This series of videos is suitable for programmers with minimal (or no) programming experience who want to learn Java. In this video, we will go over the arithmetic operators in Java. The way division works might surprise you! We'll cover the mod operator (%), and order of operations. We'll also use jshell in this video, a handy tool that comes with your Java installation that allows you to quickly evaluate small bits of Java code.

There is a suggested (free) book below that you could read along with the videos lessons. However, the video is very straightforward and can also stand alone or accompany any other introductory Java textbook. Let's have some fun learning to program in Java!
