How can I create a 2D array using a JSON file?  
“tile\_size”: 16,  
“map\_width”: 101,  
“map\_height”: 37,  
“layers”: [  
{  
“name”: “bg”,  
“positions”: [  
{ “x”:1, “y”:6, “id”:0 },  
{ “x”:1, “y”:7, “id”:0 },  
{ “x”:1, “y”:8, “id”:0 },  
{ “x”:1, “y”:9, “id”:0 },  
{ “x”:1, “y”:10, “id”:0 },  
{ “x”:1, “y”:11, “id”:0 },  
{ “x”:1, “y”:12, “id”:0 },  
{ “x”:1, “y”:13, “id”:0 },  
{ “x”:1, “y”:14, “id”:0 },  
{ “x”:1, “y”:15, “id”:0 },  
{ “x”:1, “y”:16, “id”:0 }  
]  
}  
]

You can use methods **append()** or **setJSONArray()** to add a `new` JSONArray to your existing JSONArray:
