CodingBat: 15 questions from the AP-1 set.

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-

Picture Lab QuickCode: Write two unrelated methods for the Picture class. Full value if complete by 7:45.

Picture Lab 1

Copy the Picture Lab folder from the common drive

Complete parts A1 through A7 of the Picture Lab from the Student Guide

Review the questions at the end of each part

Inheritance 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. The Right Triangle should create an Isosceles Right Triangle.

 

Provide an appropriate constructor for each of the classes and have 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 end of period.

Design and implement a class called MonetaryCoin that is derived from the Coin class from Chapter 4. Create an instance data variable in the MonetaryCoin that stores its value and add a method that returns ts value. Create a main driver class to instantiate ten coins. Flip each coin, print the value and face of the coin and then print the sum of the coins that show heads. Do not replicate any data or methods from the Coin class in the MonetaryCoin class.

ArrayList Quickcode- Using the files in the ArraylistQC folder in the common drive, complete the employeeIsEligible() and processRetirements() methods of the Company class. Copy the entire folder to your G drive folder. Period 1: Full value if completed by end of class.

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.

Party Class - Final Version

 

Extend the Party Class version 3 to overload your add and remove guest methods so that they will take an ArrayList of Guests as a parameter. The add method should only add the guests if they all meet the requirements for entry. The remove method should remove all of the guests and adjust the appropriate Party instance data.

 

Modify the toString method, if you have written one, so that it prints the number of male and female guests at the party.

 

Modify the driver class so that the new features are tested.

Reimiplement the Party 2 application using an ArrayList to store the guests. If you have not done so yet, create a Guest class that stores the name, gender, and age of the guest as instance data. Typecast the ArrayList to hold Guest objects.

 

issues of saving in an open space are handled automatically, but how will you handle maximum party size?

(Textbook section 6.7)

Students should be able to create an ArrayList and use the add, set, get, remove, and size methods.

Party class version 1

Create a class called Party that will track the names of the current guests of a party. The Party will have a fixed maximum number of guests. The Party class should be able to add guests (if there is room), remove guests, report the number of guests at the party, and check to see if a guest is present at the party.

 

Create a main method in a separate driver class to test the functions of the Party class.

 

Design Questions to consider:

What data type will be used to store the name of a guest?

What data type will be used to store the list of guests?

What other instance data might be needed?

How many constructors do you need?

What are the return types and parameters for each method?

Party class version 2

Modify the Party class from version 1 to add the following:

• Each guest should have gender and age information.
• The party should have maximum and minimum ages and only allow guests within that age group.
• The maximum number of guests must be an even number
• The number of Male guests and the number of Female guests must be within 3 of each other. If the difference is greater than 3, no additional guests can be added that will increase the difference.

Create a driver class to test the new functions of the Party class.

Design Questions to consider:

• What data type will be used to store the name of a guest?
• What data type will be used to store the list of guests?
• What other instance data might be needed?
• How many constructors do you need?
• What are the return types and parameters for each method?

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. We have not covered ArrayLists yet, so they will not be included on the final exam.

Part 1: Get your decade assignment from the attached file. Use the link above and review the 10 years of your decade. Identify 5 themes that are prominent in the development of computers during your decade. In a Google Doc, list your themes and give at least 3 examples. At least one example should be from a source other than the listed website. Post the document to the Google Classroom Assignment.

 

Part 2: Form a group with 3 other students from the same decade assignment. Share your findings. As a group, create a poster that outlines the major themes from the decade. The poster should use text and images.

 

Part 3: Present your poster to the class on November 13

Quiz: Recursion and Binary

 

Concepts on this quiz:

 

Make a copy of Magpie3 called MagpieFinal and add the following functionality:

 

1. Change the greeting so that Magpie asks for the users name and then stores the name in a variable. The name should then be used randomly in the responses.

 

2. Add code to respond to the phrase "Tell me about..."  Choose two topics with at least two keywords for each topic. Have three responses for each topic. Each time that the user asks about the topic using any associated keyword, it will give a different response. When it runs out of responses for that topic, it should respond "I don't know any more about " with the name of the topic. If the Tell me about phrase is not one of the topics, it should respond "I don't know anything about" with the topic.

 

Make a copy of MagpieRunner3 called MagpieRunnerFinal. Modify it as necessary to make MagpieFinal work.

Complete at least 10 problems from each of the following sets:

Inside the Computer Project: Describe how a computer works in two different ways. Post your descriptions in Google Classroom

Method 1: Words
Write a description of how a computer works. Do not 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.
