## Overview

**`isRegularFile()`** is a #key# static: the methods in Java that can be called without creating an object of the class #key# method of the `FileUtils` class that is used to check whether or not a given file is a regular file. 

**Regular files** are neither directories nor special files. They are primarily used to store text or binary data.

#  
## 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:

---

``` xml
<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](https://mvnrepository.com/artifact/commons-io/commons-io).

You can import the `FileUtils` class as follows:

---

```
import org.apache.commons.io.FileUtils;
```

# 
#  Syntax


``` java
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.

##
## Return value

This method returns true if the file is a regular file. Otherwise, it returns false.


import org.apache.commons.io.FileUtils;

import java.io.File;

public class Main{

    public static void main(String[] args) {
      // Example 1
        String filePath = "1.txt";
        File file = new File(filePath);
        System.out.println("The output of FileUtils.isRegularFile(1.txt) is - " + FileUtils.isRegularFile(file));

      // Example 2
        filePath = "2.txt";
        file = new File(filePath);
        System.out.println("The output of FileUtils.isRegularFile(2.txt) is - " + FileUtils.isRegularFile(file));
    }
}

#    
## Explanation
### Example 1 

* `file: 1.txt`

The method returns true because the file is available and is a regular file.
    
  
### Example 2 

* `file: 2.txt`

The method returns false because the file is not available.

# 
## Output

The output of the code is as follows:



```xml
The output of FileUtils.isRegularFile(1.txt) is - true
The output of FileUtils.isRegularFile(2.txt) is - false
```
