What is FileUtils.isRegularFile() in Java?

How to import `FileUtils`

The definition of FileUtils can be found in the Apache Commons IO package, which we can add to the Maven project by adding the following dependency to the pom.xml file:

<dependency>
            <groupId>commons-io</groupId>
            <artifactId>commons-io</artifactId>
            <version>2.11.0</version>
</dependency>

For other versions of the commons-io package, refer to the Maven Repository.

You can import the FileUtils class as follows:

import org.apache.commons.io.FileUtils;

Syntax

public static boolean isRegularFile(final File file, final LinkOption... options)

Parameters

final File file: The file to check.
final LinkOption... options: Options that indicate how symbolic links are handled.
