{ "801345": [{     "type": "football",     "name": "a",     "id": "1" }, {     "type": "football",     "name": "b",     "id": "2" },{     "type": "cricket",     "name": "c",     "id": "3" }, {     "type": "volley",     "name": "d",     "id": "4" }]

}

{ "910358": [{     "type": "football",     "name": "a",     "id": "1" }, {     "type": "football",     "name": "b",     "id": "2" },{     "type": "cricket",     "name": "c",     "id": "3" }, {     "type": "volley",     "name": "d",     "id": "4" }]

}

i created method parsing type json. try this

    private arraylist<teams> teamsjsonparsing(string json) throws jsonexception {            /*json="{\n" +                 "\"801345\": [{\n" +                 "    \"type\": \"football\",\n" +                 "    \"name\": \"a\",\n" +                 "    \"id\": \"1\"\n" +                 "}, {\n" +                 "    \"type\": \"football\",\n" +                 "    \"name\": \"b\",\n" +                 "    \"id\": \"2\"\n" +                 "},{\n" +                 "    \"type\": \"cricket\",\n" +                 "    \"name\": \"c\",\n" +                 "    \"id\": \"3\"\n" +                 "}, {\n" +                 "    \"type\": \"volley\",\n" +                 "    \"name\": \"d\",\n" +                 "    \"id\": \"4\"\n" +                 "}]\n" +                 ",\n" +                 "\n" +                 "\n" +                 "\"910358\": [{\n" +                 "    \"type\": \"football\",\n" +                 "    \"name\": \"a\",\n" +                 "    \"id\": \"1\"\n" +                 "}, {\n" +                 "    \"type\": \"football\",\n" +                 "    \"name\": \"b\",\n" +                 "    \"id\": \"2\"\n" +                 "},{\n" +                 "    \"type\": \"cricket\",\n" +                 "    \"name\": \"c\",\n" +                 "    \"id\": \"3\"\n" +                 "}, {\n" +                 "    \"type\": \"volley\",\n" +                 "    \"name\": \"d\",\n" +                 "    \"id\": \"4\"\n" +                 "}]\n" +                 "}"; */           jsonobject jsonobject=new jsonobject(json);         iterator itr =jsonobject.keys();         gson gson=new gson();         arraylist<teams> teamsarraylist=new arraylist<>();         while(itr.hasnext()) {             object element = itr.next();             log.e("iterator",jsonobject.getjsonarray(element.tostring()).tostring());             teams teams=new teams();             teams.setteamname(element.tostring());             arraylist<team> teamarraylist=new arraylist<>();             jsonarray jsonarray=jsonobject.getjsonarray(element.tostring());           (int i=0;i<jsonarray.length();i++){               team team=gson.fromjson(jsonarray.getjsonobject(i).tostring(),team.class);               teamarraylist.add(team);           }           teams.setteam(teamarraylist);             teamsarraylist.add(teams);          }         return teamsarraylist;     }

example usage

 try {         arraylist<teams> teamses= teamsjsonparsing(json);         log.e("team",teamses.size()+"");     } catch (jsonexception e) {         e.printstacktrace();     }

your model classes are

 public class team {      @serializedname("type")     @expose     private string type;     @serializedname("name")     @expose     private string name;     @serializedname("id")     @expose     private string id;      public string gettype() {         return type;     }      public void settype(string type) {         this.type = type;     }      public string getname() {         return name;     }      public void setname(string name) {         this.name = name;     }      public string getid() {         return id;     }      public void setid(string id) {         this.id = id;     }  }  public class teams {     string teamname ;      public string getteamname() {         return teamname;     }      public void setteamname(string teamname) {         this.teamname = teamname;     }      private list<team> team = null;      public list<team> getteam() {         return team;     }      public void setteam(list<team> team) {         this.team = team;     }  }

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
