If I had an array of integers, like so: `int array[] = {1,2,3,4,5};`

How would I convert this array to JSON so that it is in this format  
`{ "array" : [1, 2, 3, 4, 5] }`

I am not sure what’s best inside my Processing(Java) code.

The documentation is not clear to me as to how to do this.  
[https://processing.org/reference/JSONArray.html](https://processing.org/reference/JSONArray.html)  
[https://processing.org/reference/JSONObject.html](https://processing.org/reference/JSONObject.html)

If anyone can help, that’ll be most greatly appreciated.

Thanks

```auto
int[] intsArray = { 3, 0, -1 };
println(str(intsArray));
println();

JSONArray intsJson = new JSONArray(new IntList(intsArray));
println(intsJson);

exit();

Thanks, that’s most helpful.

I like the way you used a new IntList within a new JSONArray - that’s a neat trick.

```auto
new JSONArray(new IntList(intsArray));

```
