java - How do I get a file's directory using the File object?

Consider the code:

File file = new File("c:\temp\java\testfile");

testfile is a file, and it may or may not exist. I want to get the directory c:\temp\java\ using the File object. How do I go about doing this?

In either case, I'd expect file.getParent() (or file.getParentFile()) to give you what you want.

Additionally, if you want to find out whether the original File does exist and is a directory, then exists() and isDirectory() are what you're after.
