Let’s learn delete a directory recursively in java 8.
Delete a directory recursively in java 8
In the below example we are using Files.walk(path) method which returns a Stream that is lazily populated with Path by walking the file tree rooted at a given starting file.
The file tree is traversed depth-first, the elements in the stream are Path objects that are obtained as if by resolving the relative path against start. Now let’s see java program.
import java.io.File; import java.io.IOException; import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; import java.util.Comparator; public class Java8DeleteDirectory { public static void main(String[] args) throws IOException { Path directory = Paths.get("A:/java/directory"); Files.walk(directory) .sorted(Comparator.reverseOrder()) .map(Path::toFile) .forEach(File::delete); } }
