## Overview

**`getUserName()`** is a #key# static: describes the methods in Java that can be called without creating an object of the class #key# method of the `SystemUtils` class which is used to return the user name.

## How to import `SystemUtils`

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

---

``` xml
<dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-lang3</artifactId>
            <version>3.12.0</version>
</dependency>
```

---

> For other versions of the `commons-lang` package, refer to the [Maven Repository](https://mvnrepository.com/artifact/org.apache.commons/commons-lang3).

You can import the `SystemUtils` class as follows:

```

#

        System.out.printf("The output of SystemUtils.getUserName() is '%s'.", userName);
    }
}

In the above code, we print the user name returned by the `getUserName()` method.
