All Implemented Interfaces:: Serializable, Cloneable

public final class Locale
extends Object
implements Cloneable, Serializable

Locale represents a language/country/variant combination. Locales are used to alter the presentation of information such as numbers or dates to suit the conventions in the region they describe.

The language codes are two-letter lowercase ISO language codes (such as "en") as defined by ISO 639-1. The country codes are two-letter uppercase ISO country codes (such as "US") as defined by ISO 3166-1. The variant codes are unspecified.

Note that Java uses several deprecated two-letter codes. The Hebrew ("he") language code is rewritten as "iw", Indonesian ("id") as "in", and Yiddish ("yi") as "ji". This rewriting happens even if you construct your own Locale object, not just for instances returned by the various lookup methods.

Available locales

This class' constructors do no error checking. You can create a Locale for languages and countries that don't exist, and you can create instances for combinations that don't exist (such as "de_US" for "German as spoken in the US").

Note that locale data is not necessarily available for any of the locales pre-defined as constants in this class except for en_US, which is the only locale Java guarantees is always available.

It is also a mistake to assume that all devices have the same locales available. A device sold in the US will almost certainly support en_US and es_US, but not necessarily any locales with the same language but different countries (such as en_GB or es_ES), nor any locales for other languages (such as de_DE). The opposite may well be true for a device sold in Europe.

You can use getDefault() to get an appropriate locale for the user of the device you're running on, or getAvailableLocales() to get a list of all the locales available on the device you're running on.

Locale data

Note that locale data comes solely from ICU. User-supplied locale service providers (using the java.text.spi or java.util.spi mechanisms) are not supported.

Here are the versions of ICU (and the corresponding CLDR and Unicode versions) used in various Android releases:

Android 1.5 (Cupcake)/Android 1.6 (Donut)/Android 2.0 (Eclair)	ICU 3.8	CLDR 1.5	Unicode 5.0
Android 2.2 (Froyo)	ICU 4.2	CLDR 1.7	Unicode 5.1
Android 2.3 (Gingerbread)/Android 3.0 (Honeycomb)	ICU 4.4	CLDR 1.8	Unicode 5.2
Android 4.0 (Ice Cream Sandwich)	ICU 4.6	CLDR 1.9	Unicode 6.0
Android 4.1 (Jelly Bean)	ICU 4.8	CLDR 2.0	Unicode 6.0
Android 4.3 (Jelly Bean MR2)	ICU 50	CLDR 22.1	Unicode 6.2
Android 4.4 (KitKat)	ICU 51	CLDR 23	Unicode 6.2
Android 5.0 (Lollipop)	ICU 53	CLDR 25	Unicode 6.3
Android 6.0 (Marshmallow)	ICU 55.1	CLDR 27.0.1	Unicode 7.0

Be wary of the default locale

Note that there are many convenience methods that automatically use the default locale, but using them may lead to subtle bugs.

The default locale is appropriate for tasks that involve presenting data to the user. In this case, you want to use the user's date/time formats, number formats, rules for conversion to lowercase, and so on. In this case, it's safe to use the convenience methods.

The default locale is not appropriate for machine-readable output. The best choice there is usually Locale.US – this locale is guaranteed to be available on all devices, and the fact that it has no surprising special cases and is frequently used (especially for computer-computer communication) means that it tends to be the most efficient choice too.

A common mistake is to implicitly use the default locale when producing output meant to be machine-readable. This tends to work on the developer's test devices (especially because so many developers use en_US), but fails when run on a device whose user is in a more complex locale.

For example, if you're formatting integers some locales will use non-ASCII decimal digits. As another example, if you're formatting floating-point numbers some locales will use ',' as the decimal point and '.' for digit grouping. That's correct for human-readable output, but likely to cause problems if presented to another computer (Double.parseDouble(java.lang.String) can't parse such a number, for example). You should also be wary of the String.toLowerCase() and String.toUpperCase() overloads that don't take a Locale: in Turkey, for example, the characters 'i' and 'I' won't be converted to 'I' and 'i'. This is the correct behavior for Turkish text (such as user input), but inappropriate for, say, HTTP headers.

  - clone
```
public Object clone()
```
    Description copied from class: Object
    
    Creates and returns a copy of this Object. The default implementation returns a so-called "shallow" copy: It creates a new instance of the same class and then copies the field values (including object references) from this instance to the new instance. A "deep" copy, in contrast, would also recursively clone nested objects. A subclass that needs to implement this kind of cloning should call super.clone() to create the new instance and then create deep copies of the nested, mutable objects.
    
    Overrides:
    
    clone in class Object
    
    Returns:
    
    a copy of this object.
  - equals
```
public boolean equals(Object object)
```
    Returns true if object is a locale with the same language, country and variant.
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    object - the object to compare this instance with.
    
