Answer 1

Or Just do some simple math. Since Calender.Monday equals 2, it is easy to calculate the number of days that need to be added to the current date.

Calendar date1 = Calendar.getInstance();
date1.set(2014, 05, 12);
int dayOfWeek = date1.get(Calendar.DAY_OF_WEEK);
date1.add(Calendar.DATE, (9 - dayOfWeek) % 7);
