  • Complete the Java Processing: Bouncing Ball Lab
  • Java References (if you feel like they'll be useful or you want to skim them to see what's there)

    • Convert your Python Processing Emoji to Java
    • Convert your Python Processing Hover Buttons to Java
    • Convert your Python Processing Tic-Tac-Toe to Java
  • If you do not have your Python Processing versions of the assignments above, then you may use somebody else's Python Processing code just to practice porting it to Java. You may find the Python version of some programs here
  • Make sure you successfully execute and test each of the programs that you convert over to Java
  • Feel free to practice converting other Python Processing programs to Java

Tuesday - Friday (3/17/20 - 3/20/20) : Self-distancing : Week 1

  • 3rd Quarter ends Friday (3/20/20)
    • All IB CS 1 grades are currently being entered for the 3rd quarter, so if you check and notice a grade is incorrect, then please e-mail Mr. Bui
    • Recheck your IB CS 1 grade daily because Mr. Bui is updating it right now.
    • If you wish to update a grade b/c you needed to complete a missing/late assignment, then please e-mail Mr. Bui
    • No work for 3rd Quarter will be accepted after Friday (3/20/20)
  • 4th quarter schedule of assignments will be posted soon (after Mr. Bui finishes closing out 3rd quarter grades)

Monday (3/16/20) : Self-distancing : Week 1

  • All students are still expected to have completed all the repl.its assigned when school was still in session last week (see previous date below)
  • Mr. Bui is developing a weekly schedule of Java-related programming tasks and resources. A complete schedule should be posted by Tuesday (3/17/20) morning
  • Mr. Bui is also developing a question-answer workflow so that students can ask general and specific questions. The workflow will look something like this:
    • General questions should be posted in the Canvas Discussion area; however, the student should check if any existing discussion threads already answer their question. If not, then a new thread should be created for their question
    • Specific questions about student code will require students to take a screenshot of their own code and message it to Mr. Bui. The Canvas messaging system will likely be used for this because Mr. Bui does not want his inbox to be flooded
  • If you have any questions right now, please feel free to e-mail Mr. Bui or create a Discussion thread. Please note that if you e-mail a question, and it's a good question, then Mr. Bui may create a thread himself to repost and answer your question
  • Please note: Mr. & Mrs. Bui have their own children at home with them, so do not expect immediate responses.
