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.





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)
LanguageDetectionApi apiInstance = new LanguageDetectionApi();
String textToDetect = "textToDetect_example"; // String | Text to detect language of
try {
LanguageDetectionResponse result = apiInstance.languageDetectionPost(textToDetect);
} catch (ApiException e) {
System.err.println("Exception when calling LanguageDetectionApi#languageDetectionPost");

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.
