GUI Programming
Hi folks. Please continue working through the notes and challenge problems from earlier this week.
For those who are finishing up or are ready to move on, take a look at this next topic: creating graphical user interfaces in Java.

Continue ArrayList Notes
Hi all, please continue to work through the material posted yesterday.
Quick correction: Where it says ArrayIndexOutOfBoundsError in the notes, it should have said ArrayIndexOutOfBoundsException.
Feel free to send me an email if you have any questions. Thanks!

Exploring Data Structures
Hi everyone! I hope you have enjoyed your break. I will be returning next Monday and I look forward to seeing you all then.
For this week, we will learn how to create a useful data structure called an ArrayList. It can hold a collection of items like a normal array, but can also change its size as needed.
I have prepared a series of guided notes for this topic. Please follow along with these notes with BlueJ open to a new project called DataStructures. Whenever you see a section of Java code, please add this code to your project.
- Data Structures Introduction
This first slideshow does not have any Java code to add to your project. (Press spacebar to go to the next slide or use the up, down, left, and right arrows to navigate).
- Building an ArrayList from Scratch
This second slideshow has many sections of code to follow along with. Please create a class called DynamicArray in your BlueJ project and follow along as you read the slides.
- Using ArrayList Methods
This last section of notes has some code examples and then challenge problems for you to complete at the end.

Implications of the Halting Problem
So far we have seen that there is a Turing Machine (a Universal Turing Machine) that can simulate the operations of other Turing Machines. And Turing used this idea to give a surprising proof that there are some things that computers cannot do.
A Turing Machine (or computer) cannot decide if another Turing Machine (or computer program) will run forever on its given input or eventually halt.
This result stands for all times. Even if we are able to make computer hardware with as-yet unimaginable technology, this limit of computation will never be overcome.
For today's lesson, please read this description of more implications of the Halting Problem's undecidability.
Thursday, March 2, 2023
The Universal Turing Machine
Hi everyone. I forgot to present this lesson to you first, which is background knowledge to make more sense of the halting problem, which you learned about yesterday.
Today's readings establish a way for one Turing Machine to interpret another Turing Machine's instructions. As you will see, it is possible to build a "Universal" Turing Machine that can be reprogrammed with the "blueprint" of another Turing Machine. Most Turing Machines can perform only a very specific task, but the Universal Turing Machine can do anything that any Turing Machine can do. In that sense it is like a general computer.
The videos that you watched for homework rely on this idea—that one Turing Machine can simulate another one.
I find this idea extremely fascinating, and I hope that you will too!
Please read the following:
There is no homework today. Thank you.

The Halting Problem
Please read the following online lessons closely and make an attempt to answer the questions for yourself before moving on.
The two lessons for the day are to introduce "The Halting Problem" before we later set up Turing's ingenious proof of it's inability to be solved with Turing Machines.
The videos for lesson two are not included for today's in-class lesson. Please view them at home for homework:
- Turing & the Halting Problem - Computerphile
- Proof that Computers can't do Everything (The Halting Problem)

Yay! I'm a dad!
Hi class, as you might have heard by now, my baby arrived a little sooner than expected! Her name is Aletta Ruth Haney Kanim. She is named after important people in our families and is getting a doubled last name. We're calling her Allie.
Allie is in perfect health and so is Ms. Kanim. I feel amazingly blessed by that.
I will return to class the second week of quarter 4 on Monday. In the meantime, I will leave some assignments posted on the website for you guys to complete independently while you have a sub.
Here's a picture of me holding her on her birthday:
Thanks guys!
Finish up the Designing Turing Machines problem set
We have one day left to finish the Turing Machines problem set. Please have this ready to turn in by tomorrow morning. I will ask the sub to collect them and place them on my desk in the faculty office.
Please complete it for homework if you run out of time today. If you are already done, you may use this period as a study hall. Thank you!

Advent of Code
Join people around the world in celebrating the holidays with fun programming challenges: Advent of Code.
Each day until Christmas, two new puzzles unlock in this advent calendar. They get progressively harder each day, but they are a good opportunity to practice using some of the skills we have been learning recently like iteration, arrays, and file io.

Iteration Strategies Handout
Arrays Mixed Practice
We began working in groups on this problem set to practice processing arrays using the iteration strategies.
Wednesday, November 2, 2022
Arrays and Computer Memory
The limitations of arrays make sense when we understand how they are backed by the memory of our computer. Take a look at the slides from today and the code examples that we created together.

Arrays Introduction
Today we introduced arrays in Java. You can find the slides and exercises below.

Sub Plans:
Sorry I can't make it in today folks. I'm not feeling very well :(
Please work on the following activities while I am out. They will help you prepare for the quiz tomorrow and for our next unit in programming: arrays.
Logic Problem Set
Answer the following questions in your notebook to review for the Conjunctions Quiz.
Translate the following sentences into logical symbols:
- "All animals are equal, but some animals are more equal than others." - Animal Farm by George Orwell
- "Nowadays people know the price of everything and the value of nothing." - The Picture Of Dorian Gray by Oscar Wilde
- "If we respected only what is inevitable and has a right to be, music and poetry would resound along the streets." - Walden by Henry David Thoreau
- "To produce a mighty book, you must choose a mighty theme. No great and enduring volume can ever be written on the flea, though many there be who have tried it." - Moby Dick by Herman Melville
Prove the following:
- Premises: (P -> Q) ^ (R -> S), -Q ^ -S. Conclusion: -P ^ -R.
- Premises: P ^ ((-Q -> R) ^ (Q -> -P)). Conclusion: R.
Programming Research Task:
Search for the following information online. (Websites only. No videos, please).
Feel free to try out any code you find in BlueJ on the code pad.
- What is an array used for in Java?
- How do you make an array of integers that holds the values 2, 4, 6, 8, and 10?
- How do you make an array of Strings that holds the values "moo", "quack", and "meow"?
- How do you see a single value in an array by its index?
- What number index is "moo" in your String array? What number index is "meow"?
- How do you change what is in an array at a particular slot? Change "quack" to "oink".
- How do you create an empty array of doubles that has space for 500 numbers?
- What is the best way to print an array? What happens when you do the obvious: System.out.println(animalNoiseArray);
Silent Study Hall
When you are finished, please work on something else quietly for the rest of the period. Maybe your Senior Thesis?

Object Examples
We created classes that modelled real-world things. This was our first introduction to object-oriented programming.
In this style of programming, related data is bundled together in an object defined from a class. Over the course of the program, the data changes (mutates) through its methods.
Example 1: Radio
Radio class:
Example 2: Mover object
