Class Overview

Thrown to indicate a problem with the JSON API. Such problems include:

  • Attempts to parse or construct malformed documents
  • Use of null as a name
  • Use of numeric types not available to JSON, such as NaNs or infinities.
  • Lookups using an out of range index or nonexistent name
  • Type mismatches on lookups

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);
