Design a class to overload a function num_calc() as follows:
- void num_calc(int mini, char ch) with one integer argument and one character argument, computes the square of integer argument if choice ch is 's' otherwise finds its cube.
- void num_calc (int a, int b, char ch) with two integer arguments and one character argument. It computes the product of integer arguments if ch is 'p' else adds the integers.
- void num_calc (String s1, String s2) with two string arguments, which prints whether the strings are equal or not.

Design a class to overload a function Joystring( ) as follows:
- void Joystring(String s, char ch1, char ch2) with one string argument and two character arguments that replaces the character argument ch1 with the character argument ch2 in the given String s and prints the new string.
Example:
Input value of s = "TECHNALAGY"
ch1 = 'A'
ch2 = 'O'
Output: "TECHNOLOGY" - void Joystring(String s) with one string argument that prints the position of the first space and the last space of the given String s.
Example:
Input value of s = "Cloud computing means Internet based computing"
Output:
First index: 5
Last Index: 36 - void Joystring(String s1, String s2) with two string arguments that combines the two strings with a space between them and prints the resultant string.
Example:
Input value of s1 = "COMMON WEALTH"
Input value of s2 = "GAMES"
Output: COMMON WEALTH GAMES
(Use library functions)
- void Joystring(String s, char ch1, char ch2) with one string argument and two character arguments that replaces the character argument ch1 with the character argument ch2 in the given String s and prints the new string.
Design a class to overload a function compare( ) as follows:
- void compare(int, int) - to compare two integer values and print the greater of the two integers.
- void compare(char, char) - to compare the numeric value of two characters with higher numeric value.
- void compare(String, String) - to compare the length of the two strings and print the longer of the two.
Design a class to overload a function check( ) as follows:
void check (String str , char ch ) — to find and print the frequency of a character in a string.
Example:

Output:
number of s present is = 3void check(String s1) — to display only vowels from string s1, after converting it to lower case.
Example:
Input:
s1 ="computer"
Output : o u e
