com.ibm.icu.util.ULocale
Builder is used to build instances of ULocale from values configured by the setters. Unlike the ULocale constructors, the Builder checks if a value configured by a setter satisfies the syntax requirements defined by the ULocale class. A ULocale object created by a Builder is well-formed and can be transformed to a well-formed IETF BCP 47 language tag without losing information.
Note: The ULocale class does not provide any syntactic restrictions on variant, while BCP 47 requires each variant subtag to be 5 to 8 alphanumerics or a single numeric followed by 3 alphanumerics. The method setVariant throws IllformedLocaleException for a variant that does not satisfy this restriction. If it is necessary to support such a variant, use a ULocale constructor. However, keep in mind that a ULocale object created this way might lose the variant information when transformed to a BCP 47 language tag.
The following example shows how to create a Locale object with the Builder.
```
 ULocale aLocale = new Builder().setLanguage("sr").setScript("Latn").setRegion("RS").build(); 
```
Builders can be reused; clear() resets all fields to their default values. @see ULocale#toLanguageTag() @stable ICU 4.2
