Function Overloading - Sum of Series Program - ICSE 2016 Computer Science

Design a class to overload a function sumSeries() as follows:
(i) void sumSeries(int n, double x): with one integer argument and one double argument to find and display the sum of the series given below:
s = x / 1 – x / 2 + x / 3 – x / 4 + x / 5 … N terms.
(ii) void sumSeries(): to find and display the sum of the following series:
s = 1 + (1 × 2) + (1 × 2 × 3) + … + (1 × 2 × 3 × 4 … × 20)

class Overload{
    public static void sumSeries(int n, double x){
        double s = 0.0;
        for(int i = 1; i <= n; i++)
            s += x / i;
        System.out.println("Sum = " + s);
    }
    public static void sumSeries(){
        long s = 0L;
        long f = 1L;
        for(int i = 1; i <= 20; i++){
            f *= i;
            s += f;
        }
        System.out.println("Sum = " + s);
    }
}
