    <p>So I am using the following to read in a text file:</p> <pre><code>import java.io.File; import java.io.FileNotFoundException; import java.util.Scanner; String f = "file.txt"; Scanner in = new Scanner(new File(f)); while(in.hasNextLine()){ //code here to make a matrix from the data in the text file } </code></pre> <p>now this text file should create a matrix with 48927 rows (the number of lines in the text file). At the 196th row, the while loop breaks.</p> <p>It used to be the 198th row, then I stripped white space (not the ending line break) and it moved to 196</p> <p>I looked at both of these rows, and there is nothing differing them from the others!</p> <p><strong>Why is scanner not reading them as lines?</strong></p> <h1>rows</h1> <p>just to give you some inside on the file, here are what the rows look like (195-200):</p> <pre><code>CRUMBS BAKE SHOP&lt;split&gt;420&lt;split&gt;LEXINGTON AVENUE&lt;split&gt;10017&lt;split&gt;2122970500&lt;split&gt;2010-12-30 00:00:00&lt;split&gt;10.0&lt;split&gt;N&lt;split&gt;MANHATTAN&lt;split&gt;BAKERY FAITHY'S KITCHEN&lt;split&gt;3907&lt;split&gt;DYRE AVENUE&lt;split&gt;10466&lt;split&gt;7186550780&lt;split&gt;2010-12-03 00:00:00&lt;split&gt;22.0&lt;split&gt;N&lt;split&gt;THE BRONX&lt;split&gt;CARIBBEAN SIRUYEON&lt;split&gt;150-36&lt;split&gt;NORTHERN BOULEVARD&lt;split&gt;11354&lt;split&gt;7184616677&lt;split&gt;2013-05-07 00:00:00&lt;split&gt;60.0&lt;split&gt;N&lt;split&gt;QUEENS&lt;split&gt;CAFE, COFFEE, TEA MILON BANGLASESH &amp; INDIAN RESTAURANT&lt;split&gt;93&lt;split&gt;1 AVENUE&lt;split&gt;10003&lt;split&gt;2122284896&lt;split&gt;2013-02-20 00:00:00&lt;split&gt;19.0&lt;split&gt;B&lt;split&gt;BROOKLYN&lt;split&gt;BANGLADESHI HOLEY CREAM&lt;split&gt;796&lt;split&gt;9 AVENUE&lt;split&gt;10019&lt;split&gt;2122478400&lt;split&gt;2011-07-18 00:00:00&lt;split&gt;16.0&lt;split&gt;B&lt;split&gt;MANHATTAN&lt;split&gt;ICE CREAM, GELATO, YOGURT, ICES CHOP'T&lt;split&gt;1460&lt;split&gt;BROADWAY&lt;split&gt;10036&lt;split&gt;6465710601&lt;split&gt;2011-10-25 00:00:00&lt;split&gt;nan&lt;split&gt;A&lt;split&gt;MANHATTAN&lt;split&gt;SALADS </code></pre> <p>note: the commas in the last row is a common feature throughout the entire text file</p> <h1>error</h1> <p>if I let the while loop go until an error, at line 196 (the line it cannot recognize) I get this error:</p> <pre><code>Exception in thread "main" java.util.NoSuchElementException: No line found at java.util.Scanner.nextLine(Scanner.java:1516) </code></pre>

    1. CODo you have any breaks in the omitted code or your code does not read any further?

    3. COthe reason the loop stops is not because of an error nor because of my code, it is because `in.hasNextLine()` becomes `false` AKA the scanner believes there is not another line yet there are 48700 more lines...

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).
