计算ln(n!)的java方法递归地

public class FactorialLogarithm {
    public static double calculateFactorialLogarithm(int n) {
        if (n == 0 || n == 1) {
            return 0; // ln(0!) = ln(1!) = 0
        } else {
            return Math.log(n) + calculateFactorialLogarithm(n - 1);
        }
    }

    public static void main(String[] args) {
        int n = 5;
        double result = calculateFactorialLogarithm(n);
        System.out.println("ln(" + n + "!): " + result);
    }
}
