Newbie here... I need to address the following two "data" arrays in this JSON file individually so I can save them in different int arrays:
{
//other stuff ...
"layers":[
{"data":[1, 1, 1, 1, 5, 1, 1, 1...],
//other stuff ...
},
{"data":[1, 1, 1, 1, 5, 1, 1, 1...],
//other stuff...
}
],
//other stuff...
}
thats the code I have so far :
@SuppressWarnings("unchecked")
private void loadJsonData() {
JSONParser parser = new JSONParser();
try {
Object obj = parser.parse(new FileReader(path));
String jsonStr = obj.toString();
JSONObject json = (JSONObject) JSONValue.parse(jsonStr);
//other code...
mapTiles = ...;
objectTiles = ...;
} catch (ParseException ex) {
ex.printStackTrace();
} catch (FileNotFoundException ex) {
ex.printStackTrace();
} catch (IOException ex) {
ex.printStackTrace();
} catch (ClassCastException ex) {
ex.printStackTrace();
}
}
Im sure the answer is somwehere out there but Im too incompetent to find it :D
There are a ton of resources and the json org library is easy to use.
You can find more EXAMPLES over here
JSONParser parser = new JSONParser();
Object parsedObject = parser.parse(jsonStr);
JSONObject jsonObject = (JSONObject) parsedObject;
JSONArray layers = (JSONArray) jsonObject.get("layers");
JSONObject data = (JSONObject) layers.get(0);
JSONArray mapData = (JSONArray) data.get("data");
int[] mapTile = new int[mapData.size()];
for (int i = 0; i < mapData.size(); i++) {
mapTile[i] = ((Long)mapData.get(i)).intValue();
}
data = (JSONObject) layers.get(1);
JSONArray objectData = (JSONArray) data.get("data");
int[] objectTile = new int[objectData.size()];
for (int i = 0; i < objectData.size(); i++) {
objectTile[i] = ((Long)objectData.get(i)).intValue();
}
System.out.println(Arrays.toString(mapTile));
System.out.println(Arrays.toString(objectTile));
