Answer 1

Answer:

Question 26

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

You are very cute

Answer 2

Answer:

import java.util.*;

class Sample

{

   static void print(int x , int y)

   {

   int difference = (x*x) - (y*y);

   System.out.println("The difference of the squares of " + x  + " and " + y + " is " + difference);  

   }

}

public class Main

{

public static void main(String[] args) {

 int i = 9;

 int j = 8;

 Sample.print(i , j);

}

}
