提问by SaDeGH_F
Just a quick question:
只是一个简单的问题:
If I have a json object which contains "key/value"s like this:
如果我有一个包含“键/值”的 json 对象,如下所示:
"name":"value"
and I want to change the name parts to something else, what should I do? I don't want to remove and make it again.

Proper and compact implementation, given that jsonObject
is the json object you are referring to and it is an instance of JSONObject
:
正确和紧凑的实现,因为这jsonObject
是您所指的 json 对象,它是 的一个实例JSONObject
:
jsonObject.put("new name", jsonObject.remove("name"));

Create a new object with the new value
使用新值创建一个新对象
new JSONObject(jsonobject.toString().replace("\"name\":","\"newvalue\":");)
