Question

Write a java code to ask the user for a string, and assuming the user enters a string containing character "a", your java program must convert all "a" to "b" in the string so for example if user types : "AMAZON" , your program must convert it to "BMBZON"

the driver program must ask :

enter a string containing "a" or "A"

--------- (user enters string)

then it should say;

HERE IS YOUR NEW STRING

---------- (string with all a's converted to b.)

important : all a's should be b and even for capital letters (i.e. A to B).

Answer 1

Java Code

import java.util.*;

public class Main

{

     public static void main(String[] args)

     {

         

         Scanner input= new Scanner(System.in);

         System.out.println("enter a string containing \"a\" or \"A\"");

        String str = input.nextLine();

         String strupper = str.replace('A', 'B');// Replace all the capital letters 'A' characters with Uppercase 'B' characters.

        String resultstring=strupper.replace('a', 'b');// Replace all the lowercase letters 'a' characters with Uppercase 'b' characters.

                      

        System.out.println("HERE IS YOUR NEW STRING ");

        System.out.println(resultstring);

          }

}
