java编写程序计算表达式1！+2！+3！+……+10！的和。

public class FactorialSum {
    public static void main(String[] args) {
        int sum = 0;
        for (int i = 1; i <= 10; i++) {
            sum += factorial(i);
        }
        System.out.println("1!+2!+3!+...+10! = " + sum);
    }

    public static int factorial(int n) {
        int result = 1;
        for (int i = 1; i <= n; i++) {
            result *= i;
        }
        return result;
    }
}
