所以我正在制作一个想要成为百万富翁游戏代码的人，并且我拥有一切完美的工作。但有时问题会重演，如果你最终得到同一个问题，那么它就不会成为一个好的游戏。我会感激所有和任何帮助。

此类事情的一个选项是创建一个包含所有问题的List，随机使用Collections.shuffle()对其进行随机播放，然后从中创建一个队列。然后你就可以从队列中弹出问题，而且你永远不会重复一个问题。可能比跟踪询问的问题更容易。
以下是使用简单的整数列表执行此操作的示例：
package test;
import java.util.ArrayDeque;
import java.util.Arrays;
import java.util.Collections;
import java.util.List;
import java.util.Queue;
public class Test {
public static void main(String[] argv) {
List<Integer> intList = Arrays.asList(1,2,3,4,5);
Collections.shuffle(intList);
Queue<Integer> intQueue = new ArrayDeque<Integer>(intList);
Integer x;
while ((x = intQueue.poll()) != null) {
System.out.println(x);
}
}
}

跟踪ArrayList中已经提出的问题（或者，您可以使用任何类型的存储方法），并检查该列表以查看您提出的问题是否属于您之前曾问过要问。如果是这样，请问一个不同的问题。否则，问问题。
我不打算为你调试那个大规模的代码转储，我怀疑我们中的许多人会这样做。请阅读How to Ask以提高您获得更好答案的机会。
答案 2 :(得分：0)
在提出第一个问题时，不要使用随机数。生成随机数列表，在提出问题之前会询问问题。
使用LinkedHashSet来维护随机序列和唯一性。
Set<Integer> generated = new
LinkedHashSet<Integer>();
while (generated.size() < numbersNeeded)
{
Integer next = rng.nextInt(max) + 1;
generated.add(next);
}
