CST 338 - Week 7/8

 Take a look back at Homework 1: Histogram

After reviewing my work on this assignment, I don’t think there is much I would change about my process. Creating the display was the most challenging part, but I was reading Java documentation and watching videos and came across the LinkedHashSets, which made the process significantly easier. One change I might consider is using a single for loop in my bubble sorting algorithm. A teammate suggested this could be achieved by using a boolean to check if the array is sorted. Additionally, the only other change I would make is using the .repeat method to print a string of characters a set number of times, rather than having a long print message.

Highlight some of your victories

I came into this class with only surface-level knowledge of Java and no experience with Android development. Overall, I now feel fairly comfortable working in both areas, though I still need to look things up pretty often. One area where I've noticed improvement is in understanding the basics of Java. Additionally, although it might seem basic, I've also improved my understanding of HashMaps. Initially, I found them confusing and often mixed up keys and values, so I had to frequently check the documentation and explore the methods available.

CST 338 - Week 5

This week, we worked on a Markov Text Generator, which creates new sentences from a list of random words taken from a text file. After completing the homework assignment, we were tasked with reviewing each of our teammates' code for the Markov assignment.

Who did you work with?

My teammates Alan and Abdul.

What was your strategy for solving the Markov assignment?

I began the assignment by creating a skeleton for the class and then read the prompt for each method to think about how I wanted to work through it. I then implemented each method one at a time, not moving forward until the tests for each method passed. I did run into an issue trying to pass the addBadLineTest(), but that was due to me only accounting for the extra whitespace at the beginning and end of each line.

What was their strategy for solving the Markov assignment?

Abdul: "I started by making sure I understood what the assignment was asking for and what the goal was. Instead of writing the code, I took some time to think through the structure and logic. This helped me get a clear understanding of how to combine the statements and methods for completing the assignment." 

Alan: "I started by creating a skeleton of the Markov class, including all of the fields and methods in the assignment description. I then implemented all of the methods for creating the dictionary of words, and then later implemented all of the methods for generating sentences. Lastly, I worked through the two failing tests one at a time to fix the handful of bugs/missing features that they found."

How would you change your strategy having worked on the assignment?

I don't think I would change anything about my strategy process for writing the code. However, I did notice two of my teammates using a BufferedReader instead of a Scanner like I did. I am curious if that might be more efficient for completing this assignment, especially if we had a larger file to read from.


According to your classmate(s): how well does your code follow the Google Java Style Guide

Abdul: "Method names are clear and follow camelCase conventions. The code is clean, well-indented, and uses braces properly, aligning with style guide standards. Its logical flow is straightforward, making the code easy to read and maintain."

Alan: "The only thing that I could find is that the style guide asks for a blank line between the paragraph and the tags for javadoc ( §7.1.2)."

CST 338 - Week 4

This week we got together with teammates and reviewed each other's code for project 1.

You can work with up to three people (you MUST work with at least one other person)
1. With whom did you work?

I worked with Alan and Abdul.

What was your strategy for solving the assignments?
Did you start writing code right away? Did you plan it out on paper?

For the first 3 parts of the project, I didn't plan anything out, I read the prompt and took it one piece at a time, never moving on until I finished the first part. For the final part of the project, I just wrote everything and then dealt with the errors and bugs later. 

What was THEIR strategy for solving the assignments?

I would say me and Abdul took a similar approach and took it one step at a time, and Alan opted to write a skeleton for each class and then work on implementing it.

How would you change your strategy after having worked on the assignment?

Honestly, I don't know. I had a lot of trouble with the Library.java class, but the others went smoothly. So, I don't think I would change much. I did mess up writing another class by not paying close enough attention to the prompt, so I guess I will pay closer attention in the future.

According to your classmates, how well does your code follow the Google Java Style Guide?

There were a few issues with my code such as using 4 spaces for indentation, a column limit of 100, line-wrapping, and braces for if statements even when it's a single line.

We also learned we can automate some of the Java style guides in Intellji https://medium.com/swlh/configuring-google-style-guide-for-java-for-intellij-c727af4ef248.

 I never used JetBrains before this class, but I love them now!

CST 338 - Week 3

Feedback received about my Histogram Java code

Abdul brought to my attention that I can use append("=".repeat(29)) instead of creating a long string of equal signs. He noted my variable names, comments, and formatting were all good.

