Increment the date in Java by 1-day

Question

I want to increase the date in Java by 1. Can we do that?If Yes what is the simplest way to do that?

Answer 1

You can try this way

SimpleDateFormat simpleDateFormat1 = n`ew SimpleDateFormat("yyyy-MM-dd");
Calendar calendar = Calendar.getInstance();
calendar.set(1970,Calendar.NOVEMBER,31);
System.out.println(simpleDateFormat1.format(calendar.getTime()));
calendar.add(Calendar.DATE, 1);
System.out.println(simpleDateFormat1.format(calendar.getTime()));
calendar.add(Calendar.DATE, -1);
System.out.println(simpleDateFormat1.format(calendar.getTime()));

Will Print:

1970-11-31
1971-12-01
1970-11-31

public class DateUtil
{
    public static Date addDays(Date date, int days)
    {
        Calendar cal = Calendar.getInstance();
        cal.setTime(date);
        cal.add(Calendar.DATE, days); //minus number would decrement the days
        return cal.getTime();
    }
}

public class DateUtil
{
    public static Date addDays(Date date, int days)
    {
        Calendar cal = Calendar.getInstance();
        cal.setTime(date);
        cal.add(Calendar.DATE, days); //minus number would decrement the days
        return cal.getTime();
    }
}
