Series Overload Program - ICSE 2019 Computer Science

Design a class to overload a function series() as follows:

(a) void series(int x, int n) – to display the sum of the series given below:
x1 + x2 + x3 + … xn terms

(b) void series(int p) – to display the following series:
0, 7, 26, 63, … p terms

(c) void series() – to display the sum of the series given below:

Java 

class Overload{
    public void series(int x, int n){
        double s = 0.0;
        for(int i = 1; i <= n; i++)
            s += Math.pow(x, i);
        System.out.println("Sum = " + s);
    }
    public void series(int p){
        for(int i = 1; i <= p; i++){
            int x = (int)Math.pow(i, 3) - 1;
            System.out.print(x + " ");
        }
        System.out.println();
    }
    public void series(){
        double s = 0.0;
        for(int i = 2; i <= 10; i++)
            s += 1.0 / i;
        System.out.println("Sum = " + s);
    }
}
