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:

1/2 + 1/3 + 1/4 + .......... 1/10

Program:

public class RansariOverloadSeries {

    // Overloaded method to calculate the sum of powers of x up to n
    void series(int x, int n) {
        long sum = 0;
        for (int i = 1; i <= n; i++) {
            sum += Math.pow(x, i);
        }
        System.out.println("Sum = " + sum);
    }

    // Overloaded method to print the first p terms of the sequence i^3 - 1
    void series(int p) {
        for (int i = 1; i <= p; i++) {
            int term = (int) (Math.pow(i, 3) - 1);
            System.out.print(term + " ");
        }
        System.out.println();
    }

    // Overloaded method to calculate the sum of a harmonic series from 1/2 to 1/10
    void series() {
        double sum = 0.0;
        for (int i = 2; i <= 10; i++) {
            sum += 1.0 / i;
        }
        System.out.println("Sum = " + sum);
    }
}

// Main class to test the RansariOverloadSeries methods
class Main {
    public static void main(String[] args) {
        // Create an object of RansariOverloadSeries
        RansariOverloadSeries series = new RansariOverloadSeries();

        // Test the method: series(int x, int n)
        System.out.println("Testing series(int x, int n):");
        series.series(2, 5); // Example: x = 2, n = 5

        // Test the method: series(int p)
        System.out.println("Testing series(int p):");
        series.series(5); // Example: p = 5

        // Test the method: series()
        System.out.println("Testing series():");
        series.series();
    }
}

Output:

Testing series(int x, int n):
Sum = 62
Testing series(int p):
0 7 26 63 124 
Testing series():
Sum = 1.9277777777777778
