Objects can be nested inside other objects. Each nested object must have a unique access path. The same field name can occur in nested objects in the same document. However, the full access name must still be unique. Examples To access nested fields, concatenate the field names with a "."...
Here we have a JSON object that contains nested JSON objects. This example demonstrates how to access the contents of the nested objects. { "name": "donut", "image": { "fname": "donut.jpg", "w": 200, "h": 200 }, "thumbnail": { "fname": "donutThumb.jpg", "w": 32, "h"...
String firstName = object.getString("firstName"); This map object provides read-only access to the JSON object data, and attempts to modify the map, whether direct or via its collection views, result in anUnsupportedOperationException.
jsonObject.put("key1", "value1"); jsonObject.put("key2", 123); jsonObject.put("key3", true); 如果需要将复杂的数据结构放入JSONObject中,可以使用嵌套的JSONObject或JSONArray。例如,在Java中可以使用以下代码将嵌套的JSONObject放入父JSONObject中: 代码语言:txt 复制 JSONObject nestedObject = new ...
