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.
