How to use Google Translate API in my Java application?

Question

If I pass a string (either in English or Arabic) as an input to the Google Translate API, it should translate it into the corresponding other language and give the translate

Answer 1

Generate your own API key here. Check out the documentation here.

You may need to set up a billing account when you try to enable the Google Cloud Translation API in your account.

Below is a quick start example which translates two English strings to Spanish:

import java.io.IOException;
import java.security.GeneralSecurityException;
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 QuickstartSample
{
    public static void main(String[] arguments) throws IOException, GeneralSecurityException
    {
        Translate t = new Translate.Builder(
                GoogleNetHttpTransport.newTrustedTransport()
                , GsonFactory.getDefaultInstance(), null)
                // Set your application name
                .setApplicationName("Stackoverflow-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");

        // TODO: Set your API-Key from https://console.developers.google.com/
        list.setKey("your-api-key");
        TranslationsListResponse response = list.execute();
        for (TranslationsResource translationsResource : response.getTranslations())
        {
            System.out.println(translationsResource.getTranslatedText());
        }
    }
}
