Description
The only Java class provided in the zip file attached to this Dropbox assignment is
ArrayList.java
Furthermore, in this coding problem the same List interface provided in HW#2 (i.e. the
SinglyLinkedList assignment) will be used, and under no circumstances are you allowed to
modify or create a new List interface. You must List interface as is.
You may only modify the ArrayList class. In particular, in the ArrayList class you may
only modify the methods listed in Part 1, and under no circumstances are you allowed to
remove, add, or modify any other line of code in this class (this include instance variables,
class variables, constants, etc.).
Lastly, you may not change the package structure! Specifically, edu.cofc.csci230
cannot be removed or modified. If a solution is submitted with a different package
structure, it will not be graded, no exceptions.
Part 1
In the ArrayList class please fully implement the methods listed below:
• public void add(int index, AnyType t) throws
IndexOutOfBoundsException
• public void set(int index, AnyType t) throws
IndexOutOfBoundsException
• public AnyType remove( int index ) throws
IndexOutOfBoundsException
• public AnyType get(int index) throws IndexOutOfBoundsException
• public void clear()
• private void grow()
• private void shrink()
In each method above, there is a TODO comment – this is where you add your code.
Please note (and testing hint): the functionality of the methods are identical to the ones
in the List interface defined in the Java API.
Part 2
The provided ArrayList class has a main method. In the main please add test cases
that demonstrate you have fully evaluated the operational correctness of the methods
implemented in Part 1. To receive full credit, these test cases must be included.
Submission
Create a zip file that only includes the completed ArrayList.java file (please do not
include any folders or any other project files in the zip file). If you have any questions
about the submission policy, please resolve before the due date. Lastly, please plan
appropriately, asking question the day the assignment is due (within 12 hours) is too late.
Please try to resolve any questions at least 2 days before the due date. The name of the
zip file must be your last name. For example, ritchie.zip would be correct if the
original coy developer of UNIX (Dennis Ritchie) submitted the assignment. Only
assignments submitted in the correct format will be accepted (no exceptions). Please submit
the zip file (via OAKS) to the Dropbox setup for this assignment by the due date. You may
resubmit the zip file as many times as you like, Dropbox will only keep the newest
submission.
Grading Rubric
ArrayList Compiles 10 points
ArrayList Runs 5 points
Thoroughness of your test cases 5 points
Instructor test cases (8 cases 10 points each) 80 points
100 points
In particular, the assignment will be graded as follow, if the submitted solution
• Does not compile: 0 of 100 points
• Compiles but does not run: 10 of 100 points
• Compiles and runs with no errors: 15 of 100 points
• Thoroughness of your test cases: 20 of 100 points
• Passes all 8 test cases developed by instructor: 100 of 100 points.
