## Overview
The **`absolute_path()` method** of the `File` class in Ruby converts the path-name of a file to an absolute path-name. 

## Syntax
```ruby
File.absolute_path(path_name)
```
## Parameters
**`path_name`**: This is the `path-name` of the file. It is the relative path of the file whose starting point or absolute file path we want to get.
## Return value
The absolute file name of  `path_name` is returned.

## Code example

# get path_names
pn1 = "test1.txt";
pn2 = "test2.txt";

# get and print absolute path names
puts File.absolute_path(pn1)
puts File.absolute_path(pn2)

## Explanation
* We create two files: `test1.txt` and `test2.txt`.
* **Lines 2 to 3**: We get the `path-names` of the files whose absolute file paths we need.
* **Lines 6 to 7**: The `absolute_path()` is invoked to get the absolute paths of the files. Then, we print the results to the console.
