Design a class to overload a method series( ) as follows:
- double series(double n) with one double argument and returns the sum of the series.
sum = (1/1) + (1/2) + (1/3) + ………. + (1/n) - double series(double a, double n) with two double arguments and returns the sum of the series.
sum = (1/a2) + (4/a5) + (7/a8) + (10/a11) + ………. to n terms

public class KboatSeries
{
double series(double n) {
double sum = 0;
for (int i = 1; i <= n; i++) {
double term = 1.0 / i;
sum += term;
}
return sum;
}
double series(double a, double n) {
double sum = 0;
int x = 1;
for (int i = 1; i <= n; i++) {
int e = x + 1;
double term = x / Math.pow(a, e);
sum += term;
x += 3;
}
return sum;
}
public static void main(String args[]) {
KboatSeries obj = new KboatSeries();
System.out.println("First series sum = " + obj.series(5));
System.out.println("Second series sum = " + obj.series(3, 8));

Design a class overloading a method calculate() as follows:
- void calculate(int m, char ch) with one integer argument and one character argument. It checks whether the integer argument is divisible by 7 or not, if ch is 's', otherwise, it checks whether the last digit of the integer argument is 7 or not.
- void calculate(int a, int b, char ch) with two integer arguments and one character argument. It displays the greater of integer arguments if ch is 'g' otherwise, it displays the smaller of integer arguments.
Design a class to overload a method compare( ) as follows:
- void compare(int, int) — to compare two integers values and print the greater of the two integers.
- void compare(char, char) — to compare the numeric value of two characters and print with the higher numeric value.
- void compare(String, String) — to compare the length of the two strings and print the longer of the two.
