Answer to Uncoded Line Question

On Monday the question was to write a program to calculate what the encoded line would be for:

it was a dark and stormy night

which encodes into:

xv fpu p iphs pwi uvdhnk wxcov

The program needed to take in a line of text from the user, use a combination of a for-each loop and switch statement, and finally display the encoded line. The goal was to highlight how useful the for-each loop is when you need to iterate through an entire collection (e.g., a char array). Here's my version:

import java.util.Scanner;

public class Encoder {

  public static void main(String[] args) {

     Scanner input = new Scanner(System.in);

     System.out.println("Enter in text to be encoded: ");
     String codedText = input.nextLine();

     codedText = codedText.toLowerCase();
     char letters[] = codedText.toCharArray();

     char encodedletter = ' ';
     for (char uncodedLetter:letters)
     {
       switch(uncodedLetter)
       {
         case 'z':
           encodedletter = 'a';
           break;
         case 'j':
           encodedletter = 'b';
           break;
         case 'g':
           encodedletter = 'c';
           break;
         case 'o':
           encodedletter = 'd';
           break;
         case 'p':
           encodedletter = 'e';
           break;
         case 'w':
           encodedletter = 'f';
           break;
         case 'f':
           encodedletter = 'g';
           break;
         case 'r':
           encodedletter = 'h';
           break;
         case 'd':
           encodedletter = 'i';
           break;
         case 'c':
           encodedletter = 'j';
           break;
         case 'y':
           encodedletter = 'k';
           break;
         case 'u':
           encodedletter = 'l';
           break;
         case 'q':
           encodedletter = 'm';
           break;
         case 'm':
           encodedletter = 'n';
           break;
         case 'h':
           encodedletter = 'o';
           break;
         case 'a':
           encodedletter = 'p';
           break;
         case 'x':
           encodedletter = 'q';
           break;
         case 'b':
           encodedletter = 'r';
           break;
         case 'k':
           encodedletter = 's';
           break;
         case 'e':
           encodedletter = 't';
           break;
         case 's':
           encodedletter = 'u';
           break;
         case 't':
           encodedletter = 'v';
           break;
         case 'n':
           encodedletter = 'w';
           break;
         case 'i':
           encodedletter = 'x';
           break;
         case 'l':
           encodedletter = 'y';
           break;
         case 'v':
           encodedletter = 'z';
           break;
         default:
           encodedletter = uncodedLetter;
           break;
       }
       System.out.print(encodedletter);
     }
   }
}
