    import java.util.Scanner;
public class GuessingGameV1
{
    public static void main(String [] args)
    {
        //
        int counter = 0;
        double randNum = 0.0;
        randNum = Math.random();
        int rand = (int)(randNum*100);

        System.out.println("Please enter your guess: ");
        int guess = in.nextInt();

        while(guess !=rand)
        {
        if((guess< rand)&&(guess>=0))
        {
             System.out.println("Your guess is too low");       

        }
        else if((guess> rand)&&(guess<=100))
        {
            System.out.println("Your guess is too high");
        }
        else if (guess<0)
        {
            System.out.println("Out of Range! Please choose a number more than 0");
        }
        else if (guess<100)
        {
            System.out.println("Out of Range! Please choose a number less than or 100");
        }
        counter++;
    }
    System.out.println("You are correct! The number was " + rand);
    System.out.println("It took you " + counter + " tries to get it!");
}
}

我的节目应该是一个猜谜游戏。注意我是Java的新手，我已经重新编写了两次程序，它仍然给我错误！我的计划有什么问题？

基本上用户应该输入一个数字，程序将吐回来，应该更高或更低，再次进行直到用户正确。在他们这样做之后告诉他们他们做这件事的次数和次数。

谢谢！

你没有声明变量in。

声明：

Scanner in = new Scanner(System.in);

我做错了什么：找不到符号 - 变量。
