HW01: Learning git and Other Stuff due Mon 23 Jan 10:00

Upon completion of this assignment you should:
...t homework submission procedures for
this course


You may find it helpful to review some of the lessons in the “And All the Other Stuff” course that you went through for prelab. Feel free to return to as many of those lessons as you find helpful.

This assignment will be different than most in that the programming portion will be relatively easy. The biggest challenge of this assignment will be to learn how to properly submit homework assignments.

For most homework assignments you will update your shared, hosted git repository prior to the due date/time. You will not need to submit anything in Canvas unless instructed to do so in the assignment. When I grade your work I will leave feedback in Canvas and possibly also in your shared repository.

IMPORTANT: Each homework assignment assumes you have completed its corresponding lab day requirements prior to starting the assignment. You should take the time to complete the lab day exercises before you start the homework.


Upon completion of lab day #1 you should have made and committed a change to a local repository and those changes should be updated in your hosted BitBucket repository. As part of the pre-lab assignment you set up a workspace where you plan to do homework. Go to that workspace and begin by pulling the changes you made during the in-lab session: git pull mine master Verify that your local workspace matches what you did during the lab. Now you are ready to do your homework. NOTE: If you did your in-lab work on your own computer then the above step will not be necessary.

Edit the Java source code and add a new method called searchByYear that accepts the three arrays as parameters along with the number of elements in the arrays. It will not return any values. Leave the body of the method blank except for a single print statement that gives a message “Search by Year”. Do, however create a comment that conforms to JavaDoc requirements (see other comments as examples). As part of your homework assignment you will actually complete this method. For documentation purposes you need to know what this function will do: prompt the user to enter a year and display all movies that match the given year.

NOTE: A method that has a defined header but that does nothing is called a “stub” method.

If you look at the method called menuChoice you can see that the user is prompted to enter a value of 6 to select the “Search By Year” action. In main() (inside the while loop) add an if-statement that will call the mostly empty searchByYear method in the event the user entered a at the menu. Compile, test, and tweak as necessary to get the changes you made to work. When the user enters 6 at the menu they should see the output of the single print statement in the new searchByYear method.

It is time to commit your changes. Remember the sequence:

  1. git status (to see what has changed)
  2. git add xxxx (as necessary to stage changed/new files to be committed)
  3. git status (to verify everything you want to commit is in the staging area)
  4. git commit -m "Explain what you are committing" (to commit the changes)
  5. git status (to verify everything committed as you expected)
  6. git push mine master (to upload the current changes to your BitBucket account)

Go ahead and fully implement the searchByYear method so it works. When displaying matching entries you can copy the printf statements in the displayAll method. For testing purposes you may find it helpful to add some statements in main() that will put three or four movies into the parallel arrays so you don't have to enter movie information each time you run the program.

Once your method is fully tested and deemed to be working commit your changes to the local repository with a message that indicates you have finished the first homework assignment. Then push your changes to your hosted repository.

Submission Guidelines

The assignment will be graded according to the following criteria:
Correctness 10 pts
Documentation 2 pts
Conventions 2 pts
Version Control 2 pts
Total 16 pts

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.
