    <p>I have researched this topic for a while, but without much success. I did find the StringBuilder and it works wonders, but that's as far as I got. Here is how I got my hangman program to work like it should:</p> <pre><code> if(strGuess.equalsIgnoreCase("t")){ mainword.replace(0,1,"T"); gletters.append('T'); } else if(strGuess.equalsIgnoreCase("e")){ mainword.replace(1,2,"E"); gletters.append('E'); } else if(strGuess.equalsIgnoreCase("c")){ mainword.replace(2,3,"C"); gletters.append('C'); } else if(strGuess.equalsIgnoreCase("h")){ mainword.replace(3,4,"H"); gletters.append('H'); } else if(strGuess.equalsIgnoreCase("n")){ mainword.replace(4,5,"N"); gletters.append('N'); } else if(strGuess.equalsIgnoreCase("o")){ mainword.replace(5,6,"O"); mainword.replace(7,8,"O"); gletters.append('O'); } else if(strGuess.equalsIgnoreCase("l")){ mainword.replace(6,7,"L"); gletters.append('L'); } else if(strGuess.equalsIgnoreCase("g")){ mainword.replace(8,9,"G"); gletters.append('G'); } else if(strGuess.equalsIgnoreCase("y")){ mainword.replace(9,10,"Y"); gletters.append('Y'); } else{ JOptionPane.showMessageDialog(null, "Sorry, that wasn't in the word!"); errors++; gletters.append(strGuess.toUpperCase()); } SetMain = mainword.toString(); GuessedLetters = gletters.toString(); WordLabel.setText(SetMain); GuessedLabel.setText(GuessedLetters); GuessText.setText(null); GuessText.requestFocusInWindow(); </code></pre> <p>However, I can't do this for EVERY letter for EVERY word, so is there a simple and efficient way to do this? What I want is to have a loop of some sort so that I would only have to use it once for whatever word. So the word could be technology (like it is above) or apple or pickles or christmas or hello or whatever.</p> <p>I have tried using a for loop, and I feel the answer lies in that. And if someone could explain the charAt() method and how/where to use it, that'd be good. The closest I got to being more efficient is:</p> <pre><code>for(i = 0; i &lt; GuessWord.length(); i++) { if (GuessWord.charAt(i) == guess2) { mainword.replace(i,i,strGuess.toUpperCase()); } </code></pre> <p>So if you could use that as a basis and go off of it, like fix it? Or tell me something I haven't thought of.</p>

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.
