    <p>I have a scanner to read a .csv file.<br> The file is in the same directory and the .java files, however it can't seem to find the file.<br> What can I do to fix this issue?</p> <pre><code>Scanner scanner = new Scanner(new File("database.csv")); </code></pre> <p>Edit: Sorry forgot to mention that I need to use the Scanner package because in the next line I use a delimiter.</p> <pre><code>Scanner scanner = new Scanner(new File("database.csv")); scanner.useDelimiter(",|\r|\n"); </code></pre> <p>Also I am working in IntelliJIDEA</p> <p>So here is the full code</p> <pre><code>import java.io.File; import java.io.FileNotFoundException; import java.util.Scanner; import java.util.*; public class City { public String name; // The name of the city public String cont; // The continent of the city public int relTime; // Time relative to Hobart (eg. -14 for New York) public boolean dst; // Does the city use DST? public boolean valid; // Does the city exist?

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).
