What is Apex, Apex Classes, how to code in apex

Salesforce could be a driving client relationship administration (CRM) stage that permits businesses to oversee their client intuitive and streamline their deals forms. Whereas Salesforce gives a strong set of features and usefulness out-of-the-box, there are times after you may got to amplify its capabilities or customize it to meet your particular commerce needs. Usually where Summit, Salesforce’s effective programming dialect, comes into play.

Apex is a strongly-typed, object-oriented programming dialect that’s planned particularly for the Salesforce stage. It permits engineers to construct custom commerce rationale, mechanize complex workflows, and make integrations with outside frameworks. Pinnacle runs on the Salesforce servers, which implies it is executed in a secure and controlled environment.

Key Features of Apex:

Simple Integration:
Apex gives consistent integration with Salesforce objects and information, permitting Developers to connected with the multiple platform’s seamlessly. This empowers you to make custom forms, triggers, and workflows that automate business operations and ensure data integrity.

Effective Database Get to:

With Apex, you’ll be able effortlessly query, update, and control Salesforce records using using a familiar SQL-like syntax. This makes it simple to recover and alter information inside your applications, giving a steady and proficient way to connected with the fundamental database.

Customizable User Interface:
Apex permits you to construct custom client interfacing utilizing Visualforce or Lightning Web Components (LWC). This gives you the adaptability to form custom fitted encounters for your clients, upgrading the generally client involvement and expanding efficiency.

Robust Error Handling:

Apex provides robust error handling mechanisms, including try-catch blocks, to handle exceptions and ensure graceful error recovery. This allows you to build reliable and robust applications that can handle unexpected scenarios and provide meaningful error messages to users.


Apex has built-in support for unit testing, permitting Developers to type in test strategies to approve their code. This makes a difference guarantee that your code capacities as anticipated and minimizes the chance of presenting bugs or relapses.

Example: Creating a Custom Apex Class

Let`s dive into a simple example to demonstrate the power and flexibility of Apex. Suppose we have a requirement to calculate the average order amount for a set of opportunities in Salesforce. We can achieve this by creating a custom Apex class. Here’s how it can be done:

public class OpportunityHelper {
  public static Decimal calculateAverageOrderAmount(List<Opportunity> opportunities) {
        Decimal totalAmount = 0;
        for(Opportunity opp : opportunities) {
            totalAmount += opp.Amount;
        return totalAmount / opportunities.size();

In the above example, we define a custom Apex class called OpportunityHelper. It contains a single static method called calculateAverageOrderAmount, which takes a list of opportunities as input and returns the average order amount as a Decimal value.

Inside the method, we initialize a variable totalAmount to store the sum of all opportunity amounts. Then, we iterate over each opportunity in the list and add its amount to the totalAmount variable. Finally, we divide the totalAmount by the number of opportunities in the list to calculate the average.

This is just a basic example to illustrate the syntax and structure of an Apex class. In a real-world scenario, you would likely have more complex business logic and additional methods within your class.

Apex could be a effective programming dialect that empowers developers to expand the capabilities of Salesforce and make custom applications and solutions, custom fitted to particular necessities. With its simple integration, effective database get to, customizable client interface, strong mistake taking care of, and testability highlights, Apex gives a strong establishment for building adaptable and secure arrangements on the Salesforce stage.

Thank You! Cheers.
