求1到18的阶乘之和

刚刚的程序不准确，可以使用下面的代码进行验证
[quote]
public class Test
{
private static long result = 1;

public static void main(String[] args)
{
    long totalResult = 0;
    for (int i = 1; i <= 18; i++)
    {
        long r = factorialN(i);
        System.out.println("-----"+i+"的阶乘：---->" + r);
        totalResult += r;
        result = 1;
    }
    System.out.println("-----totalResult---->" + totalResult);

}

// 通过递归方式获取整数n的阶乘
public static long factorialN(int n)
{
    if (n > 0)
    {
        result = result * n;
        factorialN(n - 1);
    }
    return result;
}

}

[code="java"] public static void main(String[] args) {
int end=18;
int result=1;
for(int i=2;i<end+1;i++){
result=result+i*i;
}
System.out.println(result);
