My class java has suddenly become un-serializable_问答_开发者

One of my classes has suddenly started to complain about it being non-serializable. I have changed some things in it but can't see anything in its definitions that could be causing it.

I get the notserializableexception on that class.

These are all the definitions at the start of the class and I can't see anything there that would cause problems.

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;

These are the two comparators I have that may be are creating the problems:

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();
}
};

According to the stack trace, class il.co.anykey.games.yaniv.lite.Hand$1 (an anonymous class inside class Hand) is not serializable.

Try marking fields that are having problems as transient. Perhaps you can reconstruct them later when you deserialize.
