Java file system path




















Parameters: other - the given path Returns: true if this path starts with the given path; otherwise false startsWith boolean startsWith String other Tests if this path starts with a Path , constructed by converting the given path string, in exactly the manner specified by the startsWith Path method.

It does not start with " f " or " fo ". Parameters: other - the given path string Returns: true if this path starts with the given path; otherwise false Throws: InvalidPathException - If the path string cannot be converted to a Path. If the given path has N elements, and no root component, and this path has N or more elements, then this path ends with the given path if the last N elements of each path, starting at the element farthest from the root, are equal.

If the given path has a root component then this path ends with the given path if the root component of this path ends with the root component of the given path, and the corresponding elements of both paths are equal. Whether or not the root component of this path ends with the root component of the given path is file system specific. If this path does not have a root component and the given path has a root component then this path does not end with the given path.

Parameters: other - the given path Returns: true if this path ends with the given path; otherwise false endsWith boolean endsWith String other Tests if this path ends with a Path , constructed by converting the given path string, in exactly the manner specified by the endsWith Path method.

The precise definition of this method is implementation dependent but in general it derives from this path, a path that does not contain redundant name elements. In many file systems, the ". In such file systems all occurrences of ". This method does not access the file system; the path may not locate a file that exists.

Eliminating ".. This can arise when the preceding name is a symbolic link. Returns: the resulting path or this path if it does not contain redundant name elements; an empty path is returned if this path does have a root component and all name elements are redundant See Also: getParent , toRealPath java. If the other parameter is an absolute path then this method trivially returns other. If other is an empty path then this method trivially returns this path. Otherwise this method considers this path to be a directory and resolves the given path against this path.

In the simplest case, the given path does not have a root component, in which case this method joins the given path to this path and returns a resulting path that ends with the given path. Where the given path has a root component then resolution is highly implementation dependent and therefore unspecified. Parameters: other - the path to resolve against this path Returns: the resulting path See Also: relativize java.

Path resolve Path resolve String other Converts a given path string to a Path and resolves it against this Path in exactly the manner specified by the resolve method. Parameters: other - the path string to resolve against this path Returns: the resulting path Throws: InvalidPathException - if the path string cannot be converted to a Path. See Also: FileSystem. String, java. This is useful where a file name needs to be replaced with another file name.

If this path does not have a parent path, or other is absolute , then this method returns other. If other is an empty path then this method returns this path's parent, or where this path doesn't have a parent, the empty path. Parameters: other - the path to resolve against this path's parent Returns: the resulting path See Also: resolve Path resolveSibling Path resolveSibling String other Converts a given path string to a Path and resolves it against this path's parent path in exactly the manner specified by the resolveSibling method.

Parameters: other - the path string to resolve against this path's parent Returns: the resulting path Throws: InvalidPathException - if the path string cannot be converted to a Path. Relativization is the inverse of resolution. This method attempts to construct a relative path that when resolved against this path, yields a path that locates the same file as the given path.

Where this path and the given path do not have a root component, then a relative path can be constructed. A relative path cannot be constructed if only one of the paths have a root component.

Where both paths have a root component then it is implementation dependent if a relative path can be constructed. If this path and the given path are equal then an empty path is returned. For any two normalized paths p and q , where q does not have a root component, p. Parameters: other - the path to relativize against this path Returns: the resulting relative path, or an empty path if both paths are equal Throws: IllegalArgumentException - if other is not a Path that can be relativized against this path toUri URI toUri Returns a URI to represent this path.

The exact form of the scheme specific part is highly provider dependent. In the case of the default provider, the URI is hierarchical with a path component that is absolute. The query and fragment components are undefined. Whether the authority component is defined or not is implementation dependent. There is no guarantee that the URI may be used to construct a java. In the case of the default provider, and the file exists, and it can be determined that the file is a directory, then the resulting URI will end with a slash.

The default provider provides a similar round-trip guarantee to the File class. For a given Path p it is guaranteed that Paths. Whether other providers make any guarantees is provider specific and therefore unspecified. When a file system is constructed to access the contents of a file as a file system then it is highly implementation specific if the returned URI represents the given path in the file system or it represents a compound URI that encodes the URI of the enclosing file system.

A format for compound URIs is not defined in this release; such a scheme may be added in a future release. If this path is already absolute then this method simply returns this path.

Otherwise, this method resolves the path in an implementation dependent manner, typically by resolving the path against a file system default directory. The precise definition of this method is implementation dependent but in general it derives from this path, an absolute path that locates the same file as this path, but with name elements that represent the actual name of the directories and the file.

For example, where filename comparisons on a file system are case insensitive then the name elements represent the names in their actual case. Additionally, the resulting path has redundant name elements removed. If this path is relative then its absolute path is first obtained, as if by invoking the toAbsolutePath method. The options array may be used to indicate how symbolic links are handled. By default, symbolic links are resolved to their final target.

Some implementations allow special names such as ".. When deriving the real path , and a ".. When not resolving symbolic links and the preceding name is a symbolic link then the names are only removed if it guaranteed that the resulting path will locate the same file as this path.

Where this Path is associated with the default provider, then this method is equivalent to returning a File object constructed with the String representation of this path. If this path was created by invoking the File toPath method then there is no guarantee that the File object returned by this method is equal to the original File. Save Article. Like Article.

According to this article resolving symbolic links which always is system dependent does only happen when calling getCanonicalPath, but a simple test case shows that getAbsolutePath also resolves symbolic links.
