How to detect the language of a string in Java

Today we shall look at how to implement language detection quickly and easily using a Cloudmersive API. Let’s get started.

The library we will be using must be compiled dynamically with Jitpack. So we will first set up our references in Maven POM.

Repository:

<repositories>
<repository>
<id>jitpack.io</id>
<url>https://jitpack.io</url>
</repository>
</repositories>

Dependency:

<dependencies>
<dependency>
<groupId>com.github.Cloudmersive</groupId>
<artifactId>Cloudmersive.APIClient.Java</artifactId>
<version>v2.32</version>
</dependency>
</dependencies>

Now we just have to call languageDetectionPost:

// Import classes:
//import com.cloudmersive.client.invoker.ApiClient;
//import com.cloudmersive.client.invoker.ApiException;
//import com.cloudmersive.client.invoker.Configuration;
//import com.cloudmersive.client.invoker.auth.*;
//import com.cloudmersive.client.LanguageDetectionApi;
ApiClient defaultClient = Configuration.getDefaultApiClient();// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) defaultClient.getAuthentication("Apikey");
Apikey.setApiKey("YOUR API KEY");
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.setApiKeyPrefix("Token");
LanguageDetectionApi apiInstance = new LanguageDetectionApi();
String textToDetect = "textToDetect_example"; // String | Text to detect language of
try {
LanguageDetectionResponse result = apiInstance.languageDetectionPost(textToDetect);
System.out.println(result);
} catch (ApiException e) {
System.err.println("Exception when calling LanguageDetectionApi#languageDetectionPost");
e.printStackTrace();
}

And that’s all there is to it. Let’s look at an example with the input string “gemutlicheit.” Our output:

{
"Successful": true,
"DetectedLanguage_ThreeLetterCode": "DEU",
"DetectedLanguage_FullName": "German"
}

As you can see we are told whether the function was successful, the full name of the language, and a three letter code for the language.

There’s an API for that. Cloudmersive is a leader in Highly Scalable Cloud APIs.
