Question

Java write a program to calculate the factorial of any natur

Answer 1

import java.util.Scanner;

public class DiGui {

public static void main(String[] args){

//创建一个输入容器

Scanner input = new Scanner(System.in);

System.out.println("输入一个数：");

int grade = input.nextInt();

DiGui d = new DiGui();

int end = d.DiGuiDiaoYong(grade);

System.out.println("阶乘结果："+end);

}

//用递归

public static int DiGuiDiaoYong(int n){

if(n==1)

return n=1;

return DiGuiDiaoYong(n-1)*n;

}

}
