如何将json数组转换为json对象

[
  {
    "name": "John",
    "age": 30,
    "city": "New York"
  },
  {
    "name": "Jane",
    "age": 25,
    "city": "San Francisco"
  }
]

var jsonArray = '[{"name":"John","age":30,"city":"New York"},{"name":"Jane","age":25,"city":"San Francisco"}]';
var jsonObject = JSON.parse(jsonArray);
console.log(jsonObject);

import json

jsonArray = '[{"name":"John","age":30,"city":"New York"},{"name":"Jane","age":25,"city":"San Francisco"}]'
jsonObject = json.loads(jsonArray)
print(jsonObject)

import org.json.JSONArray;
import org.json.JSONObject;

String jsonArray = "[{\"name\":\"John\",\"age\":30,\"city\":\"New York\"},{\"name\":\"Jane\",\"age\":25,\"city\":\"San Francisco\"}]";
JSONArray jsonArrayObj = new JSONArray(jsonArray);
JSONObject jsonObject = jsonArrayObj.getJSONObject(0);
System.out.println(jsonObject);
