Question

我希望程序打印输出，直到用户键入“再见”为止。但是，当我键入“ bye”时，循环/程序不会停止。方法如下：

Answer 1

尝试while循环

while(!(userInput.equalsIgnoreCase("bye")))  {
         System.out.println(chatty.getResponse(userInput));
         userInput = myScanner.nextLine();
    }

Answer 2

根据您的代码，如果用户在应用程序启动后立即输入"bye"，则由于循环外的scanner.next()行代码而无法使用。首次输入后，您的程序将正常运行。要解决此问题，只需在循环外部删除scanner.next()条目。

public static void startConversation(ChattyBot chatty) {
Scanner myScanner = new Scanner(System.in);
String userInput;
do
{
     userInput = myScanner.nextLine();
     System.out.println(chatty.getResponse(userInput));
}
while (!(userInput.equalsIgnoreCase("bye"))); 
}

我不明白为什么我的Do-While循环不会终止
