Get java.nio.file.Path object from java.io.File

Is it possible to get a Path object from a java.io.File?

I know you can convert a path to a file using toFile() method, but I couldn't find the opposite conversion. Is there a way to do this in Java 6 or lower?

Haev you looked at the API documentation? - Vivin Paliath
Yes, I saw the resolve and resolveSibling methods, but that didn't exactly convert from file (or string) to path, but rather concated it in a way. - Karlovsky120
Here is the documentation @VivinPaliath is alluding too. - Perception
It amazes me how the stupidest question possible (I mean, come on, it was in the documentation, short google search would have answered it) is netting me the most points on the site. :D - Karlovsky120
@Karlovsky120 it shouldn't amaze you if you would try to google it yourself ;) - 9ilsdx 9rvj 0lo

Yes, you can get it from the File object by using File.toPath(). Keep in mind that this is only for Java 7+. Java versions 6 and below do not have it.

From the documentation:

Paths associated with the default provider are generally interoperable with the java.io.File class. Paths created by other providers are unlikely to be interoperable with the abstract path names represented by java.io.File. The toPath method may be used to obtain a Path from the abstract path name represented by a java.io.File object. The resulting Path can be used to operate on the same file as the java.io.File object. In addition, the toFile method is useful to construct a File from the String representation of a Path.

(emphasis mine)

So, for toFile:

Returns a File object representing this path.

And toPath:

Returns a java.nio.file.Path object constructed from the this abstract path.

You likely want File.toPath().

As many have suggested, JRE v1.7 and above has File.toPath();

File yourFile = ...;
Path yourPath = yourFile.toPath();

On Oracle's jdk 1.7 documentation which is also mentioned in other posts above, the following equivalent code is described in the description for toPath() method, which may work for JRE v1.6;

File yourFile = ...;
Path yourPath = FileSystems.getDefault().getPath(yourFile.getPath());
