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 simple way to do is:

Date.from(Instant.now().plusSeconds(SECONDS_PER_DAY))

Answer 2

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"));

Answer 3

You can use this package from "org.apache.commons.lang3.time":

 SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
 Date myNewDate = DateUtils.addDays(myDate, 4);
 Date yesterday = DateUtils.addDays(myDate, -1);
 String formatedDate = sdf.format(myNewDate);  

Answer 4

SimpleDateFormat dateFormat = new SimpleDateFormat( "yyyy-MM-dd" );
Calendar cal = Calendar.getInstance();
cal.setTime( dateFormat.parse( inputString ) );
cal.add( Calendar.DATE, 1 );
