Java JSON deserialize String with property names as field names -

i receiving api json that:

{   "channel":"masta",   "starttime":1427673600000,   "endtime":1427760000000,   "totaluniques":1,   "totalviewtime":1927,   "totalviews":13,   "totalcountries":1,   "countries":{     "us":{       "uniques":1,       "views":13,       "viewtime":1927     }   } } 

now want deserialize class, class(stats) have fields channel, starttime , on. how handle countries property?

i thought making class countries not sure cause it's have "us" property name. not "country": "us". , what's more has own parameters. how deserialize it?

mostly using objectmapper object.readvalue(jsonstring) don't know how handle 'countries'. in example 1 country 'us' can more.

declare country class:

public class country {     private int uniques;     private int views;     private int viewtime;      public int getuniques() {         return uniques;     }      public void setuniques(int uniques) {         this.uniques = uniques;     }      public int getviews() {         return views;     }      public void setviews(int views) {         this.views = views;     }      public int getviewtime() {         return viewtime;     }      public void setviewtime(int viewtime) {         this.viewtime = viewtime;     } } 

in stats class should declare countries map of country objects:

public class stats {     private string channel;    private long starttime;    private long endtime;        private int totaluniques;    private int totalviewtime;    private int totalviews;    private int totalcountries;     ...     private map<string, country> countries;     public map<string, country> getcountries() {        return countries;    }     public void setcountries(map<string, country> countries) {        this.countries = countries;    }  } 

now can deserialize object:

objectmapper mapper = new objectmapper(); stats stats = mapper.readvalue(jsonstring, stats.class); 

after deserialization stack object map 1 country object key "us".
