The difference between Net.sf.json.JSONObject and Org.json.JSONObject

The difference between Net.sf.json.JSONObject and Org.json.JSONObject.

First, create a JSON object

String str = "{\" code\ ": \" 0000\ ", \" msg\ ": {\" availablebalance\ ": 31503079.02}}

Org.json.JSONObject:

Jsonobject json = new Jsonobject (str);

Net.sf.json.JSONObject:

Jsonobject JSON = Jsonobject.fromobject (str); Net.sf.json.jsonobject no new Jsonobject (String) Construction method

Second, parsing JSON

The first is the direct use of JSON objects. GetXXX (); method gets

Net.sf.json.JSONObject: No strict requirements gets the type of field that is the same as the type of getxxx ()

Org.json.JSONObject: The type of field to get must be the same as the type of getxxx ()

e.g.

Jsonobject msgobj = Json.getjsonobject ("msg");

String availablebalance = msgobj.getstring ("availablebalance");

If the org.json.JSONObject will be error, you can msgobj.getdouble ("Availablebalance"), and will not lose precision While Net.sf.json.JSONObject is correct, the accuracy is lost if string str = "{\" code\ ": \" 0000\ ", \" msg\ ": {\" availablebalance\ ": \" 31503079.02 \"}}";

There is no loss of precision.

The second JSON object transforms the entity object directly

public class Balancedto {
Private String availablebalance;
Public String getavailablebalance () {
return availablebalance;
}
public void Setavailablebalance (String availablebalance) {
This.availablebalance = availablebalance;
}
Public String toString () {

Return "Availablebalance" +availablebalance;
}


}
Org.json.JSONObject:

Balancedto alancedto = (balancedto) jsonobject. Stringtovalue (Msgobj);

This sentence compiles through, but the run will error because the type of availablebalance in the Balancedto class does not agree with the "availablebalance" type in JSON

Net.sf.json.JSONObject:

String msg = json.getstring ("msg");
Balancedto alancedto = (balancedto) jsonobject. Tobean (
MSG, new Balancedto (). GetClass ());

Third, get the array from the JSON

Jsonarray Subarray = Json.getjsonarray ("msg");

Net.sf.json.JSONObject:

int leng = Subarray. Size ();

Org.json.JSONObject:

int leng = Subarray. Length ();

There are other differences can compare two API documentation, if there is an error, please ask, you can send e-mail to [email protected]
