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!
I’m working with a couple of different groups on various projects to learn and teach two related Object-Oriented Programming (OOP) languages: Apex and Java.
One of the big stumbling blocks for beginners is understanding OOP terminology and concepts. In this blog post, I’m taking the opportunity to gain better understanding of the terminology, by explaining it to you.
First let me say that I LOVE Salesforce and in addition, sometimes they don’t make it easy for a newbie to understand what the heck they’re talking about! This is the first sentence of the Salesforce ,What is Apex.
Apex is a strongly typed, object-oriented programming language that allows developers to execute flow and transaction control statements on the Force.com platform server in conjunction with calls to the Force.com API.
Last night I took my first steps on the path to becoming a code hero. I started with a book, Head First Java, recommended by one of my code heroes, David Liu from www.sfdc99.com.
