Q:

How to get a certain elements inside an array inside a jsonObject

I'm exporting some data in java using JSON then I'm reading that data and trying to get elements from an array inside the JSON object but I'm having issues.
I have tried a lot of things like 
jsonObject.get("InGameCord").get("x")
Object Testo = jsonObject.get("InGameCord");
Testo.x

Things like that along with more that did not work so deleted the code.
This is the exported JSON file and im trying to access the InGameCord array X or Y. 
{"BaseID":1,"BaseName":"Bandar-e-Jask Airbase","InGameCord":[{"x":463,"y":451}]}

Here is my file reader code
FileReader reader = new FileReader(filename);
JSONParser jsonParser = new JSONParser();
JSONObject jsonObject = (JSONObject) jsonParser.parse(reader);
System.out.println(jsonObject);
System.out.println("BaseName: "+jsonObject.get("BaseName"));
System.out.println("BaseID: "+jsonObject.get("BaseID"));
System.out.println("InGameCord: "+jsonObject.get("InGameCord"));

All of this works and exports the correct info.
So I'm trying to get let us say the X value of InGameCord.
int X = 463;

A:

Given your JSON data {"BaseID":1,"BaseName":"Bandar-e-Jask Airbase","InGameCord":[{"x":463,"y":451}]}:

"InGameCord" is the name of an array which can be instantiated as a JSONArray.
That array contains only one element: {"x":463,"y":451}.
That array element can be instantiated as a JSONObject. It contains two name/value pairs:

"x" with the value 463.
"y" with the value 451.

So based on the code you provided, to instantiate the JSONArray:
JSONArray numbers = (JSONArray) jsonObject.get("InGameCord");
To retrieve the first (and only) element of the array into a JSONObject:
JSONObject jObj = (JSONObject) numbers.get(0);
To get the value for "x" into an int variable cast the Object returned by get() to a Number, and then get its intValue():
int value = ((Number) jObj.get("x")).intValue();
You can even do the whole thing in one line, but it's ugly:
int y = ((Number) ((JSONObject) numbers.get(0)).get("y")).intValue();