Alan mentioned that I could implement the bubble sort algorithm with a single loop by utilizing a boolean that tracks whether we changed the list on the previous pass. He also mentioned that my imports should be replaced with individual imports for each utility to increase readability and compilation time.

Farooqkhan mentioned he had no issues with my code's logic, formatting, variable names, or comments.

Identify any trends you noticed when evaluating the code of others

After viewing everyone's code, and reflecting on my own, I would say the thing it seemed everyone struggled with was creating the display and getting it to work according to the assignment specifications.

Was any part of the code a struggle for YOU?

Yes, I found the display to be difficult to display properly. It took me hours and trying a bunch of different things before I managed to get it to work.

Was any part of writing the code easy for YOU?

The sorting algorithm was not particularly difficult. I had never used a bubble sort algorithm prior, so I had to research it, but I found it easy to implement and understand.

What is your biggest victory?

My biggest accomplishment was completing the assignment on time and having my display work correctly.

CST 338 - Week 2

This week we worked on parts 1 (Book.java) and 2 (Reader.java) for our first project in the class which stores, manipulates, and analyzes information stored within a library. I didn't really have any issues, except for not realizing there was an enum class I needed to use. We will finish up Project 1 in the coming weeks by completing Shelf.java, and Library.java.

We also had to complete our first heavy homework assignment, Histogram, which reads a text file from a user and displays a histogram from the occurrences of characters in the file.

I never really ran into issues passing the unit tests, but I spent too long trying to implement a solution for taking the numbers from counting the letters, removing all duplicate numbers, and then printing them in descending order, so instead of 1 2 3 4 4, it printed out 4 3 2 1. I imagine I was overcomplicating the solution and there was a much simpler way to go about it. 

After trying a few different solutions and still having trouble, I thought I would use a HashMap to store the unique numbers as keys and then return those unique keys. However, I still encountered issues. While working to figure out what was wrong with my HashMap, I learned about LinkedHashSets and how they don't include repeating elements, and return the output in the same order it receives the input. This solution ultimately worked for me, but again, I feel I was overthinking the problem, and there was probably an easier way.

Going forward, I will try and spend a little more time thinking of possible ways to solve the problem and why my current approach is not working, instead of getting frustrated and constantly going through numerous methods to solve the problem.

CST 338 - Week 1

Discuss the process of solving the Coding Bat challenges.

(1) What were the steps you took to solve some of these challenges?

My initial steps to solving the problems involved reading the problem a couple of times and thinking through how I would approach the first step, such as iterating through a string using a for loop. I found myself struggling with some of the problems, spending over an hour on a couple of them. I should have come back to it later instead of overthinking my solution. When I struggled, I tried to reference the Java help sections on the Codingbat website and rewatched the videos.

(2) Did you plan it out or throw code at it?

Generally, when working on the problems, I plan my approach and write comments on what I need to accomplish for each line or comment on my thought process to stay on track and explain why that solution works. There were a few times when I was tired and frustrated, and I just kept trying different ideas until the code ran. Occasionally, if my shorter solution wouldn't work, I would essentially "brute force" my solution with more lines of code than likely needed.


(3) What worked?

I found that using the basic concepts explained in the respective sections on the Codingbat website was all I needed to solve the problems. I often went to using "for loops" and "if statements" for many of the problems.

(4) What DID NOT work?

I tried using the ternary operator multiple times for a few problems, but I could not get it to pass all the tests. I would pass every test except for one or two, so I decided to default to if statements. These were some of the problems I spent way too long trying to complete.

(5) How many tries did it take?

For the easiest problems, I usually needed 1-4 tries, often because I forgot semicolons or misspelled something. For the tougher problems, it took anywhere from 10 to 20 tries, and I spent at least an hour on a couple of them. Later, I discovered various methods on the Oracle website that would have made some of the problems shorter, such as the .endsWith and .startsWith methods.

Intended for Professionals - https://www.youtube.com/watch?v=D4_qJ8CB5iY

This class has gone by faster than I expected. Throughout the course, I have learned a lot, but I would say the most significant things I learned were managing my time better, and effectively collaborating in a group environment. Previously, I had also only used MLA format in writing, and in this course, I learned how to write and cite sources using APA.

Our team frequently communicated through Google Chat to send assignment reminders and clarify things we discussed before or after our Saturday team meetings.

Overall, I think we did a good job collaborating, and I would attribute that to our communication and the constructive feedback we gave each other. In the future, I believe maintaining communication is the most important part of success, and we could improve on it even more.
