Today, I want to talk about the difference between statements and expressions in Computer Science and why ignoring that distinction has consequences.
Usually, I try not to write too many opinion pieces about code, but I felt like I should mention that it’s okay to test private methods.
As with many posts in this series, I’m interested in examining some of the pitfalls when learning to code. Today, we’ll cover the pitfalls when copying mutable data types.
As I continue to teach, I’m constantly introduced to new ways to code. For instance, one of my students just introduced me to `i = i++`. Care to guess how it works?
Forget endless if statements! It’s time to solve Rock Paper Scissors using modular arithmetic in Python.
Recently, I found out that the `else if` keyword doesn’t exist. To put it bluntly, you’re going to want to read this one.
As a teacher, I like to warn my students of the various pitfalls in computer science. Today, let’s talk about Java’s substring method.
Sometimes it’s fun to make an interactive application with Scanner. Unfortunately, we have to be careful with Scanner methods.
When learning Java for the first time, many students tend to struggle with the private and public keywords. Welcome to the world of access modifiers!
