    <p>I have made a basic hangman game on Netbeans, and the way it works is a user clicks one of the 26 buttons (one for each letter of the alphabet) and that letter is tested in the word. The main problem I'm having is getting the letter to be tested.</p> <pre><code> //array holding all buttons JButton[] alphabet = {AButton, BButton, CButton, DButton, EButton, FButton, GButton, HButton, IButton, JButton, KButton, LButton, MButton, NButton, OButton, PButton, QButton, RButton, SButton, TButton, UButton, VButton, WButton, XButton, YButton, ZButton}; //getting the current letter(need something in place of the 0) String currentLetter = (alphabet[0].getLabel()); //replace underscores with letters as they are guessed for (int i = 0; i &lt; 1; i++) { secretWord = secretWord + currentLetter.charAt(0); foundWord = words[randValue].replaceAll("[^" + secretWord + "]", "_ "); } </code></pre> <p>I read somewhere that using a button array is what I had to do, so I put it in but it didn't work. Also, I read that an ActionListener was needed for the program to read what letter it is. Previous tries I have used were:</p> <pre><code>currentLetter = AButton.getText(); currentLetter = AButton.getLabel(); </code></pre> <p>but sadly to no avail. So keep in mind that I am using Netbeans and I'm new-ish to Java, so no big elaborate hard stuff, keep it simple. Thanks:)</p> <p>EDIT:</p> <pre><code> private void AButtonActionPerformed(java.awt.event.ActionEvent evt) { DoButton.doClick(); } private void DoButtonActionPerformed(java.awt.event.ActionEvent evt) { JButton button = (JButton) evt.getSource(); String currentLetter = button.getText(); //replace underscores with letters as they are guessed for (int i = 0; i &lt; 1; i++) { secretWord = secretWord + currentLetter.charAt(0); foundWord = words[0].replaceAll("[^" + secretWord + "]", "_ ");

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.
