                                            "Name": "xddxxcc",
                                        },
                                        {
                                            "Id": "20",

                                        },
                                        {
                                            "Id": "23",
                                            "Name": "cdaca",

                                            "Children": []
                                        },
                                        {
                                            "Id": "28",
                                            "Name": "assa",
                                            "Children": [ ]
                                        }
                                    ]
                                },

                        {
                            "Id": "15",
                            "Name": "fdcds"
                            "Children": []
                        }]}]}]

I have taken Model class Like below.

class Model1{
String id;
String Name;
ArrayList<Children>Children=new ArrayList<>();
//Getters and setters
}

and Children.class File was

class Children{
 String id;
    String Name;
    ArrayList<Children>Children=new ArrayList<>();
    //Getters and setters
}

Please Some one help me. Thanks In Advance

you can use 1 class for all of the objects, since your 2 classes are equal. But what is the problem exactly? Why you can't do what you want? — Vladyslav Matviienko, Aug 03 '17 at 06:52

Your JSON is invalid. Proper below:

[  
   {  
      "Id":"-1",
      "Name":"name1",
      "Children":[  
         {  
            "Id":"2",
            "Name":"name2",
            "Children":[  
               {  
                  "Id":"3",
                  "Name":"name3",
                  "Children":[  
                     {  
                        "Id":"15",
                        "Name":"name222",
                        "Children":[  
                           {  
                              "Id":"16",
                              "Name":"xddxxcc",
                              "Children":[  

                              ]
                           },
                           {  
                              "Id":"20",
                              "Name":"sdd",
                              "Children":[  

                              ]
                           },
                           {  
                              "Id":"23",
                              "Name":"cdaca",
                              "Children":[  

                              ]
                           },
                           {  
                              "Id":"28",
                              "Name":"assa",
                              "Children":[  

                              ]
                           }
                        ]
                     },
                     {  
                        "Id":"15",
                        "Name":"fdcds",
                        "Children":[  

                        ]
                     }
                  ]
               }
            ]
         }
      ]
   }
]

This is your model:

public class Child
{
    public string Id { get; set; }
    public string Name { get; set; }
    public Child[] Children { get; set; }
}

And for parsing json into your model use: (I assume you're using java) (reference)

Jackson

import com.fasterxml.jackson.databind.ObjectMapper;
ObjectMapper mapper = new ObjectMapper();
Child[] myObjects = mapper.readValue(json, Child[].class)

GSON

Gson gson = new Gson();
Child[] myObjects = gson.fromJson(json, Child[].class);
