Is a Locale considered complete only if

Example: In the class Currency there is a static method getInstance(Locale locale). However If I write something like:

Currency currency = Currency.getInstance(Locale.forLanguageTag("it"));

It gives an exception (IllegalArgument..)

On the other hand:

Currency currency = Currency.getInstance(Locale.forLanguageTag("it-IT"));

Compiles without problem.

Can we safely say that without the country code the locale it's incomplete?

Note that specifying the only language it's a valid option to construct a Locale in some circumstances es:

Locale localize = Locale.forLanguageTag("it");
    System.out.println(localize.getDisplayName());
