java 打印n的阶乘 java计算并输出n的阶乘

import java.util.Scanner;

public class 阶乘 {
static int jiecheng(int n) {
	if(n==1) return 1;
	return  n*jiecheng(n-1);
}
	public static void main(String[] args) {
		Scanner s =new Scanner(System.in);
		System.out.println("输入你想要的整数：\n");
		int n =s.nextInt();
        System.out.println(+n+"的阶乘为"+jiecheng(n));
	}

}