    Returns:
    
    true if the specified object is equal to this Object; false otherwise.

    Object.hashCode()
  - getAvailableLocales
```
public static Locale[] getAvailableLocales()
```
    Returns the system's installed locales. This array always includes Locale.US, and usually several others. Most locale-sensitive classes offer their own getAvailableLocales method, which should be preferred over this general purpose method.
    
    See Also:
    
    BreakIterator.getAvailableLocales(), Collator.getAvailableLocales(), DateFormat.getAvailableLocales(), DateFormatSymbols.getAvailableLocales(), DecimalFormatSymbols.getAvailableLocales(), NumberFormat.getAvailableLocales(), Calendar.getAvailableLocales()
  - getCountry
```
public String getCountry()
```
    Returns the country code for this locale, or "" if this locale doesn't correspond to a specific country.
  - getDefault
```
public static Locale getDefault()
```
    Returns the user's preferred locale. This may have been overridden for this process with setDefault(java.util.Locale).
    Since the user's locale changes dynamically, avoid caching this value. Instead, use this method to look it up for each use.
  - getDisplayCountry
```
public final String getDisplayCountry()
```
    Equivalent to getDisplayCountry(Locale.getDefault()).
  - getDisplayCountry
```
public String getDisplayCountry(Locale locale)
```
    Returns the name of this locale's country, localized to locale. Returns the empty string if this locale does not correspond to a specific country.
  - getDisplayLanguage
```
public final String getDisplayLanguage()
```
    Equivalent to getDisplayLanguage(Locale.getDefault()).
  - getDisplayLanguage
```
public String getDisplayLanguage(Locale locale)
```
    Returns the name of this locale's language, localized to locale. If the language name is unknown, the language code is returned.
  - getDisplayName
```
public final String getDisplayName()
```
    Equivalent to getDisplayName(Locale.getDefault()).
  - getDisplayName
```
public String getDisplayName(Locale locale)
```
    Returns this locale's language name, country name, and variant, localized to locale. The exact output form depends on whether this locale corresponds to a specific language, script, country and variant.
    For example:
    
    new Locale("en").getDisplayName(Locale.US) -> English
    new Locale("en", "US").getDisplayName(Locale.US) -> English (United States)
    new Locale("en", "US", "POSIX").getDisplayName(Locale.US) -> English (United States,Computer)
    Locale.fromLanguageTag("zh-Hant-CN").getDisplayName(Locale.US) -> Chinese (Traditional Han,China)
    new Locale("en").getDisplayName(Locale.FRANCE) -> anglais
    new Locale("en", "US").getDisplayName(Locale.FRANCE) -> anglais (États-Unis)
    new Locale("en", "US", "POSIX").getDisplayName(Locale.FRANCE) -> anglais (États-Unis,informatique).
  - getDisplayVariant
```
public final String getDisplayVariant()
```
    Returns the full variant name in the default Locale for the variant code of this Locale. If there is no matching variant name, the variant code is returned.
    
    Since:
    
    1.7
  - getDisplayVariant
```
public String getDisplayVariant(Locale locale)
```
    Returns the full variant name in the specified Locale for the variant code of this Locale. If there is no matching variant name, the variant code is returned.

  - getISO3Country
```
public String getISO3Country()
```
    Returns the three-letter ISO 3166 country code which corresponds to the country code for this Locale.
    
    Throws:
    
    MissingResourceException - if there's no 3-letter country code for this locale.
  - getISO3Language
```
public String getISO3Language()
```
    Returns the three-letter ISO 639-2/T language code which corresponds to the language code for this Locale.
    
    Throws:
    
    MissingResourceException - if there's no 3-letter language code for this locale.
  - getISOCountries
```
public static String[] getISOCountries()
```
    Returns an array of strings containing all the two-letter ISO 3166 country codes that can be used as the country code when constructing a Locale.
  - getISOLanguages
```
public static String[] getISOLanguages()
```
    Returns an array of strings containing all the two-letter ISO 639-1 language codes that can be used as the language code when constructing a Locale.
  - getLanguage
```
public String getLanguage()
```
    Returns the language code for this Locale or the empty string if no language was set.
  - getVariant
```
public String getVariant()
```
    Returns the variant code for this Locale or an empty String if no variant was set.
  - getScript
```
public String getScript()
```
    Returns the script code for this Locale or an empty String if no script was set. If set, the script code will be a title cased string of length 4, as per the ISO 15924 specification.
    
    Since:
    
    1.7
  - getDisplayScript
```
public String getDisplayScript()
```
    Equivalent to getDisplayScript(Locale.getDefault()))
    
    Since:
    
    1.7
  - getDisplayScript
```
public String getDisplayScript(Locale locale)
```
    Returns the name of this locale's script code, localized to Locale. If the script code is unknown, the return value of this method is the same as that of getScript().
    
