5. Design a class to overload a function Joystring() as follows:
(i) 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='0'
Output : “TECHNOLOGY”
(ii) 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 ="Cloud computing means Internet based computing"
Output: First index: 5
Last index: 36
(iii) 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)

Answer:
public class KboatStringOverload
{
public void joystring(String s, char ch1, char ch2) {
String newStr = s.replace(ch1, ch2);
System.out.println(newStr);
}
public void joystring(String s) {
int f = s.indexOf(' ');
int l = s.lastIndexOf(' ');
System.out.println("First index: " + f);
System.out.println("Last index: " + l);
}
public void joystring(String s1, String s2) {
String newStr = s1.concat(" ").concat(s2);
System.out.println(newStr);
}
public static void main(String args[]) {
KboatStringOverload obj = new KboatStringOverload();
obj.joystring("TECHNALAGY", 'A', 'O');
obj.joystring("Cloud computing means Internet based computing");
obj.joystring("COMMON WEALTH", "GAMES");
}
}
