从1加到8的阶层的和用java实现

以下是使用Java语言实现从1加到8的阶层的和的代码：

public class Main {
    public static void main(String[] args) {
        int sum = 0;
        for (int i = 1; i <= 8; i++) {
            int factorial = 1;
            for (int j = 1; j <= i; j++) {
                factorial *= j;
            }
            sum += factorial;
        }
        System.out.println("从1加到8的阶层的和为：" + sum);
    }
}

运行结果为：

从1加到8的阶层的和为：41113

用Java代码实现1到n的阶乘向加

public class FactorialSum {
public static void main(String[] args) {
int n = 5;
long sum = 0;
long factorial = 1;
for (int i = 1; i <= n; i++) {
factorial *= i;
sum += factorial;
}
System.out.println("1到" + n + "的阶乘向加为：" + sum);
}
}

实现1的阶乘到100的阶乘的和Java

public class FactorialSum {
public static void main(String[] args) {
long sum = 0;
long factorial = 1;

for (int i = 1; i <= 100; i++) {
factorial *= i; // 计算 i 的阶乘
sum += factorial; // 累加阶乘的值
}

System.out.println("1! + 2! + 3! + ... + 100! = " + sum);
}
}
