利用Java求1/1!+2/2!+3/3!+5/4!+8/5!+13/6!+...前10项之和

这道题目是要求前10项的和，而每一项的分子是斐波那契数列的第n项，分母是n的阶乘。可以使用循环来计算每一项的值并累加和。以下是一种可能的Java代码实现：

public static void main(String[] args) {
    double sum = 0;
    double numerator = 1;
    for (int i = 1; i <= 10; i++) {
        double denominator = factorial(i);
        sum += numerator / denominator;
        numerator += fibonacci(i);
    }
    System.out.println(sum);
}

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

static double fibonacci(int n) {
    if (n == 1 || n == 2) {
        return 1;
    }
    double prev1 = 1;
    double prev2 = 1;
    double result = 0;
    for (int i = 3; i <= n; i++) {
        result = prev1 + prev2;
        prev2 = prev1;
        prev1 = result;
    }
    return result;
}
