    <p>I guess you've got this covered by now, but I was curious, so I made a shot at your classes, and commented my changes. Hopefully you, or someone else, can get some use of it :-]</p> <pre><code>// renamed from Hangman public class Main { public static void main(String[] args) { // removed need for JFrame as no GUI is actually used. Hangman hangman = new Hangman(); // starting a thread with the hangman runnable new Thread(hangman).start(); // main thread will end here, but the hangman thread will keep the program running. } } </code></pre> <p>Then the actual Hangman class:</p> <pre><code>import java.util.Arrays; import java.util.Scanner; // Renamed from HangmanPanel, changed from JPanel to Runnable since no GUI is shown. public class Hangman implements Runnable { // always use 7 lives, as this is the number of "hangman images" in reduceLives() private int lives = 7; private char[] hiddenWord; private char[] aOfWord; // I'm guessing that at some point you will use these randomly? private String[] words = { "ADA", "COBOL", "LOGO", "BASIC", "PROLOG", "UBUNTU", "UHURU" }; @Override public void run() { // This is the new Try-With-Resources in Java 7. // If you don't have Java 7, just change the // try ( Scanner scan = new Scanner(System.in) ) { // to // try { // Scanner scan = new Scanner(System.in); try ( Scanner scan = new Scanner(System.in) ) { System.out.println("Enter the word to be searched: "); String inputw = scan.nextLine(); aOfWord = inputw.toCharArray(); hiddenWord = new char[aOfWord.length]; // nice method for filling an array.

    1. COThanks. It is helpful. I couldn't quite figure it out for my assignment, so I just handed it in to get some credit. But it's nice to see how it works. I copied and pasted this into my editor. I'll definitely use this as a reference in the future. Thanks.

Querying!

 
Guidance
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).
