使用JAVA求n的阶乘

使用JAVA求n的阶乘，用for循环来实现题目

int result = 1;
for (int i = 2; i <=n ; i++){
result *= i;
}

import java.util.Scanner;

public class Test {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int n = scanner.nextInt();
        long result = 1;
        for (int i = 2; i <= n; i++) {
            result *= i;
        }
        System.out.println(result);
    }
}

输出示例

package hello;

import java.util.Scanner;

public class Hello {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int n;
        n=in.nextInt();
        int i=1,sum=1;
        for(i=1;i<=n;i++)
        {
            sum=sum*i;
        }
        System.out.print(sum);
    }
}
