Question

I have the following code for getting the last Sunday before the current date:

Calendar calendar=Calendar.getInstance();
calendar.set(Calendar.WEEK_OF_YEAR, calendar.get(Calendar.WEEK_OF_YEAR)-1);
calendar.set(Calendar.DAY_OF_WEEK, Calendar.SUNDAY);
Log.e("first day", String.valueOf(calendar.get(Calendar.DAY_OF_MONTH)));

But this code doesn’t work. Please, tell me, how can I fix it?

Answer 1

This will work. We first get the day count, and then subtract that with the current day and add 1 ( for sunday)

Calendar cal=Calendar.getInstance();
cal.add( Calendar.DAY_OF_WEEK, -(cal.get(Calendar.DAY_OF_WEEK)-1)); 
System.out.println(cal.get(Calendar.DATE));

Edit : As pointed out by Basil Bourque in the comment, see the answer by Grzegorz Gajos for Java 8 and later.
