    <p>I'm trying to start working with Java, but so far haven't been able to get it on my machine properly. I'd really like to be able to compile from command line. After following the instructions <a href="http://ubuntuforums.org/showthread.php?t=332674" rel="nofollow noreferrer">here</a> with no errors I can't compile with <code>javac</code>. Here's what I have so far:</p> <p>When I enter:</p> <pre><code>$ java -version </code></pre> <p>I get:</p> <pre><code>java version "1.6.0_16" Java(TM) SE Runtime Environment (build 1.6.0_16-b01) Java HotSpot(TM) Server VM (build 14.2-b01, mixed mode) </code></pre> <p>When I run:</p> <pre><code>$ sudo apt-get install sun-java6-jdk </code></pre> <p>I get:</p> <pre><code>~$ sudo apt-get install sun-java6-jdk Reading package lists...

    1. COWhat do you mean by "can't compile"? Can't find the program javac? Errors compiling?

    2. COYou have the Java runtime installed. You probably do not have the development tools installed (where the compiler lives)

    3. COLooks like, at that point of time, the particular mirror you are using couldn't be connected to. The problem could be at either end. Did you try it again? It definitely looks like a problem with the 'apt-get update'.

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).
