json - Android - YouTube API get videoId from video list -


i want videoid in (items:[ id:{ ) shows org.json.jsonexception: no value videoid. there wrong code here?

items: [ {     kind: "youtube#searchresult",     etag: ""etag"",     id: {         kind: "youtube#video",         videoid: "nsvttbhym2e"     },     snippet: {         publishedat: "publishedat",         channelid: "channelid",         title: "title",         description: description",     thumbnails: {         default: {             url: "thumbnail url",             width: 120,             height: 90         },         medium: {             url: "thumbnail url",             width: 320,             height: 180         },         high: {             url: "thumbnail url",             width: 480,             height: 360         }     },     channeltitle: "channeltitle",     livebroadcastcontent: "none"     } },

this part of source code video id video list 

jsonarray items = jsonobject.getjsonarray("items"); (int = 0; < items.length(); i++) {     jsonobject json_data = items.getjsonobject(i);     strvideoid = json_data.getjsonobject("id").getstring("videoid"); }

first of all, providing invalid json, take notice etag , description have invalid values.

assuming have valid json data, can retrieve list of video ids values using following method:

private list<string> getvideoids(final jsonobject jsonobject) {     final list<string> videoidlist = new arraylist<>();     if (null != jsonobject) {         try {             final jsonarray itemarray = jsonobject.getjsonarray("items");             final int itemcount = itemarray.length();             (int = 0; < itemcount; ++i) {                 final jsonobject item = itemarray.getjsonobject(i);                 final jsonobject id = item.getjsonobject("id");                 final string videoid = id.getstring("videoid");                 videoidlist.add(videoid);             }         } catch (final jsonexception e) {             e.printstacktrace();         }     }     return videoidlist; }

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
