Remarks

An object that may be used to locate a file in a file system. It will typically represent a system dependent file path.

A Path represents a path that is hierarchical and composed of a sequence of directory and file name elements separated by a special separator or delimiter. A <em>root component</em>, that identifies a file system hierarchy, may also be present. The name element that is <em>farthest</em> from the root of the directory hierarchy is the name of a file or directory. The other name elements are directory names. A Path can represent a root, a root and a sequence of names, or simply one or more name elements. A Path is considered to be an empty path if it consists solely of one name element that is empty. Accessing a file using an empty path is equivalent to accessing the default directory of the file system. Path defines the #getFileName() getFileName, #getParent getParent, #getRoot getRoot, and #subpath subpath methods to access the path components or a subsequence of its name elements.

In addition to accessing the components of a path, a Path also defines the #resolve(Path) resolve and #resolveSibling(Path) resolveSibling methods to combine paths. The #relativize relativize method that can be used to construct a relative path between two paths. Paths can be #compareTo compared, and tested against each other using the #startsWith startsWith and #endsWith endsWith methods.

This interface extends Watchable interface so that a directory located by a path can be #register registered with a WatchService and entries in the directory watched.

<b>WARNING:</b> This interface is only intended to be implemented by those developing custom file system implementations. Methods may be added to this interface in future releases.

<h2>Accessing Files</h2>

Paths may be used with the Files class to operate on files, directories, and other types of files. For example, suppose we want a java.io.BufferedReader to read text from a file "access.log". The file is located in a directory "logs" relative to the current working directory and is UTF-8 encoded.

Path path = FileSystems.getDefault().getPath("logs", "access.log");
                BufferedReader reader = Files.newBufferedReader(path, StandardCharsets.UTF_8);

"interop"><h2>Interoperability</h2>

Paths associated with the default java.nio.file.spi.FileSystemProvider provider are generally interoperable with the java.io.File 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 java.io.File#toPath 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 toFile method is useful to construct a File from the String representation of a Path.

<h2>Concurrency</h2>

Implementations of this interface are immutable and safe for use by multiple concurrent threads.

Disposed()	Called when the instance has been disposed. (Inherited from IJavaPeerable)
DisposeUnlessReferenced()	If there are no outstanding references to this instance, then calls `Dispose()`; otherwise, does nothing. (Inherited from IJavaPeerable)
EndsWith(IPath)	Tests if this path ends with the given path.
EndsWith(String)	Tests if this path ends with a `Path`, constructed by converting the given path string, in exactly the manner specified by the `#endsWith(Path) endsWith(Path)` method.
Equals(Object)	Tests this path for equality with the given object.
Finalized()	Called when the instance has been finalized. (Inherited from IJavaPeerable)
ForEach(IConsumer)	Performs the given action for each element of the `Iterable` until all elements have been processed or the action throws an exception. (Inherited from IIterable)
GetHashCode()	Computes a hash code for this path.
GetName(Int32)	Returns a name element of this path as a `Path` object.
Iterator()	Returns an iterator over the name elements of this path.
Normalize()	Returns a path that is this path with redundant name elements eliminated.
Of(String, String[])
Of(URI)	Returns a `Path` by converting a URI.
Register(IWatchService, IWatchEventKind[], IWatchEventModifier[])	Registers the file located by this path with a watch service.
Register(IWatchService, IWatchEventKind[])	Registers the file located by this path with a watch service.
Relativize(IPath)	Constructs a relative path between this path and a given path.
Resolve(IPath)	Resolve the given path against this path.
Resolve(String)	Converts a given path string to a `Path` and resolves it against this `Path` in exactly the manner specified by the `#resolve(Path) resolve` method.
ResolveSibling(IPath)	Resolves the given path against this path's `#getParent parent` path.
ResolveSibling(String)	Converts a given path string to a `Path` and resolves it against this path's `#getParent parent` path in exactly the manner specified by the `#resolveSibling(Path) resolveSibling` method.
SetJniIdentityHashCode(Int32)	Set the value returned by `JniIdentityHashCode`. (Inherited from IJavaPeerable)
SetJniManagedPeerState(JniManagedPeerStates)	(Inherited from IJavaPeerable)
SetPeerReference(JniObjectReference)	Set the value returned by `PeerReference`. (Inherited from IJavaPeerable)
Spliterator()	Creates a `Spliterator` over the elements described by this `Iterable`. (Inherited from IIterable)
StartsWith(IPath)	Tests if this path starts with the given path.
StartsWith(String)	Tests if this path starts with a `Path`, constructed by converting the given path string, in exactly the manner specified by the `#startsWith(Path) startsWith(Path)` method.
Subpath(Int32, Int32)	Returns a relative `Path` that is a subsequence of the name elements of this path.
ToAbsolutePath()	Returns a `Path` object representing the absolute path of this path.
ToFile()	Returns a `File` object representing this path.
ToRealPath(LinkOption[])	Returns the <em>real</em> path of an existing file.
ToString()	Returns the string representation of this path.
ToUri()	Returns a URI to represent this path.
UnregisterFromRuntime()	Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations. (Inherited from IJavaPeerable)
