I think that the explanation given in the answer contains an invalid statement:
"All exceptions given in the options other than Exception, are RuntimeExceptions".
There is also "ClassNotFoundException" among the given exceptions, which is not a RuntimeException. It directly inherits from Exception, thus it's a checked exception, that IS thrown by the API (example: method readObject() and writeObject()).

You are right. It has been changed to NoClassDefFoundError and the explanation has been updated to that it is thrown by the JVM when it attempts to load a class and is unable to find the class file. It extends ///java.lang.Error/// and Errors are always thrown by the JVM. A programmer should never throw an Error explicitly.

thank you for your feedback!
