            JSONArray array=new JSONArray(json);
            int dl = array.length();
            System.out.println(dl);

            deptList.add(d);
            for (String e : d) {
                System.out.println(e);

you forgot

String[] d = new String[array.length];

So String array d is never initialised.. and you try it access its 1st element saying d[i]

You did not initialize your string array:

int dl = array.length();
System.out.println(dl); 
String[] d = new String[dl];
