问我想从Java日期中获取年、月、日等，以便与Java中的公历日期进行比较。这个是可能的吗？

EN

Date date = new Date();
LocalDate localDate = date.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
int year  = localDate.getYear();
int month = localDate.getMonthValue();
int day   = localDate.getDayOfMonth();

String currentDateString = "02/27/2012 17:00:00";
SimpleDateFormat sd = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
Date currentDate = sd.parse(currentDateString);

String yourDateString = "02/28/2012 15:00:00";
SimpleDateFormat yourDateFormat = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");

Date yourDate = yourDateFormat.parse(yourDateString);

if (yourDate.after(currentDate)) {
    System.out.println("After");
} else if(yourDate.equals(currentDate)) {
    System.out.println("Same");
} else {
    System.out.println("Before");
}

    Date date = new Date();

    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("EEEE");

    System.out.println("DAY "+simpleDateFormat.format(date).toUpperCase());

    simpleDateFormat = new SimpleDateFormat("MMMM");
    System.out.println("MONTH "+simpleDateFormat.format(date).toUpperCase());

    simpleDateFormat = new SimpleDateFormat("YYYY");
    System.out.println("YEAR "+simpleDateFormat.format(date).toUpperCase());

DAY FRIDAY
MONTH JUNE
YEAR 2018
