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

  • 3rd Quarter ends Friday (3/20/20)
    • All AP CS grades have been entered for the 3rd quarter, so if you check and notice a grade is incorrect, then please e-mail Mr. Bui
    • 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 3 of the AP CS FRQs that were assigned when school was still in session last week (see previous date below). Be prepared to take pictures or scan your work to submit to Canvas. More details to come...
  • Mr. Bui is developing a weekly schedule of Java-related, AP CS review tasks and resources. {{strikethrough|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 a questions, 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

Friday (3/13/20)

Agenda:

  • You will be practicing AP CS FRQs today
    • Complete #1, 2, 4 (skip #3) of the 2018 AP CS FRQ
    • You must write your responses by hand (make sure your name and the question numbers are at the top)
    • You may use the AP CS Java Quick Reference
    • Spend no more than 22.5 minutes per question

Homework:

  • If you do not complete the 3 FRQs in class, then you may work on them at home

Wednesday (3/11/20)

Agenda:

Monday (3/9/20)

Agenda:

  • Recursion quiz
  • APCS FRQ 2019 #3 grading rubric
  • Merge sort
    • Possible MC question where they ask you to trace a merge sort execution
  • Quick...
    1. Create a two dimensional array of type double (4 x 6)
    2. Populate the 2D array with random numbers from 0 to 100
    3. Write a nested for loop that sums the entire 2D array and calculates the average

Homework:

  • APCS FRQ 2019 #4 (22 minutes)

Thursday (3/5/20)

Warmup:

Given the following method declaration, which of the following is printed as the result of the call mystery(1234)?

//precondition:  x >=0
public static void mystery (int x)
{
   System.out.print(x % 10);

   if ((x / 10) != 0)
   {
      mystery(x / 10);
   }
   System.out.print(x % 10);
}

(a) 1441
(b) 43211234
(c) 3443
(d) 12344321
(e) Many digits are printed due to infinite recursion.

Agenda:

  • Finish APCS FRQ 2019 #2 (5 minutes)
    • Self-grade rubric
  • Recursion quiz on Monday (3/9/19)
  • Recursion review & HW questions?
  • Recursion practice problems
    • Write a recursive method that returns the sum of all the numbers from N down to 1: int sum(int N)
    • Write a recursive method that prints every other letter of a string: void printSkipping(String s)
    • Write a recursive method that returns true if a particular character is in the String: boolean findChar(char ch, String s)

Homework:

  • APCS FRQ 2019 #3 (22 minutes)
