                "brief":"test 1 sevice brief,
                "classSize":"1",

        },
        "1523":{
            "service":{
                "title":"test 2 service",
                "defaultDuration":"90",
                "brief":"test 2 brief.",
                "classSize":"1",
            }
        },
        "organisation":{
        "title":"Second orginization",
        "url":"http:\/\/test.com\/main2",
        "address":"18 Street",
        "suburb":"South ",
        "postcode":"1241",
        "state":"Teststate",
        "country":"US"
    }
}

}

I would just parse it normally, then use the 'for ( i in o )' loops to get the data out, and put it in an array. This way, you don't need to write a custom parse, just custom logic. Much easier, I would think. — Horus

i parse it using json object but after that iteration the positions are not as it. see my first question stackoverflow.com/questions/7051785/… — mastermind

Your real problem is that the JSON you are parsing is NOT an array. It is an object (a dictionary) whose keys are numbers.

If you really need it to be an array, you will need to parse it as a JsonObject and build the array yourself by iterating over the object's keys, etcetera.

I would also add that this is not a good idea, if the sample you have provided is indicative. The resulting array will be sparse; i.e. there will be lots of "holes" where there is no entry for a given index. This could waste a lot memory ... depending on the actual keys.

then how can i parse it. becoz using iterator it keys are changed not in order as in string.

Parse it as an object, then iterate through the keys, transform each key into an Integer, and place each key with its associated value in a TreeMap. The keys will then be sorted in ascending order.
