将方法转换为泛型方法

Question

我正在编写一个德州扑克游戏，并创建了此方法对用户手牌进行排名，我想将其变成通用方法，以便我可以通过庄家手牌，然后比较两者，看看哪手牌会更好。如果您能帮助我将其转换为通用方法，我将不胜感激。

public int rankCards(ArrayList<Integer> rankHandList){
    //creates a list to put the card ranks into 
    ArrayList <Integer> newList;
    newList = new ArrayList<>();
    //Checks the rankHandList i created above
    for(int x = 0; x<=rankHandList.size()-1; x++){
        int rank = rankHandList.get(x);
        //takes all the cards and gets them between 0 and 12
        while(rank >= 13){
            rank = rank -13;
        }
        //if a card = 12 it is an ace
        if(rank == 12)
            newList.add(rank);
        //if a card = 11 it is a king
        if(rank == 11)
            newList.add(rank);
        //if a card = 10 it is a queen
        if(rank == 10)
            newList.add(rank);
        //if a card = 9 it is a jack
        if(rank == 9)
            newList.add(rank);
        //if a card = 8 it is a 10
        if(rank == 8)
            newList.add(rank);
        //if a card = 7 it is a 9
        if(rank ==7)
            newList.add(rank);
        //if a card = 6 it is a 8
        if(rank ==6)
            newList.add(rank);
        //if a card = 5 it is a 7
        if(rank ==5)
            newList.add(rank);
        //if a card = 4 it is a 6
        if(rank ==4)
            newList.add(rank);
        //if a card = 3 it is a 5
        if(rank ==3)
            newList.add(rank);
        //if a card = 2 it is a 4
        if(rank == 2)
            newList.add(rank);
        //if a card =1 it is a 3
        if(rank ==1)
            newList.add(rank);
        //if a card = 0 it is a 2
        if(rank ==0)
            newList.add(rank);
    }
  //SENDS THE CARDS I JUST RANKED FROM 0-12 TO MAKE THE BEST HAND   
    makeBestHand(newList);
    return 0;
}

我不完全理解你想要什么，因为我理解你想重构你的代码。

public int rankCards(ArrayList<Integer> rankHandList) {
    // Creates a list to put the card ranks into 
    ArrayList <Integer> newList = new ArrayList<Integer>();
    // Checks the rankHandList i created above
    for (int rank : rankHandList) {
        // Add card rank into the list, after module 13 to normalize rank.
        newList.add(rank%13);
    }
    //SENDS THE CARDS I JUST RANKED FROM 0-12 TO MAKE THE BEST HAND   
    makeBestHand(newList);
    return 0;
}
