java语言实现：利用递归方法求n!

public class DiGui{    public static void main(String[] args){        System.out.println("请输入一个整数：");        Scanner s = new Scanner(System.in);        int n = s.nextInt();        System.out.println(method(n));    }    public static long method(int n)    {        long value = 0;        if(n == 1)        {            value = 1;        }        else        {            value = n * method(n-1);        }        return value;    }}
