Final Project Planning

 

Next Class: 2 FRQs

 

Discuss Daily Schedule FRQ

CodingBat: 15 questions from the AP-1 set. Complete by 3/17

Free Response Question-Daily Schedule

Practice Free Response Question Exercise

Picture Lab QuickCode: Write two unrelated methods for the Picture class. Full value if complete by 11:45.

Picture Lab Chromakey: Write a chromakey method that replaces the current pixel color with the color from another picture at the same row and column when the current pixel color is close to a specified color. In many movies, the actors are filmed in front of a green screen and then the green is replaced with a different background using a similar technique. This is an ungraded challenge problem

Continue Picture Lab: Inheritance Discussion and continue working through PictureLab

 

Picture Lab: Steganography-Steganography is the science of hiding information in a picture. You can hide a black and white message inside a color picture by first changing all the red values in the original color picture to be an even value (by subtracting one if odd). Make a picture of the same size out of the message that will be hidden. Then loop through both the original picture and the message picture, setting the red value of a pixel in the original picture to odd (by adding one to it) if the corresponding pixel in the message picture is close to the color black. Write an encode method that takes the black and white picture message and changes the current picture to hide the message picture inside of it. Then also write a decode method that returns the picture hidden in the current picture.

Steganography Graded Projects-

Quickcode- Using the files in the Inheritance QuickCode folder in the common drive, create EquilateralTriangle and RightTriangle classes that are derived from the abstract Triangle class. Provide an appropriate constructor for each of the classes and make them call the superclass's constructor. Redefine the abstract methods appropriately in the derived classes. Complete the declaration statements in the TriangleTester class. Compile all classes and run the TriangleTester. Full Value if complete by 12:00

Design and implement a class called MonetaryCoin that is derived from the Coin class from Chapter 4. Store a value in the monetary coin that represents its value and add a method that returns ts value. Create a main driver class to instantiate ten coins. Flip each coin and return the sum of the coins that show heads.

Fall Final Exam Review Sheet: The linked document contains the topics that may be tested on the Final Exam.  Review the list and ask questions about any topic that you do not understand.

ArrayList Quickcode- Using the files in the ArraylistQC folder in the common drive, complete the employeeIsEligible() and processRetirements() methods of the Company class. Full value if completed by 11:55.

You should not need to change any class other than the Company class, but you will need to compile the other classes.

Use the CompanyTester class to check that it works correctly.  An employee is eligible for retirement if (s)he meets at least two of the following requirements.

 

Method processRetirements removes all retirement-eligible employees from ArrayList myEmployees and maintains the following conditions: the ArrayList is maintained in order by employee ID and myTotalSalary is the total of all salaries of the remaining employees.

Writing Classes Quiz

Work on Chapter 4 Programming Projects

Chapter 4 Multiple Choice Questions discussion

Programming Project 4.6: Design and implement a class called Card that represents a standard playing card. Each card has a suit and a face value. Create a program that deals 20 random cards.

Classes: Association, Aggregation, Inheritance, Encapsulation
Classes: Method and Constructor Overloading

Chapter 4 Multiple Choice Questions

Programming Project 4.3: Write an application that rolls a die and displays the result. Let the user pick the number of sides on the die. Use the Die class from the common folder to represent the die in your program.

Programming Project 4.4: Design and implement a class called PairOfDice, with two six sided Die objects. Create a driver class called BoxCars with a main method that rolls a PairOfDice 1000 times, counting the number of box cars (two sixes) that occur.

Programming Project 4.3: Write an application that rolls a die and displays the result. Let the user pick the number of sides on the die. Use the Die class from the common folder to represent the die in your program.

Midterm Review Grid: Page 2

Midterm postponed to Friday 10/17 because of the PSAT

Grading Period ends Friday:

• CodingBat: Recursion-1
• CodingBat: String-2
• Textbook programming projects 3.6,3.10,3.14
  • 3.6: Design and implement an application that determines and prints the number of odd, even, and zero digits in an integer read from the keyboard.
  • 3.10: Design and implement an application that plays the Hi-Lo gueesing game with numbers. The program should pick a random number between 1-100 (inclusive) then keep asking the user to guess the number. On each guess, report correct, high, or low. Use a sentinel value to determine whether the user wants to quit. Count and report the number of guesses. Give the user the option to play again.
  • 3.14: Design and implement an application that plays rock-paper-scissors against the computer. The program should randomly choose  an option and then ask for the user's selection. The program then reveals both choices and displays the result. Keep playing until the user chooses to stop then print the number of user wins, losses, and ties.
• Iteration Quiz on Thursday 10/8
• Midterm on Wednesday 10/14
• End of First Quarter Friday 10/16

Checking Work for Progress Report: By end of period, bring up on screen:

• QUIZ: Conditionals and String methods.
• Magpie Chatbot lab Activity 4.
• Magpie Lab Graded Activity: With a partner, design and implement an upgrade to Magpie4. Write the intended modification and names of both students in comments at the top of the code before you begin coding. Your upgrade should add significant new vocabulary to what Magpie can understand. The code only needs to be in one students folder. (due by Friday, 9/18)
• CodingBat continued: Complete at least 10 exercises from from each section: Warmup-1, String - 1, Logic-1
• Next Class: Introduction to Recursion. Make sure that you have finished the reading from Think Java and Chapter 8

 

Copy Magpie Lab Folder from Common Drive to your G: Drive

Open the Magpie Lab Student Guide

Activity 1: Getting Acquainted with Chatbots. Work with a partner to experiment with chatbots. Be prepared to discuss the answers to the questions in the activity. http://sites.google.com/site/webtoolsbox/bots

Activity 2: Introduction to the Magpie Class. Open the Magpie2.java and MagpieRunner2.java files using jGrasp. Compile both classes. Complete Activity 2.

Following the class discussion on math operations and the use of the Scanner class:

 

Programming Projects 2.2, 2.3, 2.6, 2.7

 

2.2 Write an application that reads three numbers and prints their average

2.3 Write an application that reads two floating point numbers and prints their sum, difference, and product.

2.6 Write an application that reads values representing a time in hours, minutes, and seconds. Then print the same time in seconds

2.7 Write an application that performs the reverse of 2.6. Read a value representing a number of seconds then print the same amount of time in hours, minutes, and seconds.

Discussion: String Class

Discussion: Anatomy of a method

Programming Projects 2.8,2.12

CodingBat: 10 problems each from Warmup-1, String-1, and Logic-1

Syllabus Verification Form - This form must be returned with parent signature. 20 points by due date. 15 points if late

Read Chapter 1 of Blown to Bits

Blown to Bits part 2: Google Groups: Select at least 3 of the Koans from Chapter 1 of Blown to Bits. Post an example of what the Koan means. Do not use examples that are directly from the article.

Read sections 1.0 through 1.2 in the textbook

Inside the Computer Project: Describe how a computer works in two different ways.

Method 1: Words
Write a description of how a computer works. Do not need to be literal, but instead
demonstrate an understanding of the processes and logic involved in the internal
operation of the computer in non computer terms. You may not use any of the words on the restricted list below and you may only use the words “computer,” “device,” and
“system” three times each.
Restricted terms list: CPU, Central Processing Unit, Memory, RAM, ROM, Bit, Byte,
Chip, Motherboard, Drive
Method 2: Pictures
Create a pictorial representation of how a computer works. Again, do not be literal, but demonstrate an understanding of the processes and logic. You may not use pictures of actual computer components in your representation.
