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.

public class KboatCompare
{
public void compare(int a, int b) {
if (a > b) {
System.out.println(a);
}
else {

Design a class to overload the method display(…..) as follows:
- void display(int num) — checks and prints whether the number is a perfect square or not.
- void display(String str, char ch) — checks and prints if the word str contains the letter ch or not.
- void display(String str) — checks and prints the number of special characters present in the word str.
Write a suitable main( ) function.
Design a class overloading and a method display( ) as follows:
- void display(String str, int p) with one String argument and one integer argument. It displays all the uppercase characters if 'p' is 1 (one) otherwise, it displays all the lowercase characters.
- void display(String str, char chr) with one String argument and one character argument. It displays all the vowels if chr is 'v' otherwise, it displays all the alphabets.
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 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
- double series(double n) with one double argument and returns the sum of the series.
