java————用递归算法求阶乘

public static void main(String[] args) {
int i;
System.out.println("请输入需要阶乘的一个整数:");
Scanner scanner = new Scanner(System.in);
i = scanner.nextInt();
System.out.println(i + "的阶乘是：" + jc(i));

}

public static int jc(int i) {
if (i == 0 && i == 1) {
return 1;
} else if (i > 0) {

int result = i * jc(i - 1);
return result;
} else {
return 1;
}

}
