示例1:

// Java code to illustrate 
// getCalendar() method 
  
import java.text.*; 
import java.util.*; 
  
public class DateFormat_Demo { 
    public static void main(String[] argv) 
    { 
        // Initializing the first formatter 
        DateFormat DFormat 
            = DateFormat.getDateTimeInstance(); 
  
        // String formatting 
        String str = DFormat.format(new Date()); 
  
        // Displaying the Calendar 
        System.out.println(DFormat.getCalendar()); 
    } 
}

输出：

java.util.GregorianCalendar[time=1553691245240, areFieldsSet=true, areAllFieldsSet=true,
lenient=true, zone=sun.util.calendar.ZoneInfo[id="Etc/UTC", offset=0, dstSavings=0,
useDaylight=false, transitions=0, lastRule=null], firstDayOfWeek=1, minimalDaysInFirstWeek=1,
ERA=1, YEAR=2019, MONTH=2, WEEK_OF_YEAR=13, WEEK_OF_MONTH=5, DAY_OF_MONTH=27, DAY_OF_YEAR=86,
DAY_OF_WEEK=4, DAY_OF_WEEK_IN_MONTH=4, AM_PM=1, HOUR=0, HOUR_OF_DAY=12, MINUTE=54, SECOND=5,
MILLISECOND=240, ZONE_OFFSET=0, DST_OFFSET=0]

示例2:

// Java code to illustrate 
// getCalendar() method 
  
import java.text.*; 
import java.util.*; 
  
public class DateFormat_Demo { 
    public static void main(String[] argv) 
    { 
        // Initializing the first formatter 
        DateFormat DFormat 
            = new SimpleDateFormat("MM/ dd/ yy"); 
  
        // String formatting 
        String str = DFormat.format(new Date()); 
  
        // Displaying the Calendar 
        System.out.println(DFormat.getCalendar()); 
    } 
}

输出：

java.util.GregorianCalendar[time=1553691264669, areFieldsSet=true, areAllFieldsSet=true,
lenient=true, zone=sun.util.calendar.ZoneInfo[id="Etc/UTC", offset=0, dstSavings=0,
useDaylight=false, transitions=0, lastRule=null], firstDayOfWeek=1, minimalDaysInFirstWeek=1,
ERA=1, YEAR=2019, MONTH=2, WEEK_OF_YEAR=13, WEEK_OF_MONTH=5, DAY_OF_MONTH=27, DAY_OF_YEAR=86,
DAY_OF_WEEK=4, DAY_OF_WEEK_IN_MONTH=4, AM_PM=1, HOUR=0, HOUR_OF_DAY=12, MINUTE=54, SECOND=24,
