Answer to Monday's Encoded Line Question

The question on Monday was concerned with writing a program to decode this first line from a book by Iain Banks:

xv fpu vot ipk nk chpwindvoth tqeyditi

which turns out to be from The Crow Road:

it was the day my grandmother exploded

The program needed to take an encoded line from a user, use a combination of a normal for loop and switch statement, and finally display the result. I have to say that even though it was somewhat unexpected, the solution in c++ was most welcome. Well done to everyone who decoded the line.

Here's my version:

import java.util.Scanner;

public class Decoder {

  public static void main(String[] args) {

    //Get the input from the user
    Scanner input = new Scanner(System.in);
    System.out.println("Enter in text to be decoded: ");
    String codedText = input.nextLine();

    //Make sure the line is in lowercase
    codedText = codedText.toLowerCase();

    //Split the string into an array of chars
    char letters[] = codedText.toCharArray();

    //Decode the line of text
    char decodedLetter = ' ';
    for (int i=0; i     {
      switch(letters[i])
      {
        case 'a':
          decodedLetter = 'z';
          break;
        case 'b':
          decodedLetter = 'j';
          break;
        case 'c':
          decodedLetter = 'g';
          break;
        case 'd':
          decodedLetter = 'o';
          break;
        case 'e':
          decodedLetter = 'p';
          break;
        case 'f':
          decodedLetter = 'w';
          break;
        case 'g':
          decodedLetter = 'f';
          break;
        case 'h':
          decodedLetter = 'r';
          break;
        case 'i':
          decodedLetter = 'd';
          break;
        case 'j':
          decodedLetter = 'c';
          break;
        case 'k':
          decodedLetter = 'y';
          break;
        case 'l':
          decodedLetter = 'u';
          break;
        case 'm':
          decodedLetter = 'q';
          break;
        case 'n':
          decodedLetter = 'm';
          break;
        case 'o':
          decodedLetter = 'h';
          break;
        case 'p':
          decodedLetter = 'a';
          break;
        case 'q':
          decodedLetter = 'x';
          break;
        case 'r':
          decodedLetter = 'b';
          break;
        case 's':
          decodedLetter = 'k';
          break;
        case 't':
          decodedLetter = 'e';
          break;
        case 'u':
          decodedLetter = 's';
          break;
        case 'v':
          decodedLetter = 't';
          break;
        case 'w':
          decodedLetter = 'n';
          break;
        case 'x':
          decodedLetter = 'i';
          break;
        case 'y':
          decodedLetter = 'l';
          break;
        case 'z':
          decodedLetter = 'v';
          break;
        default:
          decodedLetter = letters[i];
          break;
      }
      System.out.print(decodedLetter);
    }
  }
}
