Android Studio: Locale.getDefault().getLanguage() not working

Question

I am programming a small app with a multi language feature.

But when I'm going to check the default language, it wont work. Does anyone know why?

Code:

String Lang = Locale.getDefault().getLanguage();
    if(Lang == "de") {
        Log.i("de", "de");
    }
    else if(Lang == "fr") {
        Log.i("fr", "fr");
    }
    else {
        Log.i("en", "en");
    }

When I'm using the Log.i to show the String ,,Lang", it shows de. But when it runs, it shows en — KainAlive, Jan 23 '18 at 13:11
how exactly it doesn;t work? What is the expected and actual result? — Vladyslav Matviienko, Jan 23 '18 at 13:12
ok, you can't compare strings in Java using `==`. Use `.equals` — Vladyslav Matviienko, Jan 23 '18 at 13:13

first you're must compare string using equals method , but in your case I will use different approach

Locale local = Locale.getDefault();
if (locale.getLanguage().equals(new Locale("de").getLanguage())){ 
   Log.i("de", "de");
}
else if (locale.getLanguage().equals(new Locale("fr").getLanguage())){ 
   Log.i("fr", "fr");
}
else { 
   Log.i("en", "en");
}
