Answer 1

You may use it like below, you need to use push command to push an object inside an array.

var myObj = {
   "cluster":[
      {
         "path":"home/Nik",
         "password":"welcome",
         "isQueen":"true",
         "host":"192.168.11.248",
         "isQueenWorker":"true",
         "user":"Nik"
      }
   ]
};
var x = {
   "path":"home\/Nik",
   "password":"welcome",
   "isQueen":"true",
   "host":"192.168.11.248",
   "isQueenWorker":"true",
   "user":"Nik"
};
alert(JSON.stringify(myObj))
var newArr = myObj.cluster; 
newArr.push(x) //pushing object x in newArr. similarly you can add multiple objects in to it
var myJSON = JSON.stringify(newArr);
alert(myJSON)

Answer 2

you can directly append it

eg. first json

{"cluster":[{"path":"home/Nik","password":"welcome","isQueen":"true","host":"192.168.11.248","isQueenWorker":"true","user":"Nik"}]}

int i= cluster.length();

cluster[i]={"path":"home/Nik","password":"welcome","isQueen":"true","host":"192.168.11.248","isQueenWorker":"true","user":"Nik"}
