java - 不断询问用户输入，直到整数介于两个数字之间

我需要以下代码的帮助：

    int seatNum = 0;

    Scanner seatNumber = new Scanner(System.in);

    do
    {
        try
        {
            System.out.println("Please choose a seat number");
            seatNum = seatNumber.nextInt();
        }
        catch(InputMismatchException e)
        {
            System.out.println("The index you have entered is invalid");
            System.out.println("Please enter an index number between 0 and 7");

        }

    } while (seatNum <= 0 || seatNum >= 7);

基本上，我只想让seatNum在0到7之间（如果不要求用户再次输入）。当我输入一个介于0到7之间的整数时，一切都可以正常工作，但是如果我输入一个String，程序将进入无限循环。当用户输入String时，如何停止进入无限循环的程序？

最佳答案

尝试这个

String seatNum = null;
Scanner scanner = new Scanner(System.in);
while(true){
System.out.println(" Enter a number between 0 and 7");
seatNum = scanner.nextLine().toString();
if(seatNum.matches("[0-7]")) break; // makes sure user enter a number also between the range
else System.out.println("Enter between 0 and 7");

不错吧？我没有运行它，告诉它是否是您想要的
