黑杰克游戏的问题，当用户点数突破 21 时，将 Ace 的值从 11 更改为 1

Question

So I'm trying to make a Black Jack game in Java. However, I've been having an issue with making the user's Hand point value drop from when it goes over 21 and has an Ace. I thought this would be simple 'if handArray has an Ace type and points>21 -> change value of Ace'.

But this is proving to be fairly difficult. Maybe I'm overthinking it, but my vrain is fried and I'm tired of looking at this lol. Here is my code: Basically I have a Card object with a value, all the cards are stored in an array, then I have Hand object that stores an array of Cards:

    int sumUser = 0;
    userHand.points= 0;
    boolean ace=false;
    for(int i = 0; i < userHand.handArray.size(); i++) {
        //System.out.println(userHand.handArray.get(0).type +userHand.handArray.get(1).type );
        
        
        if(userHand.handArray.get(i).type=="Ace") {
            if (userHand.points>21) {
            userHand.handArray.get(i).value= userHand.handArray.get(i).otherValue;
            System.out.println("saved by the ace");
            }
        }
        
        sumUser = sumUser + userHand.handArray.get(i).value;
        userHand.points = sumUser;
        System.out.println(userHand.points);
        
        if (userHand.points>21) {
            System.out.println("Bust, loser");
            
            btHit.setDisable(true);
            btRetry.setVisible(true);
            userHand.handArray.removeAll(userHand.handArray);
            
        }

Answer:

       dealerHand.points= 0;
        boolean ace = false;
        for(int i = 0; i < dealerHand.handArray.size(); i++) {
            
            
            //Checks dealer hand for an ace 
            if(dealerHand.handArray.get(i).type=="Ace") {
                ace = true;
                System.out.println("You have an ace");  
            }
        
            dealerHand.points += dealerHand.handArray.get(i).value;
            
            //if the hand breaks 21 and has an ace, the ace value is reassigned to one and the 
            //hand points value is recalculated
            if (dealerHand.points>21 && ace==true) {
                dealerHand.points = 0;
                for( i = 0; i < dealerHand.handArray.size(); i++) {
                    if(dealerHand.handArray.get(i).type=="Ace") {
                        dealerHand.handArray.get(i).value=dealerHand.handArray.get(i).otherValue;
                        System.out.println("Dealer Ace new value "+dealerHand.handArray.get(i).value);
                        
                        
                    }dealerHand.points += dealerHand.handArray.get(i).value;
                    System.out.println("New dealer hand points value "+dealerHand.points);
                }
