java - Resource Loading: How to determine if it's a directory -

-

currently use solution load resources:

url url = myclass.class.getclassloader().getresource("documents/"+path); if(url == null)     throw new filenotfoundexception();  bufferedreader reader = new bufferedreader(     new inputstreamreader(url.openstream()));

sadly can't control whether path file or directory. there way can determine if denoted path directory? i'm looking solution independent resource loaded (in other words: file.isfile won't work when loading resource jar).

i use code grab names of text files jar.

public string[] getfiles() throws ioexception {     arraylist<string> list = new arraylist<string>();     list<jarentry> ents = new arraylist<jarentry>();     enumeration<jarentry> e = null;      url jarp = getlocation();     if (jarp != null) {         jar = jarp.getprotocol().equalsignorecase("jar") ? jarp : new url("jar:" + jarp.tostring() + "!/");         jarfile jarf = null;         try {             jarf = accesscontroller.doprivileged(                     new privilegedexceptionaction<jarfile>() {                          @override                         public jarfile run() throws exception {                             jarurlconnection conn = (jarurlconnection) jar.openconnection();                             conn.setusecaches(false);                             return conn.getjarfile();                         }                     });         } catch (privilegedactionexception ex) {             logger.getlogger(licenseloader.class.getname()).log(level.severe, null, ex);         }         e = jarf.entries();         while (e.hasmoreelements()) {             jarentry je = e.nextelement();             if (!je.isdirectory()) {                 ents.add(je);             }         }         (jarentry ent : ents) {             if ((ent.getname().startswith(pathname)) && (ent.getname().endswith(".txt"))) {                 string name = ent.getname().replace(pathname, "");                 list.add(name);             }         }     }     return list.toarray(new string[list.size()]); }

c# - Copy ObservableCollection to another ObservableCollection -

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...
