Examples of java.nio.file.Path.normalize()

java.nio.file.Path.normalize()
Returns a path that is this path with redundant name elements eliminated.
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 " {@code .}" and " {@code ..}" are special names used to indicate the current directory and parent directory. In such file systems all occurrences of " {@code .}" are considered redundant. If a " {@code ..}" is preceded by a non-" {@code ..}" name then both names are considered redundant (the process to identify such names is repeated until it is no longer applicable).
This method does not access the file system; the path may not locate a file that exists. Eliminating " {@code ..}" and a preceding name from a path may result in the path that locates a different file than the original path. This can arise when the preceding name is a symbolic link. @return the resulting path or this path if it does not containredundant name elements; an empty path is returned if this path does have a root component and all name elements are redundant @see #getParent @see #toRealPath

    Path file = Paths.get(location);
    if (!file.isAbsolute())
      file = file.toAbsolutePath();
    if (Files.isReadable(file)) {
      try {
        url = file.normalize().toUri().toURL();
      } catch (MalformedURLException e) {
      }
    }
    return url;
