Effective Lessons to become an expert on Salesforce Apex

Ever wondered why businesses subscribe heavily to Salesforce? It is not rocket science. Salesforce continues to be a one-stop platform to design custom solutions. Companies and corporate institutions alike benefit from the platform. This is why Salesforce professionals are high-priced assets, especially Salesforce Developers. But then, becoming a Salesforce Platform Developer 1 Certification is not a day’s job, given the need to master Apex programming. It takes time and skills to stand out. Let’s quickly run down the basics about APEX. It won’t get technical; that’s a promise!

About Apex Programming

Apex, a strongly-typed and object-oriented programming language, is the brainchild of Salesforce. Here, developers can easily execute the flow and transaction control statements on the Force.com server. Apex does this in harmony with calls to the Force.com API.

It is quite easy to test-run codes in Apex. What you need to do is to execute unit test cases. This exposes the areas that need to be improved in your codes. Besides, Apex is available in every series of Salesforce software. Such editions include Performance, Enterprise Developer, Unlimited, and Database.com.

Of course, Apex shares similarities with Java, including their syntax. However, unlike Java, Apex is case-insensitive. To save you time and energy, Apex updates automatically together with new releases from Salesforce.

You should bear in mind that Apex is not meant to be used in all cases. It is advisable to code in Apex only when the functions on the Salesforce platform are inadequate to solve complex business issues. You may check out other features of Apex here.

What You Should Know about Apex Environments

Code development is made easier with Salesforce Developer and Sandbox environments. Of course, you wouldn’t want a code full of errors. This is where the Sandbox environment comes in. Whether it is Developer Sandbox, Developer Pro Sandbox, Partial Data Sandbox or Full Sandbox, you can be sure to develop codes that match your needs.

Salesforce provides you with unique tools for efficient programming. You may develop your codes using these tools:

• Force.com Developer Console
• Force.com IDE
• Code Editor in the Salesforce User Interface

The Developer Console is a complete tool in the Salesforce environment. It allows the user to write codes, test codes, debug, and perform color-coding and auto-complete functions.

Developing Apex Codes with the Developer Environment

We lay emphasis here on objects and fields creation. These elements in Salesforce may be likened to the foundation required for the development of efficient codes. Follow this link to check the step-by-step process required in creating your objects and fields.

Get to Know the Types of Data in Apex

Remember we said earlier that Apex is strongly typed? This feature makes it vital that variables in Apex are declared with the specific data type. Before you start coding in the Salesforce environment, Apex variables are usually programmed to null. Hence, you must ensure to assign the proper values to the variables.

But not every data can work with Apex. So, let’s examine the data types supported by Apex:

1. Primitive Collections: This category of Apex data includes Integer, Double, Long, Date, DateTime, String, ID, Blob, and Boolean.
   The Boolean is used to determine falsity or truth in Apex. It is either true or null. “Date,” as the name implies, stores only dates. If you want to save time and date, then you should use the DateTime data.
2. sObject: sObject is a unique type of data in Apex. It serves as a table of data, just like in SQL. Such data may be standard or custom.
3. Enums: Enum is abstract data. It is simply unique among other types of data. Enum also allows variables to be predefined constants.

Other data types in Apex are given attention here.

What are Apex Variables?

This is a tripod stand of data type, identifier, and an optional Initializer. Variables perform one major role in Apex. They are the chambers that hold value.
