Java The Complete Reference, Seventh Edition

The secondSimpleTimeZoneconstructor is

SimpleTimeZone(inttimeDelta, StringtzId, intdstMonth0,

intdstDayInMonth0, intdstDay0, inttime0,

intdstMonth1, intdstDayInMonth1, intdstDay1,

inttime1)

Here, the offset relative to GMT is specified intimeDelta.The time zone name is passed intzId.

The start of daylight saving time is indicated by the parametersdstMonth0, dstDayInMonth0,

dstDay0,andtime0.The end of daylight saving time is indicated by the parametersdstMonth1,

dstDayInMonth1, dstDay1,andtime1.

The thirdSimpleTimeZoneconstructor is

SimpleTimeZone(inttimeDelta, StringtzId, intdstMonth0,

intdstDayInMonth0, intdstDay0, inttime0,

intdstMonth1, intdstDayInMonth1, intdstDay1,

inttime1, intdstDelta)

Here,dstDeltais the number of milliseconds saved during daylight saving time.

The fourthSimpleTimeZoneconstructor is

SimpleTimeZone(inttimeDelta, StringtzId, intdstMonth0,

intdstDayInMonth0, intdstDay0, inttime0,

inttime0mode, intdstMonth1, intdstDayInMonth1,

intdstDay1, inttime1, inttime1mode, intdstDelta)

Here,time0modespecifies the mode of the starting time, andtime1modespecifies the

mode of the ending time. Valid mode values include

STANDARD_TIME WALL_TIME UTC_TIME

The time mode indicates how the time values are interpreted. The default mode used by the

other constructors isWALL_TIME.

Locale

TheLocaleclass is instantiated to produce objects that describe a geographical or cultural

region. It is one of several classes that provide you with the ability to write programs that

can execute in different international environments. For example, the formats used to display

dates, times, and numbers are different in various regions.

Internationalization is a large topic that is beyond the scope of this book. However, many

programs will only need to deal with its basics, which include setting the current locale.

TheLocaleclass defines the following constants that are useful for dealing with the most

common locales:

CANADA GERMAN KOREAN

CANADA_FRENCH GERMANY PRC
