## Code example


# create file names
fn1 = "main.rb"
fn2 = "test.txt"
fn3 = "nothing"
fn4 = "fake.txt"
fn5 = "empty.txt"

# check if files exists
puts File.exists?(fn1)
puts File.exists?(fn2)
puts File.exists?(fn3)
puts File.exists?(fn4)

#  
## Explanation
* **Lines 1–2**: We create a file called `text.txt` along with our source code file `main.rb`.
* **Lines 2–6**: We initialize the names of the files.
* **Lines 9–12**: We use the `file?()` method to check if the names of the files exist. Next, we print the results to the console.
