Java 使用用户输入填充ArrayList

我相信这个问题已经被问过1000次了，但我无法用我的生命来证明这一点。我已经搜索了stack overflow、google、code ranch等，但找不到我要找的内容。我需要能够获取一个数字，并在生成时将其添加到ArrayList中。程序生成一个随机数，然后让用户尝试猜测它是什么。我可以获得正确填充的猜测数，但无法将其存储在ArrayList中。我需要每个猜测都在一个新的索引中，我不知道由于用户决定玩多少游戏，我需要多少。我甚至不确定ArrayList是否是我需要使用的。存储它们的意义在于，我可以在程序的后面找到最大数量的猜测。下面是我猜测数字并向用户显示的代码。我使用猜测作为int来存储来自用户猜测的信息。我是JAVA新手，所以请原谅所有的评论，让我跟上进度

    public static void guessNumber() {

    //Totals the games played by the user
    gamesPlayed++;
    //Scanner to allow user input
    Scanner console = new Scanner(System.in);
    //Prints "Your guess ? " for the user to input their guess
    System.out.print("Your guess ? ");
    // Input for the number the user guessed
    int numberGuessed = console.nextInt();

    //While loop with nested if statement to check if the number guessed by the user is equal to the random number generated, if not,
    //show higher or lower hints depending on the guess
    while (numberGuessed != randomNumber) {

        //if statement to determine if the guess is higher or lower than the random number
        //if the guess is higher, show the random number is lower than the guess, than ask the user to guess again
        if (numberGuessed > randomNumber) {
            //Prints "lower" for the user to know the number is lower than the guess, 
            //Prints "Your guess ? " for the user to guess again
            System.out.println("lower");
            System.out.print("Your guess ? ");

您使用的

列表的唯一位置是：

System.out.println("");      
ArrayList<Integer> test = new ArrayList<Integer>();
for (int i = 0; guesses > i; i++) {
    test.add(guesses);
    System.out.println("Elements of ArrayList of Integer Type: "+ test);
}

第一次是浪费的——它的返回值是未使用的
 “我无法将其存储在ArrayList”是什么意思？它不编译吗？当您执行
System.out.println（“整数类型的ArrayList的元素：“+test”）时，它是否编译并正确打印列表？它编译并运行，我在获取多个要写入数组的条目时遇到问题。我已经厌倦了int.Next（）尝试让它移动到下一个位置，我已经做了一段时间，但也没有成功。我真的不知道我是否需要这个循环。我需要它将数字写入数组，然后当用户再次猜测时，它将下一个值写入同一数组。我能解释的最好办法是，第一个猜测将保存在0位置，第二个猜测保存在1位置，依此类推。谢谢，o
