cronexpression 을 작성하고 이제 맞는지 테스트 하기~

String expression = "0 0 2-4/2 * * ?";
CronExpression cronExpression = new CronExpression(expression);

Date nextExecuteDate1 = cronExpression.getNextValidTimeAfter(new Date());
Date nextExecuteDate2 = cronExpression.getNextValidTimeAfter(nextExecuteDate1);

System.out.println(nextExecuteDate1);
System.out.println(nextExecuteDate2);
