代码如下。我的程序运行顺利，除了两个问题。它不仅仅玩三回合，我需要玩三回合，并根据在三回合中至少有过一次平局的人(如果有平局)来确定获胜者(如果随机考虑这种情况)。直到玩家或计算机的赢率达到2比1为止。我不希望它像这样连续运行。另一个问题是，一旦宣布了最终的获胜者，“输入石头，纸张或剪刀”行将再次出现，并且在那里不需要。我该如何解决这两个问题？谢谢。

最佳答案
该代码看起来应该可以按照您希望的方式工作，除了在平局的情况下，您不会增加舍入计数器:
if(USER == PC){
if(USER == SCISSOR){
System.out.println("Scissors v Scissors! Tie!");
rnd++;
}
if(USER == ROCK){
System.out.println("Rock v Rock! Tie!");
rnd++;
}
if(USER == PAPER){
System.out.println("Paper v Paper! Tie!");
rnd++;
}
System.out.println("Player has won " + wins + " times and the computer has won " + losses + " times");
System.out.print("Enter \"Rock\", \"Paper\" or \"Scissors\" \n");
}
附带说明一下，您可以从每个单独的结果中取出
rnd++;，并在每次从用户那里得到输入时都增加ojit_code，因为无论如何它都希望它增加。第二个问题是由于您在告诉用户结果(包括最终结果)后，每次收到输入时都会提示您输入新输入。您可以通过从各个结果中删除提示命令并将其放置在while循环的开始处来解决此问题。请注意，如果执行此操作，您可能还希望从欢迎消息中删除该提示，否则它将在开始时提示两次:一次在欢迎消息中，然后在while循环立即开始时再次提示。
