JSONException

public class JSONException
extends Exception

java.lang.Object
↳	java.lang.Throwable
	↳	java.lang.Exception
		↳	org.json.JSONException

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);
     }
 }
