If you say ‘yes’, then this article will help you feel it easy and enhance your passion and zeal towards Salesforce development. While it may be easy for the technical guys to learn it quickly, non-technical people need not worry anymore now on how to deal with learning Salesforce Apex code. Here are given the simple and best methods to get yourself excel in the leading-edge Salesforce development tool.
Before you go to find the various ways of Apex learning, here I have a simple, yet, brief note on what Apex is.
Apex – the main element of Salesforce development
Though Salesforce development includes no or minimal coding, it enables better executions and operations of Salesforce applications through advanced programming languages like Apex. Salesforce developers use Apex, an object-oriented programming language for managing the back-end database operation. They also use it to enable client-server interfaces for developing third-party applications. It is also used in dealing with calls to the API. Therefore, Apex is considered to have three basic tools – Builder (interface features for customized features), API and code.
One of the interesting features of Apex is that it enables business logic to various events – may it be recorded updates, button clicks, and Visualforce pages. Apex triggers and web service requests are the common means through which Apex code is initiated. It has its extensive role in Salesforce Classic as well as advanced Lightning Experience. Different editions like Enterprise, Performance, Developer, Unlimited, and Database.com enable Apex features. Apex is the best provision of integration; it is easy to use, reliable, multitenant-aware, and rigorous.
Here are some important and core Apex concepts –
- Variables and data types – dates, numbers, strings, and sObjects
- SOQL Queries
- Control Structures
- DML Operations
- Methods and Classes
- Dot notation – navigating relationships and using numbers
- Using loops – For, Do-while, and While loops
- Comparison Operators
- Data Collections – lists, maps, and sets
- Conditional statements – If and If-else statements
- Invoking a method
- Creating, updating, and deleting records
The coding terminologies and techniques of Apex are same as that of Java. Now that you have known it, let’s dive into the struggling means to learn Salesforce Apex code.
How to learn Salesforce Apex Code easily?
Grasping the knowledge on Apex code is not a big deal if you follow these simple approaches.
Revive with JAVA
As known, Apex code is similar to Java programming. So, once you are adept in JAVA skills, then you can swim greatly in the pool of Apex codes. Whether you are from IT or non-IT background, I recommend you to learn and be perfect in JAVA terminologies and coding. The Head First Java Book helps you to get into the basic track of learning Java. Simultaneously, you can also achieve hands-on experience on Java through working with some internship to hone your programming skills.
Upon grabbing Java techniques, you can avail a great help to get an easy understanding of Apex code. Furthermore, by learning Java, you can be easily capable of understanding the other element of Salesforce called Visualforce.
