i have array of json elements string, problem how convert them , object array using gson. found methods on site non of them seem work string.

["2": {"id": 2, "name": "cannonball", "sp": 5, "overall_average": 194, "buy_average": 193, "members": true, "sell_average": 193},   "6": {"id": 6, "name": "cannon base", "sp": 187500, "overall_average": 188110, "buy_average": 184547, "members": true, "sell_average": 185735},   "12289": {"id": 12289, "name": "mithril platelegs (t)", "sp": 2600, "overall_average": 0, "buy_average": 3000, "members": false, "sell_average": 3000},   "8": {"id": 8, "name": "cannon stand", "sp": 187500, "overall_average": 198445, "buy_average": 189001, "members": true, "sell_average": 190889},   "10": {"id": 10, "name": "cannon barrels", "sp": 187500, "overall_average": 194418, "buy_average": 185164, "members": true, "sell_average": 185935},   "12": {"id": 12, "name": "cannon furnace", "sp": 187500, "overall_average": 188000, "buy_average": 186524, "members": true, "sell_average": 186637},   "4099": {"id": 4099, "name": "mystic hat (dark)", "sp": 15000, "overall_average": 9758, "buy_average": 9229, "members": true, "sell_average": 9528}] 

i need convert data java object.

public class osbuddyitem {     private final int id;     private final string name;     private final int sellprice;     private final int buyprice;     private final int averageprice;     private final int storeprice;     private final boolean members;      public osbuddyitem(int id, string name, int sellprice, int buyprice, int averageprice, int storeprice, boolean members){          this.id = id;         this.name = name;         this.sellprice = sellprice;         this.buyprice = buyprice;         this.averageprice = averageprice;         this.storeprice = storeprice;         this.members = members;     }      public int getid() {         return id;     }      public string getname() {         return name;     }      public int getsellprice() {         return sellprice;     }      public int getbuyprice() {         return buyprice;     }      public int getaverageprice() {         return averageprice;     }      public int getstoreprice() {         return storeprice;     }      public boolean ismembers() {         return members;     } } 

this tried:

gson gson = new gson();         jsonparser parser = new jsonparser();         jsonelement tradeelement = parser.parse(data);         jsonarray itemelements = tradeelement.getasjsonarray();         osbuddyitem[] items = gson.fromjson(itemelements,osbuddyitem[].class);          for(osbuddyitem item : items){             system.out.println(item.getname());         } 

can please tell me how convert string using gson?

your json string not valid.you can validate json string [http://jsoneditoronline.org/][1]

suppose if json string in form :-

[{"1": {"id": 2, "name": "cannonball", "sp": 5, "overall_average": 194, "buy_average": 193, "members": true, "sell_average": 193}}] 

suppose model name example.then model of json :-

package com.example;

import com.google.gson.annotations.serializedname;

public class example {

@serializedname("id")  private integer id; @serializedname("name")  private string name; @serializedname("sp")  private integer sp; @serializedname("overall_average")  private integer overallaverage; @serializedname("buy_average")  private integer buyaverage; @serializedname("members")  private boolean members; @serializedname("sell_average")  private integer sellaverage;  public integer getid() {     return id; }  public void setid(integer id) {     this.id = id; }  public string getname() {     return name; }  public void setname(string name) {     this.name = name; }  public integer getsp() {     return sp; }  public void setsp(integer sp) {     this.sp = sp; }  public integer getoverallaverage() {     return overallaverage; }  public void setoverallaverage(integer overallaverage) {     this.overallaverage = overallaverage; }  public integer getbuyaverage() {     return buyaverage; }  public void setbuyaverage(integer buyaverage) {     this.buyaverage = buyaverage; }  public boolean getmembers() {     return members; }  public void setmembers(boolean members) {     this.members = members; }  public integer getsellaverage() {     return sellaverage; }  public void setsellaverage(integer sellaverage) {     this.sellaverage = sellaverage; } 

}

and using gson ,you can convert below. [note :typetoken class used load json string custom object]

 list<example> mylist = new gson().fromjson(br, new typetoken<list<jsonlog>>(){}.gettype());
