Try this website , where you can enter your JSON string and it generates the Java Class for you.

Edit:

Try this modified JSON with the website and it should generate your Java models:

{
   "channel":{
      "title":"jeux"
   },
   "classification":{
      "day":{
         "id":"3175",
         "accr":"J5",
         "type":"0",
         "title":"xxxxxxxx",
         "start":"2016-09-17",
         "finish":"2016-09-18",
         "poolid":"36",
         "pool_name":null,
         "rankings":{
            "1":{
               "cal":{
                  "id":"12",
                  "name":"yyyyy",
