A simple Java toolkit for JSON. You can use json-simple to encode or decode JSON text. - fangyidong/json-simple

public static void main(String[] args) throws IOException, JSONException, ParseException { try { JSONParser parser = new JSONParser(); Object obj = parser.parse(new FileReader("/home/Desktop/temp.json")); JSONObject objJsonObject = new JSONObject(obj.toString()); System.out.println(objJsonObject); JSONArray Liste = objJsonObject.getJSONArray("ListeCar"); String listeCar = Liste.getJSONObject(0).getString("id"); for (int i = 0; i < Liste.length(); i++) { String id = Liste.getJSONObject(i).getString("id"); System.out.println(id); String size = Liste.getJSONObject(i).getString("size"); System.out.println(size); String Orientation = Liste.getJSONObject(i).getString("Orientation"); System.out.println(Orientation); String Position = Liste.getJSONObject(i).getJSONObject("Position").toString(); System.out.println(Position); } } catch (JSONException e) { e.printStackTrace(); } }

June 20, 2025 - In this tutorial, we’ll see how to create, manipulate, and parse JSON using one of the available JSON processing libraries in Java – the JSON-Java library, also known as org.json.

March 14, 2013 - import org.json.simple.parser.JSONParser; import org.json.simple.parser.ParseException; class JsonDemo { public static void main(String[] args) { JSONParser parser = new JSONParser(); String text = "[[null, 123.45, \"a\tb c\"]}, true"; try{ Object obj = parser.parse(text); System.out.println(obj); }catch(ParseException pe) { System.out.println("position: " + pe.getPosition()); System.out.println(pe); } } }

August 4, 2022 - For reading JSON from file, we have to use org.json.simple.parser.JSONParser class. JSONParser parse method returns JSONObject. Then we can retrieve values by passing key names.

File jsonFile = new File("/hello.json"); // Do with as you please /* * Simple key value pairs */ JSONParser parser = new JSONParser(); try{ JSONObject jObj = (JSONObject) parser.parse(new FileReader(jsonFile)); } catch (IOException | ParseException e) { e.printStackTrace(); } String value = (String) jObj.get("world"); long delay = (Long) jObj.get("delay"); boolean debug = (Boolean) jObj.get("debug"); /* * JSONArray */ JSONArray array = (JSONArray) jObj.get("array"); /* * JSONObject inside JSONObject */ try{ JSONObject user = (JSONObject) parser.parse(jObj.get("user").toString()); } catch (IOException | ParseException e) { e.printStackTrace(); } String username = (String) user.get("username"); // JSON Simple imports import org.json.simple.JSONArray; import org.json.simple.JSONObject;

December 24, 2025 - JSON is a light-weight, language independent, data interchange format. See http://www.JSON.org/ The files in this package implement JSON encoders/decoders in Java. It also includes the capability to convert between JSON and XML, HTTP headers, Cookies, and CDL.

Online JSON Parser helps to parse, view, analyze JSON data in Tree View. It's a pretty simple and easy way to parse JSON data and share it with others.

public static String getJsonWithUpdatedResources(String jsonConf, Map<String, Double> resourceUpdates) { try { JSONParser parser = new JSONParser(); Object obj = parser.parse(jsonConf); JSONObject jsonObject = (JSONObject) obj; Map<String, Double> componentResourceMap = (Map<String, Double>) jsonObject.getOrDefault( Config.TOPOLOGY_COMPONENT_RESOURCES_MAP, new HashMap<String, Double>() ); for (Map.Entry<String, Double> resourceUpdateEntry : resourceUpdates.entrySet()) { if (NormalizedResources.RESOURCE_NAME_NORMALIZER.getResourceNameMapping().containsValue(resourceUpdateEntry.getKey())) { // i

May 13, 2024 - The following example uses JSON.simple to read JSON from a file named person.json and print out the values.
