I made a change to push the lat/long to the screen and that is functioning ok, and I am casting the lat/long to strings to construct the URL ok, but I am now just a bit stuck why it should just fall over when just trying to push the loadJSONArray request to a JSONArray var.

Any thoughts?

JSON object format:

{
  "row": 0,
  "data": [ -128, -109, -70, ... 30, 102 ]
},

There's 32 of them labeled 0 to 31, and each "data" array has 32 values ranging from -128 to 127. I've verified that the JSON is valid.

Code:

JSONArray rawHeight;
byte[][] hmap = null;
byte[] temp = null;

void prepareHMapAndTemp() {
  for (int h = 0; h < 32; h++) {
    hmap[i] = new byte[32];
    temp[i] = new byte;
  }
}

void processHeightData() {
  for (int i = 0; i < 32; i++) {
    JSONObject row = rawHeight.getJSONObject(i);

    for (int j = 0; j < 32; j++) {
      temp = (byte[])append(hmap, row.getJSONObject("data").getInt(j));
    }
    hmap = (byte[][])append(hmap, temp);

    println(i + ": " + row);
  }
}

void setup() {
  rawHeight = loadJSONArray("map.hmp");
  prepareHMapAndTemp();
  processHeightData();
}

On temp[i] = new byte;, byte; is underlined and gives this very ambiguous error: Error on "Dimensions". Trying to run it anyways has it yelling unexpected token ";". Also, temp = (byte[])append(hmap, row.getJSONObject("data").getInt(j)); gives the error The function "getInt()" expects parameters like: "getInt(String)" even though the online reference says it takes an int for the index?

Edit: Just realized I was I started hmap without a value and temp with a value of null. Now both are be started as null. Don't think there's actually a difference, though.

I get the following values, which are outside my canvas:

Example of the Json data:

I have Processing read from a PHP file

[{“ID”:”1”,”Name”:”Adam”},
 {“ID”:”2”,”Name”:”Peter”}]                                                                                                                      

I then give them a

    "String ID = value.getString("ID");"
    "String Name = value.getString("Name");"

println(ID+Name);

Will give me

123456Adam
456Peter

How do I join them in one string and print in such that

123456Adam456Peter?

Thanks alot in advance!

I am importing values from a json file, and when I run the following code I get a Nullponter Exception error. I googled and tried different things, but unfortunately I cannot solve the problem. I am greatful for any help, here is my code:

JSONObject json;
int max;
void setup() {
  size(841,594);

JSONArray jsonArray = loadJSONArray("january_2016.json");
JSONObject jsonObject = jsonArray.getJSONObject(0); 
JSONObject maxTemperature = json.getJSONObject("Max Temperature");
int max = maxTemperature.getInt("max");

  print(max);
}

void draw(){
//Max Temperature  
  textAlign(CENTER);
  text("Max Temperature",841/4, 594/2+100);

  ellipseMode(RADIUS);
  ellipse(841/4, 594/2, max, max); // max
  ellipse(841/4, 594/2, max, max); //avg
  ellipse(841/4, 594/2, max, max); //min

}

EDIT: I put all my classes in different tabs. This is the tab Processing opened when I got the error.

public class Server { private JSONObject data; private String name; private String status; private int port; private boolean shared; private String publicURL; public Server(String newName) { name = newName; refreshData(); } //Getting---------------------- public String getName() { return name; } public String getStatus() { return status; } public String getPublicUrl() { return publicURL; } public String toString() { return data.toString(); } //Misc------------------------- public void refreshData() { JSONArray servers = null; try { servers = loadJSONArray("http://127.0.0.1:33649/server/list"); } catch (Exception e1) { launch("C:\\ProgramData\\Fenix\\Fenix.exe"); while (servers==null) { try { servers = loadJSONArray("http://127.0.0.1:33649/server/list"); } catch (Exception e2) { } } } for (int i = 0; i<servers.size(); i++) { JSONObject temp = servers.getJSONObject(i); if (temp.getString("name").equals(name)) { data = temp; } } if (data.getBoolean("starting")) { status = "Starting"; } else if (data.getBoolean("stopping")) { status = "Stopping"; } else if (data.getBoolean("running")) { status = "Running"; } else { status = "Stopped"; } port = data.getInt("port"); if (data.getBoolean("shared")) { shared = true; publicURL = data.getString("publicUrl"); } else { shared = false; publicURL = null; } } }
