Groovy 5 adds the extension methods getExtension and getBaseName to the File and Path classes.
You can invoke them as properties for a File and Path objects.
Also the asBoolean method is added.
This mean you can use a File or Path instance in a boolean context.
If the underlying file exists true is returned and false otherwise.
The following example shows how to use the new extension methods for the File class:
def file = new File("sample.txt")
assert file.extension == 'txt'
assert file.baseName == 'sample'
assert !file // File doesn't exist.
// Create file by writing content.
file.write("Some content")
assert file // File does exist now.
The same extension methods are added to the Path class and the following example shows their usage:
import java.nio.file.Path
def path = Path.of("sample.text")
assert path.extension == 'text'
assert path.baseName == 'sample'
assert !path // Path does not exist.
// Create path by setting content.
path.text = "Some content"
assert path // Now path exists.
