JSON字符串通常包含了多个属性和值,我们可以通过解析后的JSON对象来获取指定属性的值。 StringjsonString="{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";JSONObjectjson=newJSONObject(jsonString);Stringname=json.getString("name");intage=json.getInt("age");Stringcity=json.getStrin...
// 可以通过map.get(key)获取json中的具体字段值，例如：String name = (String) map.get("name")...
至此,我们已经成功地实现了JSON.parse方法。现在,person对象中的属性值就是从JSON字符串中解析出的值。 下面是一个完整的示例代码: importcom.fasterxml.jackson.databind.ObjectMapper;publicclassMain{publicstaticvoidmain(String[]args){StringjsonString="{\"name\":\"John\", \"age\":30, \"city\":\"New...
