    <p>I'm writing a word search program that scans in from a text file. The text file contains two integers (the dimensions of the puzzle, which in this case is 10x10), followed by the puzzle, followed by another integer (the amount of words to find), and finally the words to be found. I am trying to write the code so that the program will execute a for loop which will scan the next line in, then add each character in the string to the 2D array. However, the scanner continues seems to continue through the file and eventually "out of bounds" on the file, even though, according to the for loop, it should run no more than 10 times (the dimension of the puzzle is 10x10)</p> <p>Here is the problematic code:</p> <pre><code>Scanner scan = new Scanner(new File("puzzle.txt")); int rows = scan.nextInt(); int columns = scan.nextInt(); int [][] wordSearch = new int[rows][columns]; for (int i = 0; i &lt; rows; i++){ for (int j = 0; j &lt; columns; j++){ String temp = scan.nextLine(); for (int k = 0; k &lt; temp.length(); k++){ wordSearch[i][j] = temp.charAt(k); } } } </code></pre> <p>Here is the puzzle.txt:</p> <ul> <li>10 10</li> <li>WVERTICALL</li> <li>ROOAFFLSAB</li> <li>ACRILIATOA</li> <li>NDODKONWDC</li> <li>DRKESOODDK </li> <li>OEEPZEGLIW</li> <li>MSIIHOAERA</li> <li>ALRKRRIRER</li> <li>KODIDEDRCD</li> <li>HELWSLEUTH</li> <li>10</li> <li>WEEK</li> <li>FIND</li> <li>RANDOM</li> <li>SLEUTH</li> <li>BACKWARD</li> <li>VERTICAL</li> <li>DIAGONAL</li> <li>WIKIPEDIA</li> <li>HORIZONTAL</li> <li>WORDSEARCH</li> </ul>

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.
