Modifier and Type | Method and Description |
---|---|
static Path |
get(String first,
String... more)
Converts a path string, or a sequence of strings that when joined form
a path string, to a
Path . |
static Path |
get(URI uri)
Converts the given URI to a
Path object. |
public static Path get(String first, String... more)
Path
. If more
does not specify any
elements then the value of the first
parameter is the path string
to convert. If more
specifies one or more elements then each
non-empty string, including first
, is considered to be a sequence
of name elements (see Path
) and is joined to form a path string.
The details as to how the Strings are joined is provider specific but
typically they will be joined using the name-separator
as the separator. For example, if the name separator is
"/
" and getPath("/foo","bar","gus")
is invoked, then the
path string "/foo/bar/gus"
is converted to a Path
.
A Path
representing an empty path is returned if first
is the empty string and more
does not contain any non-empty
strings.
The Path
is obtained by invoking the getPath
method of the default
FileSystem
.
Note that while this method is very convenient, using it will imply
an assumed reference to the default FileSystem
and limit the
utility of the calling code. Hence it should not be used in library code
intended for flexible reuse. A more flexible alternative is to use an
existing Path
instance as an anchor, such as:
Path dir = ... Path path = dir.resolve("file");

public static Path get(URI uri)
Path
object.
This method iterates over the installed
providers to locate the provider that is identified by the
URI scheme
of the given URI. URI schemes are
compared without regard to case. If the provider is found then its getPath
method is invoked to convert the
URI.
In the case of the default provider, identified by the URI scheme
"file", the given URI has a non-empty path component, and undefined query
and fragment components. Whether the authority component may be present
is platform specific. The returned Path
is associated with the
default
file system.
The default provider provides a similar round-trip guarantee
to the File
class. For a given Path
p it
is guaranteed that
Paths.get(p.so long as the originaltoUri
()).equals( p.toAbsolutePath
())
Path
, the URI
, and the new Path
are all created in (possibly different invocations of) the same
Java virtual machine. Whether other providers make any guarantees is
provider specific and therefore unspecified.uri

- if preconditions on the uri
parameter do not hold. The

- The file system, identified by the URI, does not exist and
cannot be created automatically, or the provider identified by
the URI's scheme component is not installedSecurityException
