You may input abba and get answer it's evenly symmetric and aba is oddly symmetric.</p> <p>Please show me how:(</p> <p>Just two main things.</p> <p>first I want to know if it's oddly or evenly amount of letter(number of letter divided by 2,if it's ending with 0.5, it's oddly symmetric, if is an integer it's evenly symmetric.</p> <p>second I want to get (i.e 1=n,2=n-1,3=n-2...) position of the letter in the word to be the main idea of the execution.If there is a last letter in the oddly symmetric word, ignore the last remaining letter.</p> <p>I appreciate any headstart or idea:) Thanks!</p> <p>Thanks KDiTraglia, I made the code and compiled and here is what I put. I am not getting any further.</p> <p>Reported problem:</p> <pre><code>Exception in thread "main" java.lang.Error: Unresolved compilation problems: reverse cannot be resolved or is not a field reverse cannot be resolved or is not a field Syntax error, insert ") Statement" to complete IfStatement </code></pre> <p>This is what i got from, KDiTraglia's help</p> <pre><code> public class WordSymmetric { public static void main(String[] args) { String word = "abccdccba"; if ( (word.length() % 2) == 1 ) { System.out.println("They are oddly symmetric"); //odd } else { System.out.println("They are evenly symmetric"); //even } int halfLength = word.length() / 2; String firstHalf = word.substring(0, halfLength); String secondHalf = word.substring(halfLength, word.length()); System.out.println(secondHalf.reverse()); if (firstHalf.equals(secondHalf.reverse()) { System.out.println("They match"); //they match } } } </code></pre>

    1. CONo, you *haven't* got the code to compile. If you had, you wouldn't have an exception of "Unresolved compilation problems" would you? `String` doesn't have a `reverse` method.

    2. COI did and but then I found the code is not running. I am confused.

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.
