ObjectInputStream이 NotSerializableException을 던지고

Question

ObjectInputStream을 사용하여 .dat 파일에서 객체 배열 (PWlist)을 읽으려고합니다. 배열에는 LongPW과 PinPW이라는 두 개의 서로 다른 개체가 포함되어 있습니다. 내가 읽기를 수행하려고 할 때, 나는이 예외를 얻고있다 ...

누군가가 나에게 무엇이 잘못되었는지를 이해하는 데 도움이 시겠어요

Answer 1

java.io.NotSerializableException: PinPW는 PinPW이 PinPW에 따라서 마크 직렬화 할 수없는 클래스 의미 Serializable를 구현하십시오

public class PinPW implements Serializable { 

}
