Operator Precedence in Java | Day 3 of 100daysofcode

by Casey Spaulding 03 Mar, 2023

Today was a deep dive into operator precedence in Java. It mostly follows the same rules as PEMDAS P- Parentheses, E- Exponents, M- Multiplication, D- Division, A- Addition, and S- Subtraction for order of operations.

Seems like a simple concept but it did get tricky for me once you start adding the modulus operator into a long equation such as 15 / 3 % 2 * (6+2) or 9 % 5 % 2 equals what?

So what I learned was that * takes precedence over the % operator and if you have several modulus operators next to each other it is left to right. Here is a good chart from Princeton.edu

Primitive Data Types | Day 2 of 100 days of code

by Casey Spaulding 03 Mar, 2023

written by Casey Spaulding

Today I learned about Java primitive data types, the java scanner class, and a little about reference types. Then I built a small console program to test each primitive data type in a real-life example. Also got to get used to Eclipse IDE for the Java world. Enjoying starting at the basics with Java. Very similar to C sharp thank goodness.

Starting again. Day 1 of .. @Skillstorm. .NET like JDK

by Casey Spaulding 02 Feb, 2023

written by Casey Spaulding

I say starting again because feels like I am starting over after getting so far learning .NET, completing the Coder Foundry self-paced boot camp, and doing the 100 days of code challenge which I think I am going to do again starting today.

I had my first day of the Java program at SkillStorm. It was an orientation day with some IDE setup and light programming. I have been self-teaching for a while now but focusing on .NET.

I learned about several things but will focus on what I learned about the differences between the JDK, JRE, and JVM. So the Java Development Kit includes all the development tools, the JRE is the java code library, and the JVM converts the Java code to native code the computer can read.

Here is the summary.

Java was made to “Write once, run anywhere
The JDK has everything you need to develop java applications
The JRE has everything you need to run Java apps.
The JVM is responsible for running the applications.

Maybe it’s just me but this reminds me of how C# and .NET are set up a kind of with the CLR? Seems to me that Java had the cross-platform idea a long time ago and no one has perfected it but .NET is trying. I need to do more research. Whoever is reading this please understand that I am still learning. What do you think?

Why Start A Blog?

I am not good at writing but I would like to be a good writer. I have heard that writing every day will help you become a better writer. Makes sense to me.
Blogging is a great way to document your journey.
While learning to code I will be forcing myself to write concise summaries of what I have learned and try to teach it to an imaginary reader. I have read that you learn more by teaching. So this will help with my learning process plus with an added bonus someone might read it someday.
Sounds fun.
Maybe it will build into something more. What? I don’t know but it would be cool to own a record of my journey and thoughts.

Art, Creativity and Code

Interesting how art, creativity and code overlap in many ways.

This is a good book if you have not read it. Here is one cool quote of many in this book.

Draw the art you want to see, start the business you want to run, play the music you want to hear, write the books you want to read, build the products you want to use – do the work you want to see done.
