private void readObject(ObjectInputStream stream)
                 throws IOException,
                        ClassNotFoundException
```
      Reconstitutes this object from a stream (i.e., deserialize it).

private void writeObject(ObjectOutputStream stream)
                  throws IOException
```
      Save the state of this object to a stream (i.e., serialize it). Ideally, Calendar would only write out its state data and the current time, and not write any field data out, such as fields[], isTimeSet, areFieldsSet, and isSet[]. nextStamp also should not be part of the persistent state. Unfortunately, this didn't happen before JDK 1.1 shipped. To be compatible with JDK 1.1, we will always have to write out the field values and state flags. However, nextStamp can be removed from the serialization stream; this will probably happen in the near future.
      
      Throws:
      
      IOException
  - Serialized Fields
    - fields
```
int[] fields
```
      The calendar field values for the currently set time for this calendar. This is an array of FIELD_COUNT integers, with index values ERA through DST_OFFSET.
    - isSet
```
boolean[] isSet
```
      The flags which tell if a specified calendar field for the calendar is set. A new object has no fields set. After the first call to a method which generates the fields, they all remain set after that. This is an array of FIELD_COUNT booleans, with index values ERA through DST_OFFSET.
    - time
```
long time
```
      The currently set time for this calendar, expressed in milliseconds after January 1, 1970, 0:00:00 GMT.
      
      See Also:
      
      Calendar.isTimeSet
    - isTimeSet
```
boolean isTimeSet
```
      True if then the value of time is valid. The time is made invalid by a change to an item of field[].
      
      See Also:
      
      Calendar.time
    - areFieldsSet
```
boolean areFieldsSet
```
      True if fields[] are in sync with the currently set time. If false, then the next attempt to get the value of a field will force a recomputation of all fields from the current value of time.
    - lenient
```
boolean lenient
```
      True if this calendar allows out-of-range field values during computation of time from fields[].
      
      See Also:
      
      Calendar.setLenient(boolean), Calendar.isLenient()
    - zone
```
TimeZone zone
```
      The TimeZone used by this calendar. Calendar uses the time zone data to translate between locale and GMT time.
    - firstDayOfWeek
```
int firstDayOfWeek
```
      The first day of the week, with possible values SUNDAY, MONDAY, etc. This is a locale-dependent value.
    - minimalDaysInFirstWeek
```
int minimalDaysInFirstWeek
```
      The number of days required for the first week in a month or year, with possible values from 1 to 7. This is a locale-dependent value.
    - nextStamp
```
int nextStamp
```
      The next available value for stamp[], an internal array. This actually should not be written out to the stream, and will probably be removed from the stream in the near future. In the meantime, a value of MINIMUM_USER_STAMP should be used.
    - serialVersionOnStream
```
int serialVersionOnStream
```
      The version of the serialized data on the stream. Possible values:
      
      0 or not present on stream
      
      JDK 1.1.5 or earlier.
      
      1
      
      JDK 1.1.6 or later. Writes a correct 'time' value as well as compatible values for other fields. This is a transitional format.
      
      When streaming out this class, the most recent format and the highest allowable serialVersionOnStream is written.

      SynchronizedRandomAccessList instances are serialized as SynchronizedList instances to allow them to be deserialized in pre-1.4 JREs (which do not have SynchronizedRandomAccessList). This method inverts the transformation. As a beneficial side-effect, it also grafts the RandomAccess marker onto SynchronizedList instances that were serialized in pre-1.4 JREs. Note: Unfortunately, SynchronizedRandomAccessList instances serialized in 1.4.1 and deserialized in 1.4 will become SynchronizedList instances, as this method was missing in 1.4.

      Serial Data:
      
      We write out two formats, a JDK 1.1 compatible format, using DOW_IN_MONTH_MODE rules, in the required section, followed by the full rules, in packed format, in the optional section. The optional section will be ignored by JDK 1.1 code upon stream in.
      Contents of the optional section: The length of a byte array is emitted (int); this is 4 as of this release. The byte array of the given length is emitted. The contents of the byte array are the true values of the fields startDay, startDayOfWeek, endDay, and endDayOfWeek. The values of these fields in the required section are approximate values suited to the rule mode DOW_IN_MONTH_MODE, which is the only mode recognized by JDK 1.1.

  - Serialized Fields
    - startMonth
```
int startMonth
```
      The month in which daylight saving time starts. This value must be between Calendar.JANUARY and Calendar.DECEMBER inclusive. This value must not equal endMonth.
      If useDaylight is false, this value is ignored.
    - startDay
```
int startDay
```
      This field has two possible interpretations:
      
      startMode == DOW_IN_MONTH

      startMode != DOW_IN_MONTH
      
      startDay indicates which startDayOfWeek in the month startMonth daylight saving time starts on. For example, a value of +1 and a startDayOfWeek of Calendar.SUNDAY indicates the first Sunday of startMonth. Likewise, +2 would indicate the second Sunday, and -1 the last Sunday. A value of 0 is illegal.
      
      If useDaylight is false, this value is ignored.
    - startDayOfWeek
```
int startDayOfWeek
```
      The day of the week on which daylight saving time starts. This value must be between Calendar.SUNDAY and Calendar.SATURDAY inclusive.
      If useDaylight is false or startMode == DAY_OF_MONTH, this value is ignored.
    - startTime
```
int startTime
```

      If useDaylight is false, this value is ignored.
    - endDay
```
int endDay
```
      This field has two possible interpretations:
      
      endMode == DOW_IN_MONTH
      
      endDay indicates the day of the month of endMonth on which daylight saving time ends, from 1 to 28, 30, or 31, depending on the endMonth.
      
      endMode != DOW_IN_MONTH
      
      endDay indicates which endDayOfWeek in th month endMonth daylight saving time ends on. For example, a value of +1 and a endDayOfWeek of Calendar.SUNDAY indicates the first Sunday of endMonth. Likewise, +2 would indicate the second Sunday, and -1 the last Sunday. A value of 0 is illegal.
      
      If useDaylight is false, this value is ignored.
    - endDayOfWeek
```

    - endTime
```
int endTime
```
      The time in milliseconds after midnight at which daylight saving time ends. This value is expressed as wall time, standard time, or UTC time, depending on the setting of endTimeMode.
      If useDaylight is false, this value is ignored.
    - endTimeMode
```
int endTimeMode
```
      The format of endTime, either WALL_TIME, STANDARD_TIME, or UTC_TIME.
      
      Since:
      
      1.3
    - startYear
```
int startYear
```
      The year in which daylight saving time is first observed. This is an AD value. If this value is less than 1 then daylight saving time is observed for all AD years.
      If useDaylight is false, this value is ignored.
    - rawOffset
```
int rawOffset
```
      The offset in milliseconds between this zone and GMT. Negative offsets are to the west of Greenwich. To obtain local standard time, add the offset to GMT time. To obtain local wall time it may also be necessary to add dstSavings.
    - useDaylight
```
boolean useDaylight
```
      A boolean value which is true if and only if this zone uses daylight saving time. If this value is false, several other fields are ignored.
    - monthLength
```
byte[] monthLength
```
      This field was serialized in JDK 1.1, so we have to keep it that way to maintain serialization compatibility. However, there's no need to recreate the array each time we create a new time zone.
      
      An array of bytes containing the values {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}. This is ignored as of the Java 2 platform v1.2, however, it must be streamed out for compatibility with JDK 1.1.
    - startMode
```
int startMode
```
      Variables specifying the mode of the start rule. Takes the following values:
      
      DOM_MODE
