Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Control Flow Statements

Apex provides if-else statements, switch statements, and loops to control the flow of code execution. Statements are generally executed line by line, in the order they appear. With control flow statements, you can make Apex code execute based on a certain condition, or have a block of code execute repeatedly.
