Java读写高分

Question

我目前正在为 Java 类编写一个程序来玩 pig 游戏，但不知道如何在文件中读取和写入高分。我希望获得有关此计划的任何可能的帮助。谢谢你!代码现在编译得很好并且运行正常，这是游戏的用户与计算机代码。这是我到目前为止的代码:

public class ComputerPig
{
    //Scanner usersName;
    String usersName="";
    Boolean humanTurn = true;
    Boolean computerTurn = true;
    int dice;
    int humanTurnPoints, computerTurnPoints;
    int humanTotalPoints = 0;
    int computerTotalPoints = 0;
    private Scanner keyboard;
    private Scanner key;
    // System.out.print("Please enter your name: ");
    // usersName = new Scanner(System.in);
    // setStart(usersName.nextLine());
    public void roll()
    {
        dice = (int) (Math.random() * 6) + 1;
    }
    public int humanTurnScore()
    {
        {
            humanTurnPoints = dice + humanTurnPoints;
            System.out.println(usersName + "threw: " + dice);
            System.out.println(usersName + "have scored: " + humanTurnPoints + " in your turn.");
        }
        return humanTurnPoints;
    }
    public void humanTurnZero()
    {
        humanTurnPoints = 0;
    }
    public int computerTurnScore()
    {
        {
            computerTurnPoints = dice + computerTurnPoints;
            System.out.println("Computer has scored: " + computerTurnPoints + " in its turn.");
        }
        return computerTurnPoints;
    }
    public void computerTurnZero()
    {
        computerTurnPoints = 0;
    }
    public ComputerPig(String xUsersName)
    {
        usersName=xUsersName;
        humanGame();
        if (!humanTurn)
        {
            computerTurn();
        }
    }
    public int humanGame()
    {
        System.out.println("To start the game please press 'r'.");
        key = new Scanner(System.in);
        String start = key.nextLine();
        if (!start.equalsIgnoreCase("R"))
        {
            System.out.println("Make sure you are pressing 'r'.");
            humanGame();
        }
        if (start.equalsIgnoreCase("R"))
        {
            System.out.println(usersName + "pressed +  'r'.");
            System.out.println("Lets start.");
            do
            {
                roll();
                if (dice == 1)
                {
                    System.out.println(usersName + " got 1 and you lost your turn.");

您可以使用纯文本文件，或者您可以了解 JSON，甚至更具体地说，GSON。

您具体希望在文件中存储哪些信息？您是否尝试过实现这一目标？粘贴您的高分代码。
