  1. class Locale 1/3 • Constructor Locale(String, String) Construct a locale from language, country. Locale(String, String, String) Construct a locale from language, country, variant. • Methods clone() equals(Object) getCountry() uppercased two-letter ISO-3166 getDefault() getDisplayCountry() getDisplayCountry(Locale) getDisplayLanguage() getDisplayLanguage(Locale) getDisplayName() getDisplayName(Locale) getDisplayVariant() getDisplayVariant(Locale) getISO3Country() three-letter ISO country abbreviation getISO3Language() three-letter ISO language abbreviation getLanguage() lowercased two-letter ISO-639 getVariant() hashCode() setDefault(Locale) toString()

  4. class TimeZone 1/5 • Constructor TimeZone() • Methods clone() Overrides Cloneable getAvailableIDs() Gets all the available IDs supported. getAvailableIDs(int) getDefault() getID() Gets the ID of this time zone. getOffset(int, int, int, int, int, int) Gets the time zone offset, for current date, modified in case of daylight savings. getRawOffset() Gets unmodified offset, NOT modified in case of daylight savings. getTimeZone(String) Gets the TimeZone for the given ID. inDaylightTime(Date) Queries if the given date is in Daylight Savings Time in this time zone. setDefault(TimeZone) setID(String) Sets the time zone ID. setRawOffset(int) Sets the base time zone offset to GMT. useDaylightTime() Queries if this time zone uses Daylight Savings Time.

  5. class TimeZone 2/5 • Abstract Class. • TimeZone represents a time zone offset, and also figures out daylight savings. • TimeZone tz = TimeZone.getTimeZone("PST"); • Typically, you get a TimeZone using getDefault which creates a TimeZone based on the time zone where the program is running. For example, for a program running in Japan, getDefault creates a TimeZone object based on Japanese Standard Time.

  6. class TimeZone 3/5 public static synchronized String[] getAvailableIDs() public static synchronized TimeZone getDefault() Gets the default TimeZone for this host. public abstract boolean inDaylightTime(Date date) Queries if the given date is in Daylight Savings Time in this time zone. public abstract boolean useDaylightTime() Queries if this time zone uses Daylight Savings Time. public abstract int getRawOffset() Gets unmodified offset, NOT modified in case of daylight savings. This is the offset to add *to* UTC to get local time. public static synchronized TimeZone getDefault() Gets the default TimeZone for this host.

  7. class TimeZone 4/5 public class TimeZoneTest { public static void main( String args[ ] ) { //TimeZone Test = new TimeZone( ); System.out.println( TimeZone.getDefault( ) ); //System.out.println( Test.getRawOffset( ) ); String Test2[ ]; Test2=TimeZone.getAvailableIDs System.out.println( Test2.length - 1 ); for(inti=0;i<Test2.length;i++) { System.out.println( Test2[ i ] ); } } }

  9. class ResourceBundle 1/3 • Constructor ResourceBundle() • Methods getBundle(String) Get the appropriate ResourceBundle subclass. GetBundle(String, Loca) Get the appropriate ResourceBundle subclass. getKeys() Return an enumeration of the keys. getObject(String) Get an object from a ResourceBundle. getString(String) Get an object from a ResourceBundle. getStringArray(String) Get an object from a ResourceBundle. handleGetObject(String) Get an object from a ResourceBundle. setParent(ResourceBundle) Set the parent bundle of this bundle.

  10. class ResourceBundle 2/3 • This allows you to write programs that can: • be easily localized, or translated, into different languages • handle multiple locales at once • be easily modified later to support even more locales • baseclass must be fully qualified : myPackage.MyResources • baseclass with no suffixes baseclass + "_" + language1 + "_" + country1 + "_" + variant1 baseclass + "_" + language1 + "_" + country1 baseclass + "_" + language1 baseclass baseclass + "_" + language2 + "_" + country2 + "_" + variant2 baseclass + "_" + language2 + "_" + country2 baseclass + "_" + language2 • key/value pairs : keys are always Strings • parent • handleGetObject( String key ), getKeys( ) • only these are abstract methods.
