Understanding Apex Classes and Objects in Simple Terms

In the world of programming, classes and objects are like blueprints and the things built from those blueprints. Apex, Salesforce’s programming language, also uses classes and objects to create custom functionality.

Let’s break down what they are in simpler terms.

Apex Classes – The Blueprints

Imagine you want to build a house. Before you start building, you need a plan, a blueprint that outlines how the house should look and function. In Apex, a class is like that blueprint. It defines what an object (in this case, a custom piece of code) should contain and how it should behave.

For example, if you’re building a class for a ‘Person,’ it might specify that a person has a name, age, and address, and can perform actions like walking or talking. You create this class to reuse it later, just like you can use the same blueprint to build multiple houses.

Here’s a simple representation of an Apex class for a ‘Person’:

public class Person {
    public String name;
    public Integer age;

    public void walk() {
        // Code for walking goes here
    }

    public void talk() {
        // Code for talking goes here
    }
}

Apex Objects – The Things Built

Now, think of objects as the actual houses built from those blueprints (classes). When you create an object in Apex, you’re making a specific instance of a class. It’s like constructing a real house based on the architectural plan.

If you want to represent a particular person, you create an object from the ‘Person’ class blueprint. This object has its own unique values for properties like name and age and can perform actions defined in the class.

Here’s how you can create an object from the ‘Person’ class:

Person john = new Person();
john.name = 'John';
john.age = 30;

In this code, john is an object of the ‘Person’ class with its own name and age. You can create more ‘Person’ objects, each with its characteristics.

In summary, Apex classes are like blueprints that define what an object should contain and do. Objects are instances of those classes, representing real data and actions. By using classes and objects effectively, you can create organized, reusable, and customized code in Salesforce to meet your specific needs. As you dive deeper into Apex, you’ll discover how to create complex systems by designing and using classes and objects wisely.
