The difference between the GetFile () and the GetPath () method of the URL (goto)

Go from blog: http://blog.csdn.net/l375852247/article/details/7999063

Importjava.net.MalformedURLException; ImportJava.net.URL;  Public classDD {/**      * @paramargs*/       Public Static voidMain (string[] args) {Try{URL URL=NewURL ("file://ftp.yoyodyne.com/pub/files/foobar.txt?id=123456"); System.out.println ("Url.getfile () =" +url.getfile ()); System.out.println ("Url.getpath () =" +Url.getpath ()); } Catch(malformedurlexception e) {e.printstacktrace (); }      }  }  

Results returned:

Url.getfile () =/pub/files/foobar.txt?id=123456
Url.getpath () =/pub/files/foobar.txt

When the above

Change into

File://ftp.yoyodyne.com/pub/files/foobar.txt  

When

Results returned:

Url.getfile () =/pub/files/foobar.txt
Url.getpath () =/pub/files/foobar.txt

The Java docs document says:

The URL.getFile() Javadocs say this:

Gets the file name of this URL. The returned file portion would be the same as GetPath (), plus the concatenation of the value of Getquery (), if any. If There is no query portion, the This method and GetPath () would return identical results.

They'll be the same unless there are a query string, e.g. a in the ?somename=value&somethingelse=value2 URL.

I was a novice before I had not known what was going on, now understand!
