    <p>If you want to split the <code>String</code> at the <code>/</code> character, the <a href="http://java.sun.com/javase/6/docs/api/java/lang/String.html#split(java.lang.String)" rel="noreferrer"><code>String.split</code></a> method will work:</p> <p>For example:</p> <pre><code>String s = "prefix/dir1/dir2/dir3/dir4"; String[] tokens = s.split("/"); for (String t : tokens) System.out.println(t); </code></pre> <p>Output</p> <pre><code>prefix dir1 dir2 dir3 dir4 </code></pre> <p><strong>Edit</strong></p> <p>Case with a <code>/</code> in the prefix, and we know what the prefix is:</p> <pre><code>String s = "slash/prefix/dir1/dir2/dir3/dir4"; String prefix = "slash/prefix/"; String noPrefixStr = s.substring(s.indexOf(prefix) + prefix.length()); String[] tokens = noPrefixStr.split("/"); for (String t : tokens) System.out.println(t); </code></pre> <p>The substring without the prefix <code>"slash/prefix/"</code> is made by the <a href="http://java.sun.com/javase/6/docs/api/java/lang/String.html#substring(int)" rel="noreferrer"><code>substring</code></a> method. That <code>String</code> is then run through <code>split</code>.</p> <p>Output:</p> <pre><code>dir1 dir2 dir3 dir4 </code></pre> <p><strong>Edit again</strong></p> <p>If this <code>String</code> is actually dealing with file paths, using the <a href="http://java.sun.com/javase/6/docs/api/java/io/File.html" rel="noreferrer"><code>File</code></a> class is probably more preferable than using string manipulations. Classes like <code>File</code> which already take into account all the intricacies of dealing with file paths is going to be more robust.</p>

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.

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