Question

在JAVA中编写一个程序，该程序将模拟投掷硬币并输出连续获得三个“头”所需的投掷次数。该程序还将向模板输出模拟折腾的“头部”和“尾部”。例如，您的程序可能会产生如下输出：

实施例1：HTHHH
5
实施例2：TTTHTHHTTTHHH
14

现在，当我运行它时，它会连续打印H并且无限次运行。它也没有翻转Tails，只有头部。所以有人可以帮我修改我的代码请.....谢谢。

我的代码：

    import java.util.*;

public class threeHeads {

    public static void main(String[] args) {

        boolean first = false;
        boolean second = false;
        int count = 0;

        Random random = new Random();

          while(true){

                int n = random.nextInt(2) + 1; //1 is Heads, 2 is Tails 

                if (n == 1){
                    System.out.println("H");  
                    count++;

                if (first == false){
                    first = true;
                } else if (second == false){
                    second = true;
                } else if (second == true){
                    break;
                } 
                }
                else {
                    System.out.println("T");
                    first = false;
                    second = false;
                    count++;
                  } 

            }

          if (count == 3){
                System.out.println(count);
            }

    }
}

尝试使用此代码，看看它是否达到了您想要的效果

public class flipper {
    public static void main(String[] args) {
        int heads = 0;
        int count = 0;
        while (heads < 3) {
            int flip = (int)(Math.random() * 2);  // range [0, 1]
            count++;
            if (flip == 0) {
                System.out.print("H");
                heads++;
            } else {
                System.out.print("T");
                heads = 0;
            }
        }
        System.out.println("\nIt took " + count + " flips to achieve three heads in a row");
    }
}

连续三个Java程序？
