cal1.setTime(date1);
cal2.setTime(date2);
boolean sameDay = cal1.get(Calendar.YEAR) == cal2.get(Calendar.YEAR) &&
    cal1.get(Calendar.DAY_OF_YEAR) == cal2.get(Calendar.DAY_OF_YEAR);
Copy after login

Calendar.YEAR can get which date it is Year, use cal1.get(Calendar.YEAR) == cal2.get(Calendar.YEAR) to determine whether two dates are in the same year.

The main function of Calendar.DAY_OF_YEAR is cal.get(DAY_OF_YEAR), which is used to get the day of the year that this day is.
