The necessary steps include:

1. Add the following imports to the project:

import java.util.ArrayList;
import java.util.HashMap;
import com.amazonaws.auth.AWSCredentialsProvider;
import com.amazonaws.auth.DefaultAWSCredentialsProviderChain;
import com.amazonaws.services.translate.AmazonTranslate;
import com.amazonaws.services.translate.AmazonTranslateClient;
import com.amazonaws.services.translate.model.TranslateTextRequest;
import com.amazonaws.services.translate.model.TranslateTextResult;

2. Add the following statements to the main method, which will declare the text to be translated:

ArrayList<String> textList = new ArrayList<>();
textList.add("Language is a system that consists of the development, "
    + "acquisition, maintenance and use of complex systems of "
    + "communication, particularly the human ability to do so; "
    + "and a language is any specific example of such a system.");
textList.add("Language ist ein Lied des US-amerikanischen DJs und "
    + "Musikproduzenten Porter Robinson, das von Heather Bright "
    + "gesungen und am 10. April 2012 auf Beatport veröffentlicht"
    + " wurde. Language kann dem Genre Electro House zugeordnet "
    + "werden und hat 128 bpm. Die Vollversion war bereits ab "
    + "dem 26. März 2012 bei YouTube anhörbar. Der Track ist "
    + "unter anderem auch auf dem Soundtrack von Forza Horizon enthalten.");

3. Follow the previous statements with code to access the Amazon credentials and set up a translation request as follows:

AWSCredentialsProvider awsCredentialsProvider = 
    DefaultAWSCredentialsProviderChain.getInstance();
AmazonTranslate amazonTranslate = AmazonTranslateClient.builder()
    .withCredentials(awsCredentialsProvider)
    .withRegion("us-east-2")
    .build();
TranslateTextRequest translateTextRequest = new TranslateTextRequest()
    .withText(textList.get(0))
    .withSourceLanguageCode("en")
    .withTargetLanguageCode("es");

4. Add the following code to perform the translation and display the results:

TranslateTextResult translateTextResult = 
    amazonTranslate.translateText(translateTextRequest);
System.out.println(translateTextResult.getTranslatedText());
System.out.println();

5. Execute the program. You will get the following output:

El lenguaje es un sistema que consiste en el desarrollo, adquisición, mantenimiento y uso de sistemas complejos de comunicación, en particular la capacidad humana para hacerlo; y un lenguaje es cualquier ejemplo específico de tal sistema.
