the assignment should be submitted by compressing your solution folders to a .zip or .7z file and submitting them.
