我是编程新手。我试图制作二十一点，我遇到了一些问题。
我的控制台输出：
Would you like to play again? y/n
y
You have: $50
Whats your bet:
12
You get a 7 and a 10
Your total is 17
The dealer has a 9 11 showing
Would you like to hit? y/n :
n
The dealer has 20 //Here it is supposed to say You lost blah blah blah
Would you like to play again? y/n //but its skipping to System.println("play again");

我已经多次梳理了代码，寻找我出错的地方，比如它可能不是}，但我找不到任何东西。我觉得它可以用一些新鲜的眼睛！
在我使用此代码后，我计划再次尝试使用面向对象的方法。
答案 0 :(得分：2)
设置变量＆＃34; win＆＃34;的if语句集。不正确。
通过给出的示例遍历代码（经销商有20个，玩家有17个），变量＆＃34; win＆＃34;从来没有设置所有的陈述打印出来＃34;你输了＃34;和＃34;你赢了＆＃34;被跳过了。
很有可能在这一行
if (dealersValue > cardValue && dealersValue > 21){
你的意思
dealersValue < 21
然后将win设置为2并显示正确的输出。
调试提示：使用IDE浏览代码。如果你逐行一步，你应该立即看到它跳过设置＆＃34; win＆＃34;变量
祝学习编程好运！这很有趣但非常令人沮丧：）
