Is it possible to collect offline http api translator?

Question

Java

The result should be a working offline translator.
That is, you need an http API similar to what Google Translate and Yandex Translator have.
Found several options:

1. Install Microsoft Translator on Windows, download dictionaries, and somehow transfer requests for translation via http
   
2. Apertium , this option is closer to reality, but it's not clear how to set everything up...
   
3. Apache Joshua
   
4. Promt , actually this is the ideal option, but it is very expensive
   
5. Install Android on a PC, and there is already Google Translate, only again there will be a question of transmitting http requests
   

You need to translate entire sentences, not just individual words.
Maybe there is some kind of console utility. Or maybe there is something under linux.
Which of the above options is better to look for more information?
