Explanation / Answer

Hi, Please find my implementation.

Please let me know in case of any issue.

import java.util.Scanner;

public class StringTesting {

   public static void main(String[] args) {

      

       String refStr;

       StringBuilder refBuilder;

      

       Scanner keyboard;

      

       int unicode;

      

       keyboard = new Scanner(System.in);

      

       System.out.print("Enter a string: ");

       refStr = keyboard.nextLine();

      

       refBuilder = new StringBuilder(refStr);

      

      

       for(int i=0; i<refBuilder.length(); i++){

           unicode = refBuilder.charAt(i);

           unicode = unicode + 1;

           refBuilder.setCharAt(i, (char)unicode);

       }

      

       System.out.println("String: "+refStr);

       System.out.println("String bulder: "+refBuilder);

      

      

      

   }

}

/*

Sample run:

Enter a string: sample

String: sample

String bulder: tbnqmf

*/
