URL(String spec)
          Creates a URL object from the String representation.
URL(String protocol, String host, int port, String file)
          Creates a URL object from the specified protocol, host, port number, and file.
URL(String protocol, String host, int port, String file, URLStreamHandler handler)
          Creates a URL object from the specified protocol, host, port number, file, and handler.
URL(String protocol, String host, String file)
          Creates a URL from the specified protocol name, host name, and file name.
URL(URL context, String spec)
          Creates a URL by parsing the given spec within a specified context.
URL(URL context, String spec, URLStreamHandler handler)
          Creates a URL by parsing the given spec with the specified handler within a specified context.


That is the API of the URL constructors, use the first one if you don't know how other ones work
I think that should be sufficient:
URL(String spec)
