HW02: Parallel Arrays: Search/Delete due Mon 29 Jan 10:00

Allowed and Disallowed Resources

• The Java Command Sheets handed out in class (and also available here: https://josephus.hsutx.edu/classes/all/commandsheets/).
• Examples and sample code found here: https://josephus.hsutx.edu/classes/p2/source/. NOTE: The same examples can be cloned from this repository: https://tsergeant@bitbucket.org/tsergeant/p2_examples.git
• A Java compiler with or without an IDE. The text editor you use can provide syntax highlighting, but must not generate code.
• Video instructions provided in Canvas as part of this course. You MAY NOT USE any other video resources.
• The course notes that accompany the video instructions which can be found here: https://josephus.hsutx.edu/classes/p2/coursenotes.php
• The official Java Documentation found here: https://docs.oracle.com/en/java/javase/21/
• Any handouts provided by the instructor as part of this course.
• Your own course notes
• Your instructor
• Discussions about the assignment with other students as long as you never look at the code produced by another student and you never receive instructions about solving the homework. That is, discussions need to be about concepts and understanding the technologies and not about how to solve the particular problem posed in this assignment.

You may NOT use/access:

• Resources not expressly listed above, including, but not limited to, the following ...
• Source code not provided as part of this assignment. (Obviously, this includes, but is not limited to, source code written by other students whether current or in the past).
• Code-generating tools (of which ChatGPT is one example).
• Any web sites not directly linked to from the homework assignment.

Failure to abide by these guidelines will result in a zero for the assignment and the incident will be reported to the university provost as a violation of the university academic integrity policy. A second incident of academic dishonesty (whether from this course or another computer science course) will result in an F in the course.

Overview

Details

1. Make sure your local working repository has all of the changes reflected in your hosted repository and the base repository (git pull mine master and git pull origin master).

2. Implement the method that will search by title. You will ask the user to enter a title to search for. Your search should be a forgiving search in that:
   • it should be case insensitive
   • it should do partial matching ... if the user entered “th” as the search string it should match the title “The Cat's Meow” and the title “Fun on 10th Street”.

3. Once the search by title is working perfectly and has been documented using JavaDoc conventions commit your changes to the local repository along with an accurate, descriptive message.

4. Implement the method to search by genre. The search here should be case insensitive but, otherwise, should require an exact match.

5. Make sure the method is properly documented and commit your changes locally.

6. Implement the delete method.
   1. Begin by having the user search for a title to be deleted. Since you already have a method that searches by title just call that method. Modify your search method so that when it prints titles it also displays the array position where the title is found.
   2. Ask the user to enter the id (i.e., array position) of the title they want to delete.
   3. Remove the title (and genre and year) from the array if the number given by the user exists.

7. Make sure the method is properly documented and commit your changes locally.

8. Implement the save method and call it after the loop in main().

9. Make sure the method is properly documented and commit your changes locally.

10. Do a final check of the behavior of the program. Test it more fully by switching the datafile from tinymovielist.txt to movielist.txt. Commit any tweaks or changes you have made indicating in your message that this homework assignment is complete.

11. Push your changes to your hosted repository.

Submission Guidelines

Your program should be completely working and should follow all of the programming conventions named in class and explained in http://josephus.hsutx.edu/classes/all/javaconventions/ (including the use of comments that conform to the JavaDoc guidelines).

The instructor will grade your work based on what you have pushed to the hosted homework repository you have shared. For all assignments the program is due before the beginning of class on the due date. Repositories that show a commit time after that time will be graded as late.
