    <h2>Guava Sample Usage</h2> <p>Yes, using Guava is a great idea, especially for simple tasks as <a href="http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/io/Files.html#toString(java.io.File,%20java.nio.charset.Charset)" rel="noreferrer">reading a file</a>:</p> <pre><code>String contents = Files.toString(file, Charsets.UTF_8) </code></pre> <p>when compared to plain java versions like this:</p> <pre><code>BufferedReader in = null; StringBuilder sb = new StringBuilder(); try { in = new BufferedReader(new FileReader(file)); String str; while ((str = in.readLine()) != null) { sb.append(str).append('\n'); } } catch (IOException e) { // do something here } finally{ // and this should also be in a try / catch block if(in!=null)in.close(); } return sb.toString(); </code></pre> <p>(But actually you need to have developed Java for years to really appreciate the easiness IMHO.)</p> <h2>Configuring Eclipse to use Guava</h2> <p>The easiest way to deal with such a library in Eclipse is to create a User library and add the user library to your project (right click project: <code>Build Path -&gt; Add Library -&gt; User Library</code>).</p> <p>Here is a short guide to generating a User Library:</p> <ol> <li>Open the menu entry <code>Preferences -&gt; Java -&gt; Build Path -&gt; User Libraries</code></li> <li>Press <code>New...</code>, enter a name (e.g. 'Guava')</li> <li>Press <code>Add JARs...</code> and search for the JAR files you downloaded<br> (Unzip the <a href="http://guava-libraries.googlecode.com/files/guava-r07.zip" rel="noreferrer">Guava archive</a> beforehand, inside you'll find the file <code>guava-r07.jar</code>. Select that in this dialog, preferably after moving it to a more desirable location)</li> <li>Now select <code>Source Attachment -&gt; Edit...</code>, and find the path to the file <code>guava-src-r07</code>.</li> <li>If you want to, you can repeat this process for the JavaDoc location, pointing it to the <code>javadoc</code> folder from the guava distribution</li> <li>Press <code>OK</code>.</li> </ol> <p>Now you should be all set, you can select the user library and add it to a project of your choice.</p> <h2>Using Maven</h2> <p>For completeness: being an advocate of dependency management with maven I would of course suggest to manage project dependencies with <a href="http://maven.apache.org/" rel="noreferrer">maven</a> and <a href="http://m2eclipse.sonatype.org/" rel="noreferrer">m2eclipse</a> instead of with user libraries.</p>

    2. COThis question is not answered. After [Window ->]Preferences -> Java -> Build Path -> User Libraries, there are two options: New and Import. Import is looking for something like .userlibraries, which the Guava download doesn't seem to include. If I choose "New" it lets me enter the name of my "new library" but I don't know how to make that actually *be* a library. The help file doesn't tell me either.

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).
