In Salesforce Apex, loops are among the most important concepts every developer must understand.
Loops help you execute a block of code multiple times based on a condition. This is very useful when working with multiple records in Salesforce, such as Accounts, Contacts, or Opportunities.
In real-time projects, developers often need to process large amounts of data. Instead of writing the same code again and again, loops allow us to automate repetitive tasks.
For example, if you want to update 1000 contact records, you can use a loop to process each record one by one efficiently. This makes your code cleaner, faster, and easier to maintain.
In Salesforce Apex, loops are very useful when you need to go through multiple records and apply some conditions. For example, a company wants to identify high-priority customers.
As a Salesforce developer, I write an Apex loop to go through all Account records. Within the loop, an if statement checks whether the customer’s total purchase amount exceeds $10,000.
In this article, I will explain how to use loops in Salesforce Apex. In this, we will understand how to declare and use them to implement complex business logic and automate processes.
