The setUnicodeLocaleKeyword() method of java.util.Locale.Builder class in Java is used to set this Locale.Builder to the specified unicodeLocaleKeyword key. It means that this method will set the current unicodeLocaleKeyword of Locale.Builder instance to match the provided unicodeLocaleKeyword key and type and return it. If the specified unicodeLocaleKeyword is null or empty, then the unicodeLocaleKeyword of this LocaleBuilder is removed.
Syntax:
public Locale.Builder
setUnicodeLocaleKeyword(
String unicodeLocaleKeywordKey,
String unicodeLocaleKeywordType)
Parameter: This method accepts two parameters:
- unicodeLocaleKey: which is the key String that is to be set to this Locale.Builder instance for the unicode Locale
- unicodeLocaleKeywordType: which is the type String that is to be set to this Locale.Builder instance for the unicode Locale
Return Type: This method returns an Locale.Builder instance with the unicodeLocaleKeyword set of this Locale.Builder to the specified unicodeLocaleKeyword.
Exception: This method throws following Exceptions:
- IllformedLocaleException: if the specified unicodeLocaleKeyword has any ill formed fields
