    <p><strong>Short answer</strong>: No, you have to code it.</p> <p><strong>Long answer</strong>: List and Set both have a method for obtaining an <a href="http://download.oracle.com/javase/1.5.0/docs/api/java/util/Iterator.html" rel="nofollow">Iterator</a> (there are a few other collection classes, but probably not what your looking for). The List and Set interfaces are a part of the <a href="http://download.oracle.com/javase/1.5.0/docs/guide/collections/index.html" rel="nofollow">Collections Framework</a> which only allow for adding/removing/iterating Objects like Character or Integer (not primitives like char or int). There is a feature in <a href="http://java.sun.com/developer/technicalArticles/releases/j2se15/" rel="nofollow">Java 1.5 called auto-boxing</a> that will hide this primitive to Object conversion but I don't recommend it and it won't provide what you want in this case.</p> <p>An alternative would be to wrap the String in a class of your own that </p> <pre><code>implements Iterator&lt;Character&gt; </code></pre> <p>but that might be more work than it is worth.</p> <p>Here is a code snippet for doing what you want:</p> <pre><code>String s = ""; List&lt;Character&gt; list = new ArrayList&lt;Character&gt;(s.length()); for (int i = 0; i &lt; s.length(); i++) { // note that Character.valueOf() is preferred to new Character() // you can omit the Character.valueOf() method // and Java 1.5+ will auto-box the primitive into an Object list.add(Character.valueOf(s.charAt(i))); } Iterator&lt;Character&gt; iterator = list.iterator(); </code></pre>

    1. CO`List` and `Set` are **not** implementing `Iterator`.

    2. COThey are implementing the `Iterable` interface (which provides a `iterator()` function which returns an `Iterator`) so that is ok. But your code is inefficient because it creates a full copy of the string.

    3. CO@Willi, You are correct, the List and Set interfaces are subinterfaces of Collection which contains the .interator() method. If you look closely this is accomplished by extending abstract classes containing private subclasses that indeed implement Iterator, which iterates over the data within the List or Set. I should have stated that both List and Set provide a method for obtaining an Iterator.

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.
