A Run the application. The Console should print out the behavior of the mallard duck.
Import the TurkeyService.
Acceptance Criteria
Acceptance criteria
  • The completed implementation satisfies this requirement: Write a line to the Console about testing the turkey.
  • The completed implementation satisfies this requirement: Call Fly and Gobble on the wildTurkey object.
Instructions
3.Import the TurkeyService.

Some animal enthusiast organization has asked that you incorporate their Turkey library and use them as ducks.

A Right-click on the References in your project and select 'Add Reference...'
B On the bottom right, click 'Browse...' and select the TurkeyService.dll from the zip provided.
C In the MainWindow after instantiating the MallardDuck...
1 Instantiate a WildTurkey object named wildTurkey after the MallardDuck.

You will need to add a using for TurkeyService.

2 Write a line to the Console about testing the turkey.
3 Call Fly and Gobble on the wildTurkey object.
4 Write out an extra line for spacing.
5 Write a line to the Console about testing the duck.
D Check Your Work:
1 Run the application. Your output should look like the output below.
Console: Output for 8.1 Adapter Pattern Lab. Use the adjacent task instructions to identify the required controls, output, or debugger values.
Console: Output
Line 1: Testing the turkey. . .
Line 2: I'm flying a short distance.
Line 3: Gobble gobble
Line 4:
Line 5: Testing the duck. . .
Line 6: I'm flying
Line 7: Quack
Build an adapter.
Acceptance Criteria
Acceptance criteria
  • The completed implementation satisfies this requirement: Remove the lines of code that call the turkey's Fly and Gobble methods.
  • Duck exposes the required contract: Fly(); Quack().
  • TurkeyAdapter exposes the required contract: TurkeyAdapter(turkey: ITurkey); Fly() override; Quack() override.
  • ITurkey exposes the required contract: Fly(); Gobble().
Instructions
4.Build an adapter.
A Try and test the turkey.
1 Remove the lines of code that call the turkey's Fly and Gobble methods.
2 Instead, call TestDuck and pass in the wildTurkey.

This isn't possible because TestDuck only takes IDuck types.

3 F12 on WildTurkey. You can't change anything about the class so no help there.
4 Remove the call to TestDuck.
B Add a TurkeyAdapter class based on the diagram below.
Class Diagram: TurkeyAdapter; Members and relationships are shown in the editable reference; unrelated members may be omitted.
Class Diagram: TurkeyAdapter
  • New
  • Changed
  • Removed
Class: Duck
Methods
+ Fly()
+ Quack()
Class: TurkeyAdapter
Inherits from Duck
Fields
- turkey : Turkey
Methods
+ TurkeyAdapter(ITurkey turkey)
+ Fly<override>
+ Quack()<override>
Interface ITurkey
Methods
Fly()
Gobble()
C In the TurkeyAdapter class...
1 Assign the turkey field to the turkey parameter in the constructor.
2 In the Quack method, call the turkey's Gobble method.
3 In the Fly method, write a for loop that calls the turkey's Fly method 5 times.
D In the Main method after the line that prints out about testing the turkey....
1 Instantiate a new TurkeyAdapter object named turkeyDuck and pass in the wildTurkey object to the constructor.
2 Call TestDuck and pass in the turkeyDuck.
E Check Your Work:
1 Run the application. Your output should look like the output below.
Output: Adapter Output for 8.1 Adapter Pattern Lab. Use the adjacent task instructions to identify the required controls, output, or debugger values.
