这是我正在尝试制作的游戏。您以$1500开始游戏，每次要玩游戏都必须支付$100。（选择1玩）（按2阅读规则）（按3查看高分）游戏是抛硬币游戏. 游戏开始时，底池中有 4 美元。当它出现正面时，底池中的钱翻倍，你再次翻转。当它是尾巴时，您将获得底池中的所有钱。当您的资金少于 100 美元时，您就破产了（游戏结束）。你回到开始菜单......我希望让这个游戏记录你的最高奖金（高分）所以这就是我到目前为止得到的......

public class COINFLIP
{
public static void main(String[] args)
{
int tail = 0;//tail
int head = 0;//head
int x = 0;//tries
while (x < 1)
{
    int coin;//coin
    coin = (int) (Math.random() * 2);
    x++;
    if (coin == 0) {
    headCount++; // int type
    wasHeads = true; // boolean type
    wasTails = false;
  } else {
    tailCount++;
    wasHeads = false; // boolean type
    wasTails = true;
 }
    int sm = 1500;//starting money
    int cm;//current money
    int pm = 4;//money in the pot
    cm = sm - 100 + pm;
}
if (wasHeads)
{
pm = pm * 2;
}
else if (wasTails)
{
System.out.println("Your money is: $" + cm);
}
if (cm < 100);
System.out.println("Sorry, but you are broke!!!");
}
}

但是有很多错误，我的语句仍然有错误......我认为问题出在 if 语句中，我认为我仍然无法设置 head = true 然后在 if 语句中使用它......有什么想法吗？

如果您更正了缩进，您可能会注意到

if (coin == 0)  
{
    headCount++; // int type   
}
    wasHeads = true; // boolean type

wasHeads不在 if 语句中，将 100% 的时间执行。对于wasTails = true;

这意味着稍后您的测试if (wasHeads)将始终执行。

另外，为什么要把它放在一个while循环中，因为它只会执行一次。

关于您的错误，您需要先定义变量，然后才能使用它们。

例如

headCount++;

首先需要定义为

int headCount = 0;

您对布尔值的分配不在它们各自的测试用例中（您应该更喜欢简单的else）。所以像，

if (coin == 0) {
  headCount++; // int type
  wasHeads = true; // boolean type
  wasTails = false;
} else {
  tailCount++;
  wasHeads = false; // boolean type
  wasTails = true;
}
