How to add multiple triggers for a job in Quartz

In this example we will see how we can add multiple trigger for a single job in Quartz scheduler.
We will follow the following steps :

1.At first lets create a job class.

package com.techniqpatch.quartz

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
 
public class TestJob implements Job {
 
 @Override
 public void execute(JobExecutionContext context)
  throws JobExecutionException {
  System.out.println("Job is runing");
 }
 
}

2.Now lets create a class that will schedule the TestJob with two trigger

package com.techniqpatch.quartz;

import java.text.ParseException;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.quartz.CronScheduleBuilder;
import org.quartz.CronTrigger;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.JobKey;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.quartz.impl.StdSchedulerFactory;

public class QuartzTest {
 Scheduler scheduler;

 public void schedule(String[] args) throws ParseException,
   SchedulerException {
  SchedulerFactory factory = new StdSchedulerFactory();

  scheduler = factory.getScheduler();
  Map<JobDetail, List<Trigger>> triggersAndJobs = new HashMap<JobDetail, List<Trigger>>();
  List triggerList = new ArrayList();
  String groupName = "GroupName";
  String jobName = "JobName";
  JobKey jobKey = new JobKey(jobName, groupName);
  String triggerName = jobName;
  List createdTrigger = new ArrayList();
  createdTrigger.add("02 01 02 1 * * ?");
  createdTrigger.add("02 01 03 5 * * ?");

  JobDetail job = JobBuilder.newJob(TestJob.class)
  .withIdentity(jobKey).usingJobData("groupName", groupName)
  .usingJobData("jobName", jobName).build();

  CronTrigger trigger;
  CronTrigger trigger1;

  trigger = (CronTrigger) TriggerBuilder
   .newTrigger()
   .withIdentity(triggerName + "0", groupName)
   .withSchedule(
    CronScheduleBuilder.cronSchedule(createdTrigger.get(0)))
   .build();

  trigger1 = (CronTrigger) TriggerBuilder
   .newTrigger()
   .withIdentity(triggerName + "1", groupName)
   .withSchedule(
   CronScheduleBuilder.cronSchedule(createdTrigger.get(1)))
   .build();
  triggerList.add(trigger);
  triggerList.add(trigger1);

  triggersAndJobs.put(job, triggerList);
  if (!scheduler.isStarted()) {
   scheduler.start();
  }
  scheduler.scheduleJobs(triggersAndJobs, true);

 }
}

After running the program, you will see that the job is executed in different intervals by the above two trigger.
