Thursday (10/17/19)

Agenda:

  • Did you complete Activity 6?
  • Iteration - While Loops
    • Basic while loops
      1. Write a loop that prints 0 to 10 (exclusive)
      2. Write a loop that prints 10 to 0 (inclusive)
      3. Write a loop that sums all the numbers from 0 to 1000 (inclusive)
      4. Write a loop that prints all the numbers that are divisible by 3 and 7 between 0 and 1000
    • While loops with strings
      1. Write a loop that prints each character of a String s (you supply the String's value)
      2. Write a loop that prints every other character of a String s
      3. Write a loop that prints each character of a String s from end to beginning
      4. Write a loop that counts the number of occurrences of a particular substring within a larger string (there are many ways to do this)
      5. Write a loop that prints the location of every occurrence of a particular substring within a larger string (there are many ways to do this!)
    • While loops with arrays
      1. Write a loop that prints every element of an int[]
      2. Write a loop that prints the square of every element in an int[]
      3. Write a loop that sums all the numbers of an int[]
    • Complete Test 6 and Test 7

Homework:

  • Complete Test 6 and Test 7 if you did not do so in class

Friday (10/11/19)

Agenda:

  • Activity 5 Questions?
  • Test 5 Questions?
  • Arrays Quiz

Wednesday (10/9/19)

Agenda:

  • Demo completed Tic-Tac-Toe game
  • Introduction to Arrays
    • Walk-through and read eIMACS: Arrays chapter (page 60)
    • Java Arrays
    • Complete the Canvas Arrays Practice assignment
    • Complete Activity 5: Arrays
    • Java Arrays Quiz on Friday (10/11/19)

  • Complete Test 5

Monday (10/7/19)

Agenda:

  • Demo Tic-Tac-Toe - Part 2
  • Tic-Tac-Toe - Part 3
    1. Be sure to create a new sketch so as not to lose your working Part 2 code
    2. Add conditionals to check if any 3 locations match (make sure that at least one of the locations is not equal to the empty string)
    3. Display a text() message that indicates the winner
    4. Call the noLoop() method to stop the game when there is a winner
    5. Implement a mechanism/conditional to check if the game is a draw (tie)
  • Demo a completed Tic-Tac-Toe game
  • Challenge:
    1. Implement an AI to play against you
    2. Design and implement Ultimate/Super Tic-Tac-Toe

Thursday (10/3/19)

Agenda:

  • Work on and complete Tic-Tac-Toe - Part 2
    1. Add a String variable to track the turn ("X" or "O")
    2. You have two options:
      • Add a two-dimensional String array to your Tic-Tac-Toe at the top to track the moves (all elements start as "", but will be "X" or "O" later)
      • Add 9 String variables, one for each Tic-Tac-Toe square. Use a naming convention like (b_0_0, b_0_1, etc.)
    3. Implement the appropriate code in mouseReleased() and draw() to draw Xs and Os where the mouse button is released
    4. Make sure that you also have conditionals to check whether or not the location that is clicked is still empty (check against 2D array)
    5. Make sure you update the 2-D String array OR your b_#_# variables with the current player's move
    6. Update the turn variable so that it switches after a player has successfully made a move
    7. Don't forget to update your draw() with text() commands so that all the moves are displayed
  • Done with the above? Here are some challenges:
    1. Implement a winner checking feature to stop the game and display who won
    2. Implement an AI to play against you
    3. Design and implement Ultimate/Super Tic-Tac-Toe

Tuesday (10/1/19)

Agenda:

  • Demo Tic-Tac-Toe: Select-a-Square
  • Read text() and test it out to draw some text on the screen
  • Read mouseReleased() and test out the code
  • X-O clicker assignment
    1. Modify the code of the mouseReleased() so that a text-based X or O is drawn every time the mouse button is released
  • Work on and complete Tic-Tac-Toe - Part 2
    1. Add a String variable to track the turn ("X" or "O")
    2. You have two options:
      • Add a two-dimensional String array to your Tic-Tac-Toe at the top to track the moves (all elements start as "", but will be "X" or "O" later)
      • Add 9 String variables, one for each Tic-Tac-Toe square. Use a naming convention like (b_0_0, b_0_1, etc.)

    5. Make sure you update the 2-D String array OR your b_#_# variables with the current player's move
    6. Update the turn variable so that it switches after a player has successfully made a move
    7. Don't forget to update your draw() with text() commands so that all the moves are displayed
