It will print true if p refers to an empty directory.
What if p cannot be accessed/deleted due to missing permissions?

Already mentioned in the comments under option 4: "It will not throw any exception in that case. It will just return false."

what, if p is empty, but we don't have file permission. are we supposed to consider that we have permissions, while choosing for
"It will print true if p refers to an empty directory."
we can never be sure, even if the directory is empty. is my understanding.

Yes, you can assume that permission is there. If the question is about permission, the question will tell you about it.

I tested option 1-2-3. It works as you mentioned but when I lock the file on Mac and then try to delete I get exception like this.
Code: Select all
java.nio.file.FileSystemException: /Users/hasancelik/IdeaProjects/gradle/deleted/text.txt: Operation not permitted
at java.base/sun.nio.fs.UnixException.translateToIOException(UnixException.java:100)

at java.base/java.nio.file.Files.deleteIfExists(Files.java:1181)
at oracle_exam7.question21.Test.main(Test.java:17)
But in the option 4, you mention that we would get just "false". Did I misunderstand something?

You are right. As the JavaDoc for this method says, it returns false if the file could not be deleted because it did not exist.
In other cases, it should throw an IOException or SecurityException.
Fixed.
thank you for your feedback!
