일본어 문장을 입력하고 [실행]하시면,
단어, 조사, 동사 등으로 분리하여 결과를 보여줍니다.

한자로 된 단어의 읽는 방법이나
동사의 기본형도 나오니 공부하는데 도움이 될까 싶어 올립니다.

Job - 이 인터페이스를 상속 받아서 execute 메소드를 구현해야 됩니다. (실행 수행되는 내용)
JobDetail - 
Trigger - 작업을 언제 실행할 지 정의합니다.
  SimpleTrigger - start time, end time, interval time, repeat times 등을 설정할 수 있습니다.
  CronTrigger - Linux의 cron 하고 비슷하게, 특정 시간이 되면 발동하게 해줍니다.
 
SchedulerFactory
  StdSchedulerFactory - 클래스패스에 quartz.properties 파일을 먹고 삽니다. 
    Scheduler - 스케쥴 팩토리에서 얻어 옵니다. JobDetail과 Trigger를 가지고 스케쥴을 정할 수 있습니다.

package QuartzApp;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

public class HelloJob implements Job {

 @Override
 public void execute(JobExecutionContext arg0) throws JobExecutionException {

     SchedulerFactory schedFact = new org.quartz.impl.StdSchedulerFactory();
     Scheduler sched = schedFact.getScheduler();
     sched.start();

     JobDetail jobDetail = new JobDetail("HelloJob", HelloJob.class);
     SimpleTrigger trigger = new SimpleTrigger("HelloJob");
     trigger.setRepeatInterval(1l);
     trigger.setRepeatCount(100);  // 100번 반복
     sched.scheduleJob(jobDetail, trigger);
   } catch (Exception e) {
