cron expression parsing into java date

Question

• my database having 10 18 16 ? * SUN,MON,WED,FRI * cron expression then how to convert into Java date.
• how to comparing with present day time.

Answer 1

Please use:

import org.springframework.scheduling.support.CronSequenceGenerator;

final String cronExpression = "0 45 23 * * *";
final CronSequenceGenerator generator = new CronSequenceGenerator(cronExpression);
final Date nextExecutionDate = generator.next(new Date());

...and then I suggest use Joda DateTime for date comparison.