    Since:
    
    1.7
  - toLanguageTag
```
public String toLanguageTag()
```
    Returns a well formed BCP-47 language tag that identifies this locale. Note that this locale itself might consist of ill formed fields, since the public Locale constructors do not perform validity checks to maintain backwards compatibility. When this is the case, this method will either replace ill formed fields with standard BCP-47 subtags (For eg. "und" (undetermined) for invalid languages) or omit them altogether. Additionally, ill formed variants will result in the remainder of the tag (both variants and extensions) being moved to the private use extension, where they will appear after a subtag whose value is "lvariant". It's also important to note that the BCP-47 tag is well formed in the sense that it is unambiguously parseable into its specified components. We do not require that any of the components are registered with the applicable registries. For example, we do not require scripts to be a registered ISO 15924 scripts or languages to appear in the ISO-639-2 code list.
    
    Since:
    
    1.7
  - getExtensionKeys
```
public Set<Character> getExtensionKeys()
```
    Returns the set of BCP-47 extensions this locale contains. See the IETF BCP-47 specification (Section 2.2.6) for details.
    
    Since:
    
    1.7
  - getExtension
```
public String getExtension(char extensionKey)
```
    Returns the BCP-47 extension whose key is extensionKey, or null if this locale does not contain the extension. Individual Keywords and attributes for the unicode locale extension can be fetched using getUnicodeLocaleAttributes(), getUnicodeLocaleKeys() and getUnicodeLocaleType(java.lang.String).
    
    Since:
    
    1.7
  - getUnicodeLocaleType
```
public String getUnicodeLocaleType(String keyWord)
```
    Returns the type for the specified unicode locale extension key. For more information about types and keywords, see Locale.Builder.setUnicodeLocaleKeyword(java.lang.String, java.lang.String) and Unicode Technical Standard #35
    
    Since:
    
    1.7
  - getUnicodeLocaleAttributes
```
public Set<String> getUnicodeLocaleAttributes()
```
    Returns the set of unicode locale extension attributes this locale contains. For more information about attributes, see Locale.Builder.addUnicodeLocaleAttribute(java.lang.String) and Unicode Technical Standard #35
    
    Since:
    
    1.7
  - getUnicodeLocaleKeys
```
public Set<String> getUnicodeLocaleKeys()
```
    Returns the set of unicode locale extension keywords this locale contains. For more information about types and keywords, see Locale.Builder.setUnicodeLocaleKeyword(java.lang.String, java.lang.String) and Unicode Technical Standard #35
    
    Since:
    
    1.7
  - hashCode
```
public int hashCode()
```
    Description copied from class: Object
    
    Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.
    Note that hash values must not change over time unless information used in equals comparisons also changes.
    See Writing a correct hashCode method if you intend implementing your own hashCode method.
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    this object's hash code.
    
    See Also:
    
    Object.equals(java.lang.Object)
  - setDefault
```
public static void setDefault(Locale locale)
```
    Overrides the default locale. This does not affect system configuration, and attempts to override the system-provided default locale may themselves be overridden by actual changes to the system configuration. Code that calls this method is usually incorrect, and should be fixed by passing the appropriate locale to each locale-sensitive method that's called.
  - toString
```
public final String toString()
```
    Returns the string representation of this Locale. It consists of the language code, country code and variant separated by underscores. If the language is missing the string begins with an underscore. If the country is missing there are 2 underscores between the language and the variant. The variant cannot stand alone without a language and/or country code: in this case this method would return the empty string.
    Examples: "en", "en_US", "_US", "en__POSIX", "en_US_POSIX"
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    a printable representation of this object.
  - serializeExtensions
```
public static String serializeExtensions(Map<Character,String> extensionsMap)
```
    The serialized form for extensions is straightforward. It's simply of the form key1-value1-key2-value2 where each value might in turn contain multiple subtags separated by hyphens. Each key is guaranteed to be a single character in length. This method assumes that extensionsMap is non-empty. Visible for testing.
  - parseSerializedExtensions
```
public static void parseSerializedExtensions(String extString,
                                             Map<Character,String> outputMap)
```
    Visible for testing.
  - parseUnicodeExtension
```

```
    This extension is described by http://www.unicode.org/reports/tr35/#RFC5234 unicode_locale_extensions = sep "u" (1*(sep keyword) / 1*(sep attribute) *(sep keyword)). It must contain at least one keyword or attribute and attributes (if any) must appear before keywords. Attributes can't appear after keywords because they will be indistinguishable from a subtag of the keyword type. Visible for testing.
