is there chance files in folders in json using google drive api, simple sending method? yes, possible. can use files.list . corresponding request, returns files default. get https://www.googleapis.com/drive/v2/files take closer here . there online demo test it. the java code request this: private static list<file> retrieveallfiles(drive service) throws ioexception { list<file> result = new arraylist<file>(); files.list request = service.files().list(); { try { filelist files = request.execute(); result.addall(files.getitems()); request.setpagetoken(files.getnextpagetoken()); } catch (ioexception e) { system.out.println("an error occurred: " + e); request.setpagetoken(null); } } while (request.getpagetoken() != null && request.getpagetoken().length() > 0); return result; }

there list of string this {'123', '234', '345', '123c', '456', '234c'} and task create list<tuple<string><string>> , fill every tuple first value 'x' , second value 'xc' example tuple<123,123c> , if there not pair ending 'c' char, put second value null, in tuple tuple<345,null>. there way linq?. you try this: var result = list.groupby(word => !word.endswith('c')) .select(gr => tuple.create(gr.key, gr.firstordefault(i=>i.contains(gr.key)))); essentially, group list elements based on if word ends caracter 'c'. have sequence of keys, words doesn't end character 'c' , associated sequence each of keys words end 'c'. project result in sequence of tuples first element key of gropu , second element corresponding value ends 'c' if exists @ or null if doesn't exists.

what problems occur declaring variable inside if condition twice? i understand not best way of doing it! know can declare variable outside if condition. i'm not looking solution! i'm not looking how can declare variables. want understand why bad approach declare variable inside if-condition block. /* yes know can have condition instead of condition === true, simplicity */ if(condition === true){ var stuckups = "over 9000"; }else if(condition === false){ var stuckups = "nothing"; } alert(stuckups) /* yes can access outside if condition!*/ why bad habit if 1 condition executed, means variable declare once anyway. real problems it? you correct it's not wrong, specified in ecmascript, hoisted top of nearest function definition. this lead problems when having large codebase , "hard" find.
