Google Natural Language API with Java setLanguage

I am using the Google Natural Language API to analyze entities from different texts. Is there a way to change the language of the input text to, for example english, as it is the case with the AlchemyAPI with

service.setLanguage (LanguageSelection.ENGLISH);

thanks

You specify the language via the relevant ISO or BCP-47 tag in the Document part of the request. So for example:

Document document = Document.newBuilder()
    .setLanguage("en")
    .set... // Call other setters
    .build();
