• Define a Job

  Create a class that implements Job interface:

  package com.example;
  
  import org.quartz.Job;
  import org.quartz.JobDataMap;
  import org.quartz.JobExecutionContext;
  import org.quartz.JobExecutionException;
  
  public class SimpleJob implements Job {
      @Override
      public void execute(JobExecutionContext context) throws JobExecutionException {
          System.out.println("SimpleJob is executed at: " + new java.util.Date());
  
          JobDataMap dataMap = context.getJobDetail().getJobDataMap();
          String jobParam = dataMap.getString("jobParam");
          if(jobParam != null) {
              System.out.println("Job parameter: " + jobParam);
          }
      }
  }

• Schedule the job

  package com.example;
  
  import org.quartz.*;
  import org.quartz.impl.StdSchedulerFactory;
  
  public class QuartzDemo {
      public static void main(String[] args) {
          try {
              Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
  
              JobDetail job = JobBuilder.newJob(SimpleJob.class)
                      .withIdentity("job1", "group1")
                      .usingJobData("jobParam", "Hello, Quartz!")
                      .build();
  
              Trigger trigger = TriggerBuilder.newTrigger()
                      .withIdentity("trigger1", "group1")
                      .startNow()
                      .withSchedule(SimpleScheduleBuilder.simpleSchedule()
                              .withIntervalInSeconds(5)
                              .repeatForever())
                      .build();
  
              scheduler.scheduleJob(job, trigger);
  
              scheduler.start();
  
              while (true) {
                  Thread.sleep(1000);
              }
  
          } catch (SchedulerException | InterruptedException e) {
              e.printStackTrace();
          }
      }
  }
