如何随机生成猜测

Question

我对Java还是有点陌生，有一个实验室需要模拟一个彩票游戏，生成一个介于1到10之间的数字。它首先询问用户想要购买多少张彩票，然后询问他们是否希望计算机为他们生成猜测，如果是，则会生成猜测并显示中奖号码。如果用户说不，那么用户将自己输入猜测，并显示中奖号码。

我在弄清楚当有人输入是或否时如何执行代码时遇到了问题。我应该做一个do while循环吗？

这是我现在的代码。

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);


    double TICKET_PRICE = 2.00;

    System.out.println("Welcome to the State of Florida Play10 Lottery Game. Ticket Price: $" + TICKET_PRICE);

    System.out.println("How many tickets would you like to purchase?");
    int ticketsPurchased = input.nextInt();

    System.out.print("Please enter " + (ticketsPurchased) + " to confirm your credit carde charge: ");
    int creditCardCharge = input.nextInt();

    if (ticketsPurchased != creditCardCharge) {
        System.out.println("Wrong number, please enter again: ");
        return;
    }
    if (ticketsPurchased == creditCardCharge) {
        System.out.println("Thank you. Your credit card will be charged $" + (ticketsPurchased * 2));
    }
    int min = 1;
    int max = 10;
    int winner;
    winner = min + (int)(Math.random() * ((max - min) + 1));



    System.out.print("Would you like the computer to generate your guesses? Enter 'Y' or 'N': ");
    String computerGeneratedGuess = input.nextLine();

    int guess = 0;
    int winCtr = 0;
    String output = "";
}

以下是算法：1。获取购票数量，计算并确认信用卡费用。2.生成随机获胜整数，生成随机猜测或提示用户猜测。3.报告中奖号码、中奖彩票、总奖金、总损失和允许扣除额

这是实验室它自己：Lab05彩票游戏

一般来说，布尔值可以方便地控制这样的循环。比如：

boolean gameOver = false;
int theGuess = 0;
while (!gameOver) {
    if (computerGeneratedGuess == 'Y') {
        theGuess = //code to generate a random number
    }
    else {
        theGuess = //code to for user to enter a guess
    }
    if (theGuess == winner) {
        gameOver = true;
}
