How to add one day to a date? [duplicate]

Answer 1

This will increase any date by exactly one

String untildate="2011-10-08";//can take any date in current format    
SimpleDateFormat dateFormat = new SimpleDateFormat( "yyyy-MM-dd" );   
Calendar cal = Calendar.getInstance();    
cal.setTime( dateFormat.parse(untildate));    
cal.add( Calendar.DATE, 1 );    
String convertedDate=dateFormat.format(cal.getTime());    
System.out.println("Date increase by one.."+convertedDate);

Answer 2

I prefer joda for date and time arithmetics because it is much better readable:

Date tomorrow = now().plusDays(1).toDate();

Or

endOfDay(now().plus(days(1))).toDate()
startOfDay(now().plus(days(1))).toDate()

Answer 3

you want after days find date this code try..

public Date getToDateAfterDays(Integer day) {
        Date nowdate = new Date();
        Calendar cal = Calendar.getInstance();
        cal.setTime(nowdate);
        cal.add(Calendar.DATE, day);
        return cal.getTime();
    }

Answer 4

Java 8 LocalDate API

LocalDate.now().plusDays(1L);

Answer 5

Java 1.8 version has nice update for data time API.

Here is snippet of code:

    LocalDate lastAprilDay = LocalDate.of(2014, Month.APRIL, 30);
    System.out.println("last april day: " + lastAprilDay);
    LocalDate firstMay = lastAprilDay.plusDays(1);
    System.out.println("should be first may day: " + firstMay);
    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd");
    String formatDate = formatter.format(firstMay);
    System.out.println("formatted date: " + formatDate);

Output:

last april day: 2014-04-30
should be first may day: 2014-05-01
formatted date: 01

For more info see Java documentations to this classes:

• LocalDate
• DateTimeFormatter

Answer 6

I will show you how we can do it in Java 8. Here you go:

public class DemoDate {
    public static void main(String[] args) {
        LocalDate today = LocalDate.now();
        System.out.println("Current date: " + today);

        //add 1 day to the current date
        LocalDate date1Day = today.plus(1, ChronoUnit.DAYS);
        System.out.println("Date After 1 day : " + date1Day);
    }
}

The output:

Current date: 2016-08-15
Date After 1 day : 2016-08-16
