    <p>I've written working on a java applet, which seems to be opening sun.applet.AppletViewer when it is running. I'm using the acm libraries for the Stanford Engineering Everywhere Hangman assignment. The problem I'm having doesn't seem to be with the code, unless I've not done some implementation I should've. Basicly Applet Viewer is hanging just saying "starting applet..." and the program isn't running. I've not encountered this problem before, so I figured I'ld ask here in case anyone has encountered a problem like this before. I guess it might be the default exception case that is getting thrown, but I'm not getting an error message so I doubt it.</p> <p>I think the code should be working, but I'll post it in case there is something obvious I've left out at this point. I'm not quite finished with the assignment, but I'm fairly confident it would work if I wasn't having this problem.</p> <p>Hangman.java</p> <pre><code>import acm.graphics.*; import acm.program.*; import acm.util.*; import java.awt.*; import java.io.*; public class Hangman extends ConsoleProgram { //private static final int NUM_GUESSES=8; /*new instance of HangmanLexicon.java */ private HangmanLexicon hangLex; private HangmanCanvas canvas; /*new random generator to get indexes of words in hangLex*/ //private RandomGenerator rgen = RandomGenerator.getInstance(); /*Stores word that use is trying to guess*/ private String hidden=""; /*Displayed version of hidden*/ private String displayHidden = ""; /*prompt for player to enter their guess, which gets stored * as a string*/ private String guess = readLine("Your guess: "); /*counts down until user has no more guesses*/ private int guessCounter = 8; private String repeat = readLine("Play again?

    2. CO1. I don't know if it's using html. It should just run in a separate window, which I agree is somewhat unconventional for an applet, but it's for a class, so I don't think they'd be using html. 2. I just wonderring if there's any explanation for the hanging

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).
