Elevens Lab Activity 7 Question 4c and tester class grading rubric​

​

Code for tester class(main method)

• Cards objects are created properly ( 6 cards) and added to the array of cards on a board - 5 points 

• Cards objects are created properly and added to the array of cards on the board, but array is not working properly -3 points 

• Cards objects  are created , but not added to the array of cards - 1 point 

• Cards are not created and array does not exists - 0 points

• Method cardIndexes is tested and works as defined - 5 points 

• Method printCards is tested and works as defined - 5 points 

Code for printCards method: 

•  Method is  created and  works as defined in the comment section  and prints all of the elements of cards that are indexed by cIndexes -  5 points

• Method is partially created, but does not print all the elements of cards that are indexed by cIndexes - 3 points  

• Some parts of the method are  created but does not work as defined in the comment section and does not print all elements of the cards that are indexed by cIndexes - 1point

• Method is not created  - 0 points  

Max points : 20 

   * Gets the indexes of the actual (non-null) cards on the board.

  

   * returns a List that contains the locations (indexes) of the non-null entries on the board.

  

It is important to understand how the cardIndexes method (Question 4c) works

​array

​ArrayList

​

Implement the body of cardIndexes method

Qestion 4c​

public List<Integer> cardIndexes() {

   

   

  }

Suppose that cards contains the elements shown in the previous slide.​

We will test this class later in the main class

The repl for the group work is provided on Google Classroom ​

Implement printCards method

Question 4d

Complete the following printCards method to print all of the elements of cards that are

indexed by cIndexes.

public void printCards( ElevensBoard board) {

List<Integer> cIndexes = board.cardIndexes();

/* Your code goes here. */

Implementing tester class

​

Create a tester class for both methods

Use the rubric provided (slide 2) for guidance

Good Luck!
