Look at your code. you need to change

        List<IdentifiedLanguage> languages = lt.identify("this is a test");

to be

        List< IdentifiableLanguage > languages = lt.identify("this is a test");

[shikida]

hey, that's not right

in 2.9.0, lt.identify("this is a test") resolves to List[IdentifiedLanguage], not List[IdentifiableLanguage]

try to download the jar and check yourself

pls re-open

it seems that what happens is

    List<IdentifiedLanguage> languages = lt.identify("this is a test");
    for(IdentifiableLanguage l:languages){
        System.out.println(l.toString());
    }

but IdentifiableLanguage is the superclass. It's not intuitive.

and also, the method can't recognize the language, which is English in this case

see

[leoks@oc7612866413 ~]$ curl -u "5e778314-2875-4ebd-8b1f-9ed6ae98fd07":"****"
"https://gateway.watsonplatform.net/language-translation/api/v2/identify?text=this+is+a+test"
en

while this method from the sdk returns a list of all available languages instead
