java - Unable to build this Complex JSON Structure -

-

i have inter-related maps representing below data .

{          "soft drinks": {             "tin": [                 {                     "lean apple": [                         {                             "name": "1 litre"                         },                         {                             "name": "2 litre"                         }                     ]                 },                 {                     "clear": [                         {                             "name": "7 litre"                         },                         {                             "name": "10 litre"                         }                     ]                 }             ],             "bottled": [              ]         }     }

this code representing above json data in form of java code

package test;

import java.util.linkedhashmap; import java.util.linkedlist; import java.util.map;  import org.json.jsonexception; import org.json.jsonobject;  public class post {      public static void main(string args[]) throws jsonexception     {         linkedlist<string> fortinitemslist = new linkedlist<string>();         linkedlist<string> forbottleitemslist = new linkedlist<string>();          jsonobject jsonobj = new jsonobject();           map<string,linkedlist<string>> categoryitemsmap = new linkedhashmap<string,linkedlist<string>>();          fortinitemslist.add("lean apple");         fortinitemslist.add("clear");           forbottleitemslist.add("lemon");         forbottleitemslist.add("clear");            categoryitemsmap.put("tin", fortinitemslist);         categoryitemsmap.put("bottled", forbottleitemslist);          // completion of categories.           map<string,linkedlist<string>> subcategory = new linkedhashmap<string,linkedlist<string>>();          linkedlist<string> forlemonitems = new linkedlist<string>();         forlemonitems.add("1 litre");         forlemonitems.add("2 litre");          subcategory.put("lemon", forlemonitems);            linkedlist<string> forclearitems = new linkedlist<string>();         forclearitems.add("7 litre");         forclearitems.add("10 litre");          subcategory.put("clear", forclearitems);           (map.entry<string, linkedlist<string>> entry : categoryitemsmap.entryset())         {             string key = entry.getkey();              linkedlist<string> list = entry.getvalue();              for(string value : list)             {                 system.out.println(key+"\t"+value);             }              //jsonobj.put(entry, arg1);          }       }  }
