24.37 java.io.NotSerializableException (JDK 1.1)

This exception signals that an object could not be serialized. It is thrown when serialization is attempted on an instance of a class that does not implement the Serializable interface. Note that it is also thrown when an attempt is made to serialize a Serializable object that refers to (or "contains") an object that is not Serializable.

A subclass of a class that is Serializable can prevent itself from being serialized by throwing this exception from its writeObject() and/or readObject() methods.

public class NotSerializableException extends ObjectStreamException {
    // Public Constructors
            public NotSerializableException(String classname);
            public NotSerializableException();
}
