    <p>Similar questions deal with files on the <code>C:</code> drive, where hardcoding the file path is an acceptable answer. This application is mobile, and hardcoding the file path is not practical.</p> <p>I am trying to import a text file via scanner, that contains a list of strings, 15 characters each, 1 per line. LOTS of lines. The file name is <code>a.txt</code>.</p> <p>I call it using</p> <pre><code>File data = new File("a.txt"); Scanner in = new Scanner(data); </code></pre> <p>repeated the lines below with "b.txt", using different Object names.</p> <p>However, when I build the program, I get this error log (using Jcreator IDE):</p> <pre><code>--------------------Configuration: &lt;Default&gt;-------------------- E:\Simple Encryption\Simple_Encryption.java:17: unreported exception java.io.FileNotFoundException; must be caught or declared to be thrown Scanner in = new Scanner(data); ^ E:\Simple Encryption\Simple_Encryption.java:18: unreported exception java.io.FileNotFoundException; must be caught or declared to be thrown Scanner numsIn = new Scanner(nums); ^ 2 errors Process completed. </code></pre> <p>The program is in the folder <code>E:/Simple Encryption/</code>, which contains the following files and folders:</p> <ul> <li>Simple_Encryption.java</li> <li>Simple_Encryption.class</li> <li>lock.png (unused)</li> <li>a.txt</li> <li>b.txt (same error as <code>a.txt</code> on import, just one line below)</li> <li>/images (folder, contains icon.png)</li> </ul> <p>There is nothing else in the folder. I cannot hardcode the file path because on different computers, it has different drive names, and will be distributed under different folders later. (Here (School), it's on the <code>E:</code> drive, at home it's the <code>J:</code>drive, and at work it's on the <code>G:</code> drive.)</p> <p>Although I have gotten help from existing errors, I need to import this on the program startup, and not just skip it. The file exists in it's current form, and the program cannot function without it.</p> <p>What is causing this error? And what can I do to prevent this?</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.
