JSON Object Exception - json

Question

I am writing a web service-REST.
I am receiving a text_plain format.
Example of my data:
{"data_log":
{
"methodClass": [{"methodName": 1, "methodStatus": "1"},
{"methodName": 2, "methodStatus": "1"}]
}
}
In my Restful Webservice, I try to read the data, but I got error 500 Internal Server Error-JSON Object not found.
public int adaptiveAuth(String objDataLog){
logWriter("objDataLog:"+objDataLog);
JSONObject obj = new JSONObject(objDataLog);
JSONArray methodClassObj=(JSONArray)obj.get("methodClass");
if (methodClassObj != null) {
JSONObject methodObj;
String entrymethodName, entrymethodStatus;
for (Object o : methodClassObj) {
methodObj = (JSONObject) o;
entrymethodName = String.valueOf(methodObj.get("methodName"));
entrymethodStatus = String.valueOf(methodObj.get("methodStatus"));
logWriter("entrymethodName:"+entrymethodName);
logWriter("entrymethodStatus:"+entrymethodStatus);
}
}
}
I already tried to use the below code, but it still give me the error.
String methodClass= obj.getJSONObject("data_log").getString("methodClass");
I'm expecting to put the current data into an 2 dimension array which it would be like this:
[1,1],[2,1]
Anyone could give me some suggestion on how to solve this issue?

Answer 1

**Try this code for parsing json data**
ArrayList<HashMap<String, String>> list;
JSONObject jsonObj = new JSONObject(jsonStr);
// Getting JSON Array node
JSONArray b= jsonObj.getJSONArray("methodClass");
// looping through All data
for (int i = 0; i < b.length(); i++) {
JSONObject c = b.getJSONObject(i);
String entrymethodName = c.getJSONObject("methodClass").getString("methodName");
String entrymethodStatus = c.getJSONObject("methodClass").getString("methodStatus");
// tmp hash map for storing values
HashMap<String, String> co = new HashMap<>();
// adding each child node to HashMap key => value
co.put(entrymethodName, entrymethodStatus );
// adding co to list
list.add(co);

I changed by String to this format:
{ "methodSet": [
{
"methodName": 1,
"methodStatus": "1"
},
{
"methodName": 2,
"methodStatus": "1"
}
]
}
and for the code :
ArrayList<String> listMethod = new ArrayList<String>();
JSONArray arr=(JSONArray)obj.get("methodClass");
if (arr != null) {
JSONObject objMethod;
String MethodName, MethodStatus;
for (Object o : arr) {
objMethod = (JSONObject) o;
MethodName = String.valueOf(objMethod.get("methodName"));
MethodStatus = String.valueOf(objMethod.get("methodStatus"));
int resultMethodName = Integer.parseInt(MethodName);
int resultMethodStatus = Integer.parseInt(MethodStatus);
logWriter("MethodStatus"+resultMethodName);
logWriter("MethodName"+resultMethodStatus);
listMethod.add("(" + MethodName + "," + MethodStatus + ")");
logWriter("listMethod is : "+listMethod);
}
}
