What's New

• Dec 23: The feedback for Latest 3 is now available using Web Submit. Log in to Web Submit and select 1022 and assignment labtest3a or labtest3b. You should be able to see your submission and a link to your feedback.
  If you believe that there has been an error in the assessment of your Latest 3, you may submit a reappraisal request by Dec 30. To do this, fill out this reappraisal request form and then use WebSubmit to submit it (either as a text or PDF file), using the reappraisalLabtest3 assignment. After the request has been processed, our response will be posted in a file response.txt in the same WebSubmit directory as the reappraisal request.
  Before submitting a reappraisal request for Labtest 3, make sure you understand the feedback you received by running the tester (available on Moodle under Grades) on the file you submitted. Each multiple choice question is worth 1 mark and each programming question is worth 3 marks. The answer to each question either received full marks or 0; no part marks for having a part of the answer will be given. Two marks were deducted for submissions with compilation errors and one mark was deducted for invalid fromat answers to multiple choice questions as well as for submitting an entire project archive.
• Dec 23: Grades for Lab 3, 4, and 5 are now available on ePost here. Each of these labs was graded pass, i.e., 10/10, or fail, i.e., 0/10, according to whether it had been successfully demonstrated to the TA. One mark was deducted for failure to submit the app's source files by the deadline. You can see the files you submtted on WebSubmit. For Lab 5, one bonus mark, was given if the extensions in Section D5.4 Exercise 2 had also been successfully demonstrated.
  If you believe that there has been an error in the assessment of one of these labs, you may submit a reappraisal request by Dec 30. To do this, fill out this reappraisal request form and then use WebSubmit to submit it (either as a text or PDF file), using the reappraisalLabN assignment where N is the lab number. After the request has been processed, our response will be posted in a file response.txt in the same WebSubmit directory as the reappraisal request.
• Dec 10: The makeup labtest for students who missed any of the labtests (1, 2 or 3) due to illness or some other justified reason (you must have submitted a justification note) will be on Thursday Dec 13 at noon in WSC 106. If you have an exam conflict and cannot attend, email the instructor immediately.
• Dec 9: As mentioned earlier, the Final Exam will take place on Monday Dec 10 at 2pm in TC AVIVA. The exam will last 180 minutes and cover all the material we have seen this term, focusing on Java rather than Android. The format will be similar to that seen in the labtests, with 20 multiple choice questions and 4 programming questions. The multiple choice part and programming part have equal weight. Answers to the multiple choice questions must be entered on a Scantron sheet; please bring a HB pencil and an eraser. The answers to programming questions are written in pen or pencil on the exam paper. The exam is closed book, no aids allowed.
  The office hour on Monday Dec 10 will be at 11am instead of the usual 5pm. The office hour on Wednesday Dec 12 is at the normal time, 3pm.
• Dec 7: The feedback for Latest 2 evening version is now available using Web Submit. Log in to Web Submit and select 1022 and assignment labtest2b. You should be able to see your submission and a link to your feedback.
  If you believe that there has been an error in the assessment of your Latest 2, you may submit a reappraisal request within one week of the feedback being posted. To do this, fill out this reappraisal request form and then use WebSubmit to submit it (either as a text or PDF file), using the reappraisalLabtest2 assignment. After the request has been processed, our response will be posted in a file response.txt in the same WebSubmit directory as the reappraisal request.
  Before submitting a reappraisal request for Labtest 2, make sure you understand the feedback you received by running the tester on the file you submitted. Each multiple choice question is worth 1 mark and each programming question is worth 3 marks.

