How can I increment a date by one day in Java?

Question

I\'m working with a date in this format: yyyy-mm-dd.

How can I increment this date by one day?

Answer 1

In java 8 you can use java.time.LocalDate

LocalDate parsedDate = LocalDate.parse("2015-10-30"); //Parse date from String
LocalDate addedDate = parsedDate.plusDays(1);   //Add one to the day field

You can convert in into java.util.Date object as follows.

Date date = Date.from(addedDate.atStartOfDay(ZoneId.systemDefault()).toInstant());

You can formate LocalDate into a String as follows.

String str = addedDate.format(DateTimeFormatter.ofPattern("yyyy-MM-dd"));
