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:
(ii) void sumSeries(): to find and display the sum of the following series:
S=1+(1×2)+(1×2×3)+⋯+(1×2×3×…×20)
Overload - Java Code

public class KboatOverload
{
void sumSeries(int n, double x) {
double sum = 0;
for (int i = 1; i <= n; i++) {
double t = x / i;
if (i % 2 == 0)
sum -= t;
else
sum += t;
}
System.out.println("Sum = " + sum);
}
void sumSeries() {
long sum = 0, term = 1;
for (int i = 1; i <= 20; i++) {
term *= i;
sum += term;
}
System.out.println("Sum=" + sum);
}
