Quartz scheduler:

Quartz is an open source job scheduling framework that can be integrated into a wide variety of Java applications.

Where to use quartz scheduler?

If our application have tasks to run on a predefine date and time then quartz scheduler is the ideal solution.

Features of quartz scheduler:

  1. Quartz can be integrated within another free standing application.
  2. Quartz can run as a stand-alone program.
  3. Quartz schedules the jobs to run when a given Trigger occurs.
  4. Quartz can begin and commit JTA transactions.

Quartz job:

Quartz job is used for the logic or code which you want to execute. It implements org.quartz.Job interface.

Quartz trigger:

Quartz trigger is used to define the moment when the quartz scheduler will execute quartz’s job.

Types of quartz trigger:

1. SimpleTrigger – SimpleTrigger setting start time, end time, repeat count and repeat interval for quartz’s job.

SimpleTrigger’s Constructors:

public SimpleTrigger(String name, String group, Date startTime, Date endTime, int repeatCount, long repeatInterval)

2. CronTrigger – CronTrigger uses cron expressions to specify the moment when to execute quartz’s job. A cron expression is made up of seven sub expressions:

  1. Seconds
  2. Minutes
  3. Hours
  4. Day-of-Month
  5. Month
  6. Day-of-Week
  7. Year (optional field)

3. Scheduler class – Scheduler class is used to connect the quartz job and quartz trigger together and execute the job.
