public static String getDateTime() {
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MMMM dd, yyyy HH:mm:ss", Locale.getDefault());
        Date date = new Date();
        return simpleDateFormat.format(date);
    }

LocalDateTime ldt2 = LocalDateTime.now();
String year = ldt2.getYear()+"";
String month = ldt2.getMonthValue()+"";
String date = ldt2.getDayOfMonth()+"";
String hour = ldt2.getHour()+"";
String minute = ldt2.getMinute()+"";
String secs = ldt2.getSecond()+"";

 public String giveDate() {
    Calendar cal = Calendar.getInstance();
    SimpleDateFormat sdf = new SimpleDateFormat("EEE, MMM d, yyyy");
    return sdf.format(cal.getTime());
 }

CharSequence s  = DateFormat.getDateInstance().format("MMMM d, yyyy ");

首先需要一个实例

工作就像一个魅力和转换为字符串作为奖励;)

SimpleDateFormat currentDate = new SimpleDateFormat("dd/MM/yyyy");
      Date todayDate = new Date();
    String thisDate = currentDate.format(todayDate);

此方法可用于从系统中获取当前日期。

public static String getCurrentDateAndTime(){
    Date c = Calendar.getInstance().getTime();
    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy/MM/dd");
    String formattedDate = simpleDateFormat.format(c);
    return formattedDate;
}
