When ``++java.io.File#delete++`` fails, this ``++boolean++`` method simply returns ``++false++`` with no indication of the cause. On the other hand, when ``++java.nio.file.Files#delete++`` fails, this ``++void++`` method returns one of a series of exception types to better indicate the cause of the failure. And since more information is generally better in a debugging situation, ``++java.nio.file.Files#delete++`` is the preferred option.


== Noncompliant Code Example

----
public void cleanUp(Path path) {
  File file = new File(path);
  if (!file.delete()) {  // Noncompliant
    //...
  }
}

== Compliant Solution

----
public void cleanUp(Path path) throws NoSuchFileException, DirectoryNotEmptyException, IOException {
  Files.delete(path);
}
