(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:

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);
}
}Output

Define a class to overload the method perform as follows:
double perform (double r, double h) — to calculate and return the value of curved surface area of cone
void perform (int r, int c) — Use NESTED FOR LOOP to generate the following format
r = 4, c = 5
output
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5void perform (int m, int n, char ch) — to print the quotient of the division of m and n if ch is Q else print the remainder of the division of m and n if ch is R
