12,086 PointsHow can I deploy my Hangman Java game using IntelliJ IDEA?
I would like to share my Hangman game made in the Java course on my personal web site. Can someone point me towards a tutorial that can guide me through the process?
I'm looking for something like this, but for IntelliJ IDEA: http://www.oxfordmathcenter.com/drupal7/node/37

The real issue is that Oracle Java's security policy forces anyone viewing the applet through a browser to manually add an exception to allow it to run. Unless your willing to shell out $$$$ for a signing certificate.

56,413 PointsThe only parts really specific to an IDE is adding the acm.jar file to the project creating your .jar file and the instructions from the IDEA docs are here https://www.jetbrains.com/idea/help/configuring-module-dependencies-and-libraries.html#d1265574e216 and here https://www.jetbrains.com/idea/help/packaging-a-module-into-a-jar-file.html

56,413 PointsWould you mind if I had a few suggestions? That button code isn't particularly DRY. Usually if you have a lot of buttons or other widgets it's better to have one listener and have the listener find out which button was pressed. An event listener like this is usually passed the "who, what, when", or at least the "who".
private ActionListener mLetterListener = new ActionListener() {
public void actionPerformed(ActionEvent e) {
JButton buttonClicked = (JButton) e.getSource();
char letter = buttonClicked.getText().charAt(0);
buttonClicked.getParent().remove(buttonClicked);
checkLetter(letter);
}
};
Also since you have 26 individual buttons that are each 1. added to a panel, 2. given a listener, you can replace all that with a for loop.
public static final String ALPHABET = "abcdefghijklmnopqrstuvwxyz";
// ...
int length = ALPHABET.length();
for (int i = 0; i < length; i++) {
JButton button = new JButton(ALPHABET.substring(i,i+1));
button.addActionListener(mLetterListener);
if(i < length/2) { // add the first half of the alphabet to panel 1
p1.add(button);
} else { // and the second half to panel 2
p2.add(button);
}
}
