How do you treat a tapped card as a first tapped card variable?

I don't know Java, so this is a general coding method.

You can make a decision by combining many if statements, but I think it's better to prepare a function like this that abstracts the judgment logic.

 boolean Overlapping cards (list of cards previously flipped, new cards) {
    for {
        if (card == new flipped card) return true;
    }
    return false;
}

Also, every time you flip a new card,
1. Call the Overlapping Card Function
2. Add a flipped card to the
List of cards you have flipped so far
You should repeat this process.
No matter how many pages you flip, you can just call this function.

You may be able to use the contents().
No matter how many cards you have or how many times you flip, you can handle them.

ArrayList<Cards>cards=newArrayList<>();

// The card was flipped over.
if(cards.contains)) {
    // the same design (have been turned over in the past)
} else{
    // Different designs (for the first time
    cards.add; // keep added
}
