How do I use Quartz Scheduler for job scheduling in Java?

Quartz Scheduler is a powerful library for scheduling jobs in Java. You can start by adding the Quartz dependency to your project.

What are the basic components I need to set up?

You'll need a Job class that implements the Job interface, a Scheduler instance, and a Trigger to define when the job should run.

Can you give me a simple code example?

Sure! Here's a basic example:

public class MyJob implements Job {
    public void execute(JobExecutionContext context) {
        System.out.println("Job executed!");
    }
}

Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
JobDetail job = JobBuilder.newJob(MyJob.class).build();
Trigger trigger = TriggerBuilder.newTrigger().startNow().withSchedule(SimpleScheduleBuilder.repeatSecondlyForever(10)).build();
scheduler.scheduleJob(job, trigger);
scheduler.start();

How do I handle job persistence?

You can use a JobStore like JDBCJobStore to persist jobs in a database, ensuring they survive application restarts.
