4*55e87721SMatt Gilbride
5*55e87721SMatt Gilbride  ``` java
6*55e87721SMatt Gilbride  import com.google.cloud.language.v1.LanguageServiceClient;
7*55e87721SMatt Gilbride  import com.google.cloud.language.v1.Document;
8*55e87721SMatt Gilbride  import com.google.cloud.language.v1.Document.Type;
9*55e87721SMatt Gilbride  import com.google.cloud.language.v1.Sentiment;
10*55e87721SMatt Gilbride  ```
11*55e87721SMatt Gilbride  Then, to analyze the sentiment of some text, use the following code:
12*55e87721SMatt Gilbride
13*55e87721SMatt Gilbride  ``` java
14*55e87721SMatt Gilbride  // Instantiates a client
15*55e87721SMatt Gilbride  LanguageServiceClient language = LanguageServiceClient.create();
16*55e87721SMatt Gilbride
17*55e87721SMatt Gilbride  // The text to analyze
18*55e87721SMatt Gilbride  String[] texts = {"I love this!", "I hate this!"};
19*55e87721SMatt Gilbride  for (String text : texts) {
20*55e87721SMatt Gilbride    Document doc = Document.newBuilder().setContent(text).setType(Type.PLAIN_TEXT).build();
21*55e87721SMatt Gilbride    // Detects the sentiment of the text
22*55e87721SMatt Gilbride    Sentiment sentiment = language.analyzeSentiment(doc).getDocumentSentiment();
23*55e87721SMatt Gilbride
24*55e87721SMatt Gilbride    System.out.printf("Text: \"%s\"%n", text);
25*55e87721SMatt Gilbride    System.out.printf(
26*55e87721SMatt Gilbride        "Sentiment: score = %s, magnitude = %s%n",
27*55e87721SMatt Gilbride        sentiment.getScore(), sentiment.getMagnitude());
