This is the JSON Response I received from OpenWeatherMap:
{
"coord": {

},

},
"id": 1275817,
"name": "Bhubaneswar",
"cod": 200
}
While I am able to use Weather by using this code below but unable to convert main to array. Is there anyway I can convert the bolded response to array or String.
JSONObject jsonObject = new JSONObject(result);
String weatherInfo = jsonObject.getString("weather");
JSONArray arr = new JSONArray(weatherInfo);
for(int i=0;i<arr.length();i++)
{
JSONObject jsonPart = arr.getJSONObject(i);
String main = jsonPart.getString("main");
String description =jsonPart.getString("description");
if(main !="" && description !="")
{
message += main + " : " + description + "\r\n";
}
}
The suggestion is, don't parse the JSON by hand. Use third party library like Gson to parse the JSON. This way you won't run into any typo errors and let the library handle the parsing for you.
Paste your json string to this website, and generate your pojo. Use the Gson to parse your string and bind to generated pojo.

This is my sample Json
{
"State": {
"version": "1",
"SName": "Test",
"shippingDetails": {
"Address1": "AP",
"ZipCode": "1236"
},
"Directions": {
"routes": [
{
"taxAmount": "0.0",
"Quantity": "5",
"bounds": {
"SerialVersion": [
{
"text": "1.7 km",
"value": "1729",
"time": "02633"
},
{
"text": "1.9 km",
"value": "1829",
"time": "02353"
},
{
"text": "17 km",
"value": "1059",
"time": "02133"
}
]
}
}
]
}
}
}
I want to update SName, ZipCode,taxAmount,Quantity, and text[1] values
are there any way to do this. I am taking JSON in a file and update tags are taking into HashMap
JSONObject jsonObject = new JSONObject("Your_JSON_String");
JSONObject jsonObjectForState = jsonObject.getJSONObject(“State”);
jsonObjectForState.put("Sname", "New_Value_Here");
put(...) will replace the current value with new value. Similarly, you can update the other values. Once you are done, you can convert it back using:
jsonObject.toString();
And write it back to the file.

This is tree represented in Json. But the keys for nested nodes keep changing.
For example "ROOT, nsubj, xcomp" ... etc.
How do I convert above json code to Java Object using gson.
Above response is from syntaxnet Parsey_Mcparseface api I'm trying to use.
Thanks in advance.
Gson has a method Gson#fromJson. For example, this is a code to read a simple String object.
Gson gson = new Gson();
String str = gson.fromJson("\"hello\"", String.class);
System.out.println("String: " + str);
You need to prepare Java Object to read your proposed JSON. But, you don't need to write code by yourself. There is a website providing automatical JSON object generator.
jsonschema2pojo
enter following items:
Target language: Java
Source type: JSON
Annotation type: Gson
and enter your class name, for example "ParsedSentence"
then, write code. You will get object.
Gson gson = new Gson();
ParsedSentence parsed = gson.fromJson(longLongJsonString, ParsedSentence.class);
I have the GSON library in my project, I need the ext_id. I am able to access "images" using the JSON.get("images"), however I am unable to get into the images array. Can someone please help me with this.

You can try this one.
public void parse(String jsonString) {
JsonElement jelement = new JsonParser().parse(jsonString);
JsonObject jobject = jelement.getAsJsonObject();
JsonArray jarray = jobject.getAsJsonArray("images");
for(int i=0;i<jarray.size();i++){
JsonObject jsonObject = jarray.get(i).getAsJsonObject();
String result = jsonObject.get("ext_id").toString();
System.out.println(result);
result = jsonObject.get("height").toString();
System.out.println(result);
}
}
You can also look here
JsonArray jsonArray = (JsonArray)jObject3.get("images");
JsonObject jObject4 =(JsonObject) jsonArray.get(0);
System.out.println(jObject4.get("ext_id"));
System.out.println(jObject4.get("full_image_path"));
My data is like this:
{
"region":
["{'price':'119','volume':'20000','pe':'0','eps':'4.22','week53low':'92','week53high':'134.4','daylow':'117.2','dayhigh':'119.2','movingav50day':'115','marketcap':'0','time':'2015-11-25 05:13:34.996'}",
"{'price':'112','volume':'20000','pe':'0','eps':'9.22','week53low':'92','week53high':'134.4','daylow':'117.2','dayhigh':'119.2','movingav50day':'115','marketcap':'0','time':'2015-11-25 05:13:34.996'}",
"{'price':'118','volume':'20000','pe':'0','eps':'1.22','week53low':'92','week53high':'134.4','daylow':'117.2','dayhigh':'119.2','movingav50day':'115','marketcap':'0','time':'2015-11-25 05:13:34.996'}"
]
}
I am doing like below;
JSONObject jsonObj = new JSONObject(jsonString);
JSONArray regionArray = jsonObj.getJSONArray("region");
How do I get each price..
for (int i = 0; i < regionArray.length(); i++) {
JSONObject item = regionArray.getJSONObject(i);
System.out.println(item.getString("price"));
}
Caused by: com.gemstone.org.json.JSONException: JSONArray[0] is not a JSONObject.
You have an array of Strings, not of JSON objects, so you can't do JSON object methods on it.
In order for your code to work, your JSON would have to look like this:
{
"region": [
{
"price": "119",
"volume": "20000",
"pe": "0",
"eps": "4.22",
"week53low": "92",
"week53high": "134.4",
"daylow": "117.2",
"dayhigh": "119.2",
"movingav50day": "115",
"marketcap": "0",
"time": "2015-11-25 05:13:34.996"
},
{
"price": "112",
"volume": "20000",
"pe": "0",
"eps": "9.22",
"week53low": "92",
"week53high": "134.4",
"daylow": "117.2",
"dayhigh": "119.2",
"movingav50day": "115",
"marketcap": "0",
"time": "2015-11-25 05:13:34.996"
},
{
"price": "118",
"volume": "20000",
"pe": "0",
"eps": "1.22",
"week53low": "92",
"week53high": "134.4",
"daylow": "117.2",
"dayhigh": "119.2",
"movingav50day": "115",
"marketcap": "0",
"time": "2015-11-25 05:13:34.996"
}
]
}
I just replaced that automatically in a text editor. You can actually let the numbers out of their "" enclosure if you want.
Have a look at it here: http://www.jsoneditoronline.org/
And here's some info on Json: http://www.json.org/
I can't understand, why I have this error:
04-24 22:11:51.263: W/System.err(27504): org.json.JSONException: Value
<!--HERE JSON VALUE--> at data of type org.json.JSONObject cannot be
converted to JSONArray
This is my code:
JSONObject getProgile = null;
try {
//get json
getProgile = new JSONObject(CustomHttpClient.executeHttpGet(profileGetURL).toString());
//convert array
JSONArray array = getProgile.getJSONArray("data");
for (int i = 0; i < array.length(); i++) {
JSONObject c = array.getJSONObject(i);
//get TAG_CUSTOMER
JSONObject customer = c.getJSONObject("Customer");
pName = customer.getString("name");
pLname = customer.getString("name");
}

JSON shows data is JSONObject rather than JSONArray, so call getProfile.getJSONObject ("data")
The problem is that you are trying to convert and JSON Object with JSON array therefore an error will occur.
If you just want to get the name then you can do this:
getProgile = new JSONObject(CustomHttpClient.executeHttpGet(profileGetURL).toString());
JSONObject obj1 = getProgile.getJSONObject("data");
JSONObject obj2 = array.getJSONObject("Customer");
String name = obj2.getString("name");
