In my last blog post, I wrote about variables, and in particular, primitives. Today I’m going to expand on variables and talk about the oh-so-powerful idea of “collections.”
Unlike Java, which only has one type of collection (Arrays, also know as a Lists), Apex has three to choose from: Lists, Sets, and Maps. Together, we’ll go into each of these types of collections and show you what they are best used for, and how to use them when you start coding.
Thinking about variables makes me hungry. That might be taking things a little far, but I’ve been preoccupied with cooking and coding recently, so they seem to be merging in my mind. I think this stuff can be fun, and for me, silly analogies make it all easier to understand. Hopefully by the end of this post you’ll agree!
