问题
I want to build a chat Application in JavaFx in which there will be a button that lets user switch between languages English and Hindi (Indian regional language).The problem is I am not able to figure out how am I suppose to change the language of text of a JavaFx Textbox when the user clicks the button. I have not yet started developing my project because of this problem. Plz just give me a demo program that changes the text in the textbox when a button is clicked.
Thanks!!!
EDIT: I Tried doing this, SOrry I have never use resource bundles or locales to change text dynamically so i dont know how to implement it....

Ok!!! Finally, Found an answer for the problem...
There are 2 major translation services available one is paid and one is free.
Sharing the Solution:
I used java-google-translate-text-to-speech instead of Google Translate API v2 Java.
About java-google-translate-text-to-speech
The Api is unofficial with the main features of Google Translate in Java.
It also provide text to speech api. If you want to translate the text "Hello!" in Hindi just write:
Translator translate = Translator.getInstance();
String text = translate.translate("Hello!", Language.ENGLISH, Language.HINDI);
System.out.println(text); // "नमस्ते"
It's free!
One Important Point: Google Translate API v2 is now available as a paid service. Google Translate API is available as a paid service. See the Pricing and FAQ pages on google for details.
BUT, java-google-translate-text-to-speech is FREE! There is one issue with the API Since google updated its code. The custom Version can be downloaded from this direct link.
Thanks!!! Now you can Close the Thread :)
