用户输入以重复Java程序

这是完整的代码，完全可以使用并经过测试。

    public static void main(String[] args)    {    String playAgain = "";    Scanner scan = new Scanner(System.in);    do    {        ClassName.inputGuess();        System.out.println("Would you like to play again? Enter Y to play or any other key to quit: ");        playAgain = scan.nextLine();    }    while(playAgain.equalsIgnoreCase("Y"));    System.out.println("Thanks for playing!");}public void inputGuess(){    Random num = new Random();    int answer = num.nextInt(10)+1;    Scanner input = new Scanner(System.in);    int guess;    System.out.println("Enter a number between 1 and 10 as your first guess: ");    guess = input.nextInt();    do    {        if (guess < 1 || guess > 10)        { System.out.println("That is not a valid entry. Please try again: "); guess = input.nextInt();        }        else  if (guess > answer) {     System.out.println("Too high, Try Again: ");     guess = input.nextInt(); } else      if (guess < answer)     {         System.out.println("Too low, Try Again: ");         guess = input.nextInt();     }        input.nextLine();    }    while (guess != answer);    System.out.println("Congratulations, You guessed the number!");}
