This method adds a receivable language.

public WebResource.Builder acceptLanguage(String... locales)

locales

This is an array of the receivable languages.

The method returns a builder (WebResource.Builder object) to set up the WebResource object.

• The non-null value in the locales parameter is added in the Accept-Language HTTP header. A null value is ignored and is not added in the Accept-Language HTTP header.
• The specified value is set as is in the Accept-Language HTTP header. The JAX-RS engine does not validate the specified value. Specify the value according to the standard specifications.
• You can also use the following methods to add the value of the Accept-Language HTTP header:
  
  • ClientRequest.Builder class
    acceptLanguage(Locale... locales) method
    acceptLanguage(String... locales) method
    header(String name, Object value) method
    
  • WebResource class
    acceptLanguage(Locale... locales) method
    header(String name, Object value) method
    
  • WebResource.Builder class
    acceptLanguage(Locale... locales) method
    acceptLanguage(String... locales) method
    header(String name, Object value) method
    
  The operation when no receivable language is added with these methods and the acceptLanguage(String... locales) method is the same as the operation when the Accept-Language HTTP header is not added in the HttpURLConnection object before performing HTTP communication.