• Dec 5: The Final Exam will take place on Monday Dec 10 at 2pm in TC AVIVA. The exam will last 180 minutes and cover all the material we have seen this term, focusing on Java rather than Android. The format will be similar to that seen in the labtests, with multiple choice questions and programming questions. But the exam is pencil and paper, not on workstations. It is closed book.
• Dec 4: The feedback for Latest 2 morning version is now available using Web Submit. Log in to Web Submit and select 1022 and assignment labtest2a. You should be able to see your submission and a link to your feedback. The feedback Latest 2 evening version will be posted as soon as it is available.
• Nov 27: Labtest 3 will will take place during the lab sessions on Nov 30 (you must go to the section where you are registered). The test will last 90 minutes and will be held at the beginning of the lab period (don't be late). The test will cover the material we have seen on string and collections, i.e., Chapters 4 and 5 of the textbook. The format will be similar to that of the first two labtests. The test will focus on Java rather than Android.
• Nov 20: Instructions on how to get your Lab 5 graded during the lab session on Nov 23 have been posted below.
• Nov 11: Labtest 2 will will take place during the lab sessions on Nov 16 (you must go to the section where you are registered). The test will last 90 minutes and will be held at the beginning of the lab period (don't be late). The test will cover the material we have seen on control structures (selection and loops) and strings, i.e., Chapters 3 and 4 of the textbook. The format will be similar to that of the first labtest. The test will focus on Java rather than Android.
• Nov 9: If you believe that there has been an error in the assessment of one of your labtests or labs, you may submit a reappraisal request within one week of the feedback being emailed to you or grades being posted (whichever comes first). To do this, fill out this reappraisal request form and then use WebSubmit to submit it (either as a text or PDF file), using the reappraisalLabtestN or reappraisalLabN assignment as appropriate. After the request has been processed, our response will be posted in a file response.txt in the same WebSubmit directory as the reappraisal request.
  Before submitting a reappraisal request for Labtest 1, make sure you understand the feedback you received by running the tester on the file you submitted and reading the Nov 8 announcement about the grading scheme. The answer to each question either received full marks or 0; no part marks for having a part of the answer will be given.
  Lab 0 was graded pass, i.e., 10/10, or fail, i.e., 0/10, according to whether it had been successfully demonstrated to the TA. One mark was deducted for failure to submit the app's source files by the deadline. You can see the files you submtted on WebSubmit.
  Lab 1 received the grade of 10/10 if the features decscribed in Section D1.3 and those decscribed in Section D1.5 Exercises 1, 3, 4, and 5 had been demonstrated, the grade of 7/10 if only the features decscribed in Section D1.3 had been demonstrated, and 0/10 otherwise. One mark was deducted for failure to submit the app's source files by the deadline. You can see the files you submtted on WebSubmit.
  Lab 2 was graded pass, i.e., 10/10, or fail, i.e., 0/10, according to whether it had been successfully demonstrated to the TA. One bonus mark, was given if the extensions in Section D2.5 Exercises 5 and 6 had also been successfully demonstrated. One mark was deducted for failure to submit the app's source files by the deadline. You can see the files you submtted on WebSubmit.
• Nov 9: According to the original evaluation scheme, the 3 labtests each count for 10% of the course grade. Given that many students did poorly on Labtest 1, I propose to change the evaluation scheme so that each student's best two labtests each count for 12% of the course grade and the worst labtest count for only 6% of the course grade. No student would get a lower grade due to this modifcation. We will discuss this change at the Nov 12 lecture.
• Nov 8: Grades for Lab 0, 1, and 2 are now available on ePost here.
• Nov 8: Feedback on Labtest 1 has been emailed to students. The test was graded out of 20. Each multiple choice question was worth 1 mark and each programming question was worth 3 marks. The test was graded by running a tester like the one provided during the test but with a few additional test cases. The tester for the morning test is here and the one for the evening test is here. You can see/retrieve the files that you submitted by using the WebSubmit app and selecting the labtest1a assignment for the morning test and labtest1b for the evening one. You can run the tester on your submission. Submissions with compilation errors received a grade of 0 (as indicated in the test instructions). One mark was deducted if the Utilities.java class was in the wrong package. One mark was also deducted if the submission contained a project archive rather that just the Utilities.java class.
  The procedure for requesting a regrading of your Labtest 1 will be announced shortly. Do not send email to the TAs or the instructor concerning this.
• Nov 7: Course grades will be posted here.

• When the teaching assistant (TA) comes to your workstation, demonstrate to the TA that your implementation of the Caps app meets the specification as described in Chapter 5 - Doing - Collections, Sections D5.1 to D5.3 inclusively of the textbook and works correctly on a WSC lab workstation and a tablet. Doing the above (and submitting your files) is sufficient to get full marks. However for a 10% bonus, also demonstrate to the TA that you have successfully implemented the extensions in Section D5.4 Exercise 2 where you generate different tones when a question's answer is correct and when the answer is incorrect. The TA will record that you have demonstrated that your app works. You must complete this task well before the end of the lab period! When the lab period ends, everyone must leave, and it will be too late.
• Submit your app files for grading. To do this:
  • Locate the src folder of your Caps app (it should be in folder AndroidStudioProjects/Caps/app) and compress this src folder using the zip utility, and name the resulting file Caps_src.zip. (In the lab's system, you can compress a folder by right clicking on it and selecting "compress".)
  • Open the link https://webapp.eecs.yorku.ca/submit in your browser, login using your Passport York account, select your course 1022, select your assignment lab5, choose the file Caps_src.zip, and then click the "Submit files" button at the bottom of the page. If you have successfully completed this task, you will see a message saying that you have submitted the file Caps_src.zip with the submission time. You can submit as many times as wou want and only the last version submitted is kept. You must complete this task by 23:59 on Nov 23..
