Say you want to create a JSON as shown below

{"subitem":
 [{"rate":"123",
   "baseitem":"148",
   "item":"HIJ",
   "section":"pub",
   "imagename":"pic.png"
 }],

 "hoteltables":
 [{"tableno":"123",
   "status":"active",
   "section":"pub",
   "custid":"12"
 }],

 "mainiteam":
 [{"status":"available",

The java code for creating the above JSON is as given below

JSONArray obj = new JSONArray();
JSONObject jsonobj=new JSONObject();

HashMap rows=new HashMap();
rows.put("tableno","123");
rows.put("status","active");
rows.put("section","pub");
rows.put("custid","12");
obj.put(rows);

jsonobj.put("hoteltables", obj);

obj = new JSONArray();

rows=new HashMap();
rows.put("itemid","12");
rows.put("item","ABC");
rows.put("status","available");
rows.put("section","pub");
rows.put("imagename","XYZ");
obj.put(rows);

jsonobj.put("mainiteam", obj);

obj = new JSONArray();
rows=new HashMap();
rows.put("baseitem","148");
rows.put("item","HIJ");
rows.put("rate","123");
rows.put("section","pub");
rows.put("imagename","pic.png");
obj.put(rows);

jsonobj.put("subitem", obj);

System.out.println(jsonobj.toString());
