我的类java突然变得不可序列化了

标签： java android serialization

我的一个班级突然开始抱怨它不可序列化。 我已经改变了一些内容，但在其定义中看不到可能导致它的任何内容。

我在那个类上得到了notserializableexception。

这些是课程开始时的所有定义，我看不到任何会导致问题的内容。

private static final long serialVersionUID = 1L;
private ArrayList <Card> cards;
private ArrayList <Card> selectedCards;
private HashSet <Card> knownCards;
private ArrayList <Card> aceHighs;
private int numberOfKnownCards = 0;
private int valueOfKnownCards = 0;

public static final int sortHand = 1;
public static final int sortSelectedCards = 2;
protected int[] cardsPerSuit = {0,0,0,0}; 
private int numberOfDifferentSuits = 0;
private int[] cardsPerRank = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
private int numberOfDifferentRanks = 0;



private int whereToTakeFrom;
private int whichDiscardToTake;

private int cardCount = 0;
private int selectedCount = 0;
public  int handValue = 0;
private Deck deck;

这些是我可能产生问题的两个比较器：

private Comparator<Card> byRank = new Comparator<Card>()  {

public int compare(Card c1, Card c2) {
   return c2.getCardRank()-c1.getCardRank();
}
};

private Comparator<Card> bySuitAndRank = new Comparator<Card>()  {

public int compare(Card c1, Card c2) {
   return (c1.getCardSuit()-c2.getCardSuit())*100 + c2.getCardRank()-c1.getCardRank();
}
};

2 个答案:

答案 0 :(得分：3)

根据堆栈跟踪，类il.co.anykey.games.yaniv.lite.Hand$1（类Hand内的匿名类）不可序列化。

答案 1 :(得分：1)

尝试将遇到问题的字段标记为transient。也许您可以在以后反序列化时重构它们。
