Syntax

To schedule an Apex class to run at specific times in Salesforce, follow these steps:

Implement the Schedulable Interface: First, create an Apex class that implements the Schedulable interface. The Schedulable interface contains a single method called execute, which you must implement. Here’s the basic syntax:

public class MyScheduledClass implements Schedulable { public void execute(SchedulableContext sc) { // Your code here } }

Schedule the Class: To schedule your class, use the System.schedule method. It accepts three parameters:

1. Job name (a descriptive name for your scheduled job)

2. Cron expression (specifies when the job should run)

3. An instance of your Schedulable class

Example:

MyScheduledClass myJob = new MyScheduledClass(); String cronExpression = '0 0 13 ?'; // Runs every day at 1:00 PM String jobId = System.schedule('My Scheduled Job', cronExpression, myJob);

The System.schedule method schedules the job with the specified cron expression.
