java - while 循环出错。它不会阻止 Java

Question

嘿伙计们，我有以下 while 循环，它似乎不会停止。它应该询问用户一个小时。我正在 try catch 用户未输入数字的事件。

即 输入小时: foo 您没有输入有效值

然后它应该允许用户再次输入小时值，但它会一遍又一遍地打印错误消息

    private static void setTime(Clock clock){
        int hours = -1;
        int minutes = -1;
        int seconds = -1;

        Scanner scanner = new Scanner(System.in);

        while(true)
        {
            try{
                System.out.print("Enter hours: ");
                hours = scanner.nextInt();          
            }
            catch(NumberFormatException nfe){
                System.out.println("Input was not an integer, please try again");
                continue;
            }
            catch(InputMismatchException ims){
                System.out.println("Input was not an integer, please try again");
                continue;
            }
            break;
        }
}

将 Scanner Scanner = ... 移至 while 循环中。
