json - Getting the error code message in twitter api request (java) -

-

i'm trying use twitter api in following way:

string urladd = "https://api.twitter.com/1/following/ids.json?user_id=1000123"; url url = new url(urladd); urlconnection urlconnection = url.openconnection(); bufferedreader in = new bufferedreader(new inputstreamreader(urlconnection.getinputstream()));

getinputstream input stream throws ioexception, happens because i've reached request limit. want able distinghuish between request limit error , other errors. twitter returns error message in json format, can't read because of thrown exception.

any ideas on how can fetch error message?

i found way it:

string urladd = "https://api.twitter.com/1/following/ids.json?user_id=1000123"; url url = new url(urladd); urlconnection urlconnection = url.openconnection(); httpurlconnection httpconn = (httpurlconnection)urlconnection; inputstream is; if (httpconn.getresponsecode() >= 400) {     = httpconn.geterrorstream(); } else {     = httpconn.getinputstream(); } bufferedreader in = new bufferedreader(new inputstreamreader(is));

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
