Método DateFormat setCalendar() en Java con ejemplos

El método setCalendar() de la clase DateFormat en Java se utiliza para configurar el calendario asociado con este objeto de formato de fecha/hora. En la etapa inicial, se utiliza la configuración predeterminada del calendario junto con la configuración regional predeterminada.

Parámetro: El método toma un parámetro new_calendar de tipo Calendar y hace referencia al nuevo Calendar con el que se reemplazará el objeto DateFormat original.

Valor devuelto: el método no devuelve ningún valor.

Los siguientes programas ilustran el uso del método setCalendar() en Java:
Ejemplo 1:

// Java code to illustrate
// setCalendar() 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("Original Calendar: "
                           + DFormat.getCalendar());
  
        // Creating a calendar
        Calendar calndr = Calendar.getInstance();
  
        // Replacing with a new value
        calndr.set(Calendar.MONTH, 11);
  
        // Setting new Calendar
        DFormat.setCalendar(calndr);
  
        System.out.println();
  
        // Displaying the newCalendar
        System.out.println("New Calendar: "
                           + DFormat.getCalendar());
    }
}

Producción:

Original Calendar: java.util.GregorianCalendar[time=1553847137520, 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=29, DAY_OF_YEAR=88, DAY_OF_WEEK=6, DAY_OF_WEEK_IN_MONTH=5, AM_PM=0, HOUR=8,
HOUR_OF_DAY=8, MINUTE=12, SECOND=17, MILLISECOND=520, ZONE_OFFSET=0, DST_OFFSET=0]

New Calendar: java.util.GregorianCalendar[time=?, areFieldsSet=false, 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,

Ejemplo 2:

// Java code to illustrate
// setCalendar() method
  
import java.text.*;
import java.util.*;
  
public class DateFormat_Demo {
    public static void main(String[] argv)
    {
        // Initializing the first formatter
        DateFormat DFormat
            = DateFormat.getDateInstance();
  
        // String formatting
        String str = DFormat.format(new Date());
  
        // Displaying the Calendar
        System.out.println("Original Calendar: "
                           + DFormat.getCalendar());
  
        // Creating a calendar
        Calendar calndr = Calendar.getInstance();
  
        // Replacing with a new value
        calndr.set(Calendar.YEAR, 1996);
  
        // Setting new Calendar
        DFormat.setCalendar(calndr);
        System.out.println();
        // Displaying the newCalendar
        System.out.println("New Calendar: "
                           + DFormat.getCalendar());
    }
}
