Judgment of JSONArray and JSONObject

Judgment of JSONArray and JSONObject

Is the content of the JSON file an array or a simple substance? That

That's why I wrote it with a sudden idea like this. If the first character is [, it is judged to be JSONArray for the time being. Whether or not the string passes through the parser.

if(jsonStr.charAt(0) == '[') {
  //JSONArray
} else if(jsonStr.charAt(0) == '{') {
  //JSONObject
}

When I was looking for a smarter way, I found something like this

Object object = new JSONTokener(data).nextValue();
if (object instanceof JSONArray) {
  //JSONArray
} else if (object instanceof JSONObject) {
  //JSONObject
}

I think this is better

end
