java - Is it normal that sampling tweets using TwitterStream as in Twitter4J code example, I get just mainly question marks as user name and status? -

i used code in section "code example" in twitter4j:

public static void main(string[] args) throws twitterexception, ioexception{     statuslistener listener = new statuslistener(){         public void onstatus(status status) {             system.out.println(status.getuser().getname() + " : " + status.gettext());         }         public void ondeletionnotice(statusdeletionnotice statusdeletionnotice) {}         public void ontracklimitationnotice(int numberoflimitedstatuses) {}         public void onexception(exception ex) {             ex.printstacktrace();         }     };     twitterstream twitterstream = new twitterstreamfactory().getinstance();     twitterstream.addlistener(listener);     // sample() method internally creates thread manipulates twitterstream , calls these adequate listener methods continuously.     twitterstream.sample(); } 

as can see, there's println in code above, inside method "onstatus". following photo shows code. normal?

question marks...question marks everywhere

indeed, i filter statuses user hasn't got question mark in user name, got nothing. moreover, should filter users location public. regards ask difference between:

user.isgeoenabled() 

and

user.getlocation() != "" 

the responses utf-8 encoded https://dev.twitter.com/tags/utf-8

if @ of accounts in output include non-western european characters https://twitter.com/tomokichi_koyo. these breaking output.

try writing file instead , opening utf-8 aware editor. there various answers setting java , os default utf-8 need specific combination https://stackoverflow.com/search?q=windows+console+java+utf-8
