Hi. I wanna count number of objects in array. For example: jsonObj["array"] is object that store another objects. I can access them by jsonObj["array"][0]["something"], jsonObj["array"][1]["something"], jsonObj["array"][2]["something"], and so on. So how do I count number of objects in jsonObj["array"]?

Thank you. :)

Size () - is not length of Array, it's just count of all elements in whole array
