Remarks

Thrown to indicate a problem with the JSON API. Such problems include: <ul> <li>Attempts to parse or construct malformed documents <li>Use of null as a name <li>Use of numeric types not available to JSON, such as Double#isNaN() NaNs or Double#isInfinite() infinities. <li>Lookups using an out of range index or nonexistent name <li>Type mismatches on lookups </ul>

Although this is a checked exception, it is rarely recoverable. Most callers should simply wrap this exception in an unchecked exception and rethrow:

public JSONArray toJSONObject() {
                try {
                    JSONObject result = new JSONObject();
                    ...
                } catch (JSONException e) {
                    throw new RuntimeException(e);
                }
            }
