Question

我似乎无法让这个错误消失。它说在最后一行：解析时到达文件末尾，有人可以帮我吗？

class scanner
{ 
    class Factorial
    {
        public static void main(String args[])
        {
            int n, c, fact;

            System.out.println("Enter an integer to calculate it's factorial");
            Scanner in = new Scanner(System.in);

            n = in.nextInt();

            if ( n < 0 )
                System.out.println("Number should be non-negative.");
            else
            {
                for ( c = 1 ; c <= n ; c++ )
                    fact = fact *c;

                System.out.println("Factorial of "+n+" is = "+fact);
            }
        }
    }

你最后错过了一个括号“}”，这就是它抛出错误的原因。

更正了代码语法，也解决了其他错误。

编辑：正如@Pshemo所说，你不需要“类扫描器”，所以我评论说，但你可以删除评论真实的

import java.util.Scanner;

//public static class scanner
//{ 
    public static class Factorial
    {
        public static void main(String args[])
        {
            int n, c, fact;

            System.out.println("Enter an integer to calculate it's factorial");
            Scanner in = new Scanner(System.in);

            n = in.nextInt();

            if ( n < 0 )
                System.out.println("Number should be non-negative.");
            else
            {
                for ( c = 1 ; c <= n ; c++ )
                fact = fact *c;

                System.out.println("Factorial of "+n+" is = "+fact);
            }
        }
    }
//}
