Examples of java.net.URI.normalize()

java.net.URI.normalize()
etf.org/rfc/rfc2396.txt">RFC 2396, section 5.2, step 6, sub-steps c through f; that is:
1. All "." segments are removed.
2. If a ".." segment is preceded by a non-".." segment then both of these segments are removed. This step is repeated until it is no longer applicable.
3. If the path is relative, and if its first segment contains a colon character (':'), then a "." segment is prepended. This prevents a relative URI with a path such as "a:b/c/d" from later being re-parsed as an opaque URI with a scheme of "a" and a scheme-specific part of "b/c/d". (Deviation from RFC 2396)
A normalized path will begin with one or more ".." segments if there were insufficient non-".." segments preceding them to allow their removal. A normalized path will begin with a "." segment if one was inserted by step 3 above. Otherwise, a normalized path will not contain any "." or ".." segments.
@return A URI equivalent to this URI,but whose path is in normal form
