Java's Ternary Operator - No, it's Not!

I need to stop referring to the ternary operator (? :) in Java as “the ternary operator”. It is not the ternary operator; it is a ternary operator. It may currently be the only ternary operator in the core Java Language Specification - but even so, I should call it by its correct name, which is the conditional operator.

At least I am not alone.

Java's Modulo Operator - No, it's Not!

I need to stop referring to the modulo (%) operator in Java as “the modulo operator”. It’s the remainder operator.

Java does not have a modulo operator.

Here is how Java’s remainder operator behaves, along with division (assuming int):

Expression Result
5/3 1
5%3 2
5/(-3) -1
5%(-3) 2
(-5)/3 -1
(-5)%3 -2
(-5)/(-3) 1
(-5)%(-3) -2

Perhaps even more importantly, I need to understand that modulo operators in other languages may not always work in a consistent way when it comes to how negative numbers are handled. Here is a great article about that:

A table of results from the above article:
