Finding date diff

Question

Hi friends,
I'm having doubt in time diff. Just assume this scenario.
Today is sunday and 13 hrs. I just want to know the difference between this and coming wednesday 01 hrs. But i don't know the date for coming wednesday. Is there any function available which returns the date for this coming wednesday. And i don't want to add 3 to the DAY_OF_MONTH part.

Answer 1

Today is sunday and 13 hrs. I just want to know the
difference between this and coming wednesday 01 hrs.
But i don't know the date for coming wednesday. Is
there any function available which returns the date
for this coming wednesday. And i don't want to add 3
to the DAY_OF_MONTH part.Your loose specification makes it difficult to be sure what you want but try this.
    public static void main(String[] args)
        // Now
        GregorianCalendar calendar = new GregorianCalendar();
        long nowInMilliseconds = calendar.getTime().getTime();
        // Move on to next wednesday
        while (calendar.get(Calendar.DAY_OF_WEEK) != Calendar.WEDNESDAY)
            calendar.add(Calendar.DAY_OF_YEAR, 1);
        // Set to 1 am
        calendar.set(Calendar.HOUR_OF_DAY, 1);
        calendar.set(Calendar.MINUTE, 0);
        calendar.set(Calendar.SECOND, 0);
        calendar.set(Calendar.MILLISECOND, 0);
        // Difference in ms
        long betweenNowAndNextWednesday = calendar.getTime().getTime() - nowInMilliseconds;
        System.out.println(betweenNowAndNextWednesday + " " + calendar.getTime());
    }It should not be too dififcult to generalise it!
