    <p>I have implemented it in a different way, but it works as you expect, only for uppercase as in your example:</p> <pre><code>import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.util.Arrays; import java.util.List; public class WhileLoopIssue { public static void main( String[] args ) throws IOException { BufferedReader myInput = new BufferedReader( new InputStreamReader( System.in ) );// Buffered Reader reads the // number inputed final List&lt;String&gt; letterList = Arrays.asList( "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z" ); System.out.println( "Enter a phrase: " ); String phrase = myInput.readLine(); final String[] letters = phrase.split( "" ); // Split input phrase final StringBuffer buffer = new StringBuffer(); // Variable to save letters. Could be a String as well. for ( int i = 0; i &lt; letters.length; i++ ) { final int letterIndex = letterList.indexOf( letters[i] ); // Get the numeric value of the letter if ( letterIndex &lt; 0 ) // Skip iteration if not found. Maybe a lowercase, or an empty String continue; final int nextLetterIndex = 13 + letterIndex; // Actual value of the letter + 13 if ( nextLetterIndex &gt; letterList.size() ) { buffer.append( nextLetterIndex % letterList.size() ); // Actual value greater than the total number of letters in the alphabet, so we get the modulus for the letter } else { buffer.append( letterList.get( nextLetterIndex ) ); // Letter in the range, get it } } System.out.println( buffer.toString() ); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
