Design pattern for different method signiture

I am new to design pattern.

My question is what pattern do I use in below case?

interface UserExtractorService {
    String getUser(XXXX);
    default validate(File file);
}

class AExtractorService {
    public String getUser(String url) {
           validate(downloadfromWeb(url));
       return getFromWeb(url);
    }
}

class BExtractorService {
    public String getUser(File) {
           validate(file);
           parsingFromFile(File);
       return parsingFromFile(File);
    }
}

class Client {

    public void GetUsers(String key) {
         userExtractorService.getUser(key);
    }

    public void GetUsers(File file) {
         userExtractorService.getUser(file);
    }
}

I want to group AExtractor and BExtractor, because it need operate similar behavior.
