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

public class KboatOverloadSeries
{
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);
}
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();
}
void series() {
double sum = 0.0;
for (int i = 2; i <= 10; i++) {
sum += 1.0 / i;
}
System.out.println("Sum = " + sum);
}
}Output
