Google Translate API in Java

Posted by
October 22, 2008
  

This APi is not official Google API but an open source project hosted at google code. This API provides a simple, unofficial, Java client API for using Google Translate. You can download the jar file and include it in your path for using it.

Below is the example code which i used to convert set of resource files into Hindi langauge using Google Translate

 
import com.google.api.translate.Language;
import com.google.api.translate.Translate;
 
public class GoogleTranslator {
 
	*//**
	 * @param args
	 *//*
	public static void main(String[] args) {
		try {
                      String translatedText = Translate.translate("How are you?",
				    	                        Language.ENGLISH, Language.HINDI);
		       System.out.println(translatedText);
		} catch (Exception ex) {
			ex.printStackTrace();
		}
	}
}
 

This project has only two classes which are imported in above example.

a) Language Class: This class contain all languages supported by Google Translate as of now and helps him select his language than give intelligent string inputs in translate function.

b) Translate Class: This class do the real work of translation. This uses ajax google api for language to do the translation from one language to other.

String translatedText = Translate.execute(“Salut le monde”, Language.FRENCH, Language.ENGLISH);

System.out.println(translatedText);
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
