How to use Google Translate API in Java application ?

You can do the language translation using Google Translate API. Below is the Java code for integration.

import java.util.Arrays;

import com.google.api.client.googleapis.javanet.GoogleNetHttpTransport;

import com.google.api.client.json.gson.GsonFactory;

import com.google.api.services.translate.Translate;

import com.google.api.services.translate.model.TranslationsListResponse;

import com.google.api.services.translate.model.TranslationsResource;

public class GoogleTranslationAPISample {

public static void main(String[] arguments) throws GeneralSecurityException, IOException 

    {

        Translate t = new Translate.Builder(

                GoogleNetHttpTransport.newTrustedTransport()

                , GsonFactory.getDefaultInstance(), null)

// Set your application name

                .setApplicationName("sample-Example")

                .build();

        Translate.Translations.List list = t.new Translations().list(

                Arrays.asList(

// Pass in list of strings to be translated

                "Hello World",

                "How to use Google Translate from Java"),

// Target language

                "es"); // es for spanish

// TODO: Set your API-Key from https://console.developers.google.com/

// list.setKey("your-api-key");

        

//list.setKey("AIdwaSyCAKK7htoeT8i8ArmITELoDMyuiorooe5wk-cKs5g"); // my test credentials

        TranslationsListResponse response = list.execute();

        for (TranslationsResource translationsResource : response.getTranslations())

        {

            System.out.println(translationsResource.getTranslatedText());

        }

    }

}
