    <p>I'd argue that we can do much better than that... why aren't the guaranteed-to-be-available charsets accessible directly? <code>Charset.UTF8</code> should be a reference to the <code>Charset</code>, not the name as a string. That way we wouldn't have to handle <code>UnsupportedEncodingException</code> all over the place.</p> <p>Mind you, I also think that .NET chose a better strategy by defaulting to UTF-8 everywhere. It then screwed up by naming the "operating system default" encoding property simply <code>Encoding.Default</code> - which <em>isn't</em> the default within .NET itself :(</p> <p>Back to ranting about Java's charset support - why isn't there a constructor for <code>FileWriter</code>/<code>FileReader</code> which takes a <code>Charset</code>? Basically those are almost useless classes due to that restriction - you almost always need an <code>InputStreamReader</code> around a <code>FileInputStream</code>or the equivalent for output :(</p> <p>Nurse, nurse - where's my medicine?</p> <p>EDIT: It occurs to me that this hasn't really answered the question. The real answer is presumably either "nobody involved thought of it" or "somebody involved thought it was a bad idea." I would strongly suggest that in-house utility classes providing the names or charsets avoid duplication around the codebase... Or you could just use <a href="https://github.com/google/guava/blob/master/guava/src/com/google/common/base/Charsets.java" rel="nofollow noreferrer">the one that we used at Google when this answer was first written</a>. (Note that as of Java 7, you'd just use <a href="https://docs.oracle.com/javase/10/docs/api/java/nio/charset/StandardCharsets.html" rel="nofollow noreferrer"><code>StandardCharsets</code></a> instead.)</p>

    1. CO+1. But as a method rather than a field so as to allow lazy loading (okay, you are probably going to want UTF-8, but there are a few other charsets about and you might want similar facilities for them). Unfortunately this doesn't seem to be very popular with those making the decisions.

    2. COI'd be happy enough with a method, although I hope that eagerly loading those very few charsets wouldn't be a significant cost.

    3. COWe're on a crusade to stop eager class loading. / Just did a search of a JDK for "UTF-8". Found 270 match(es) in 165 file(s). Although a lot of that is in old Apache junk (I believe contributed by my team).

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.
