Making a song name out of a URL

I have a URL and I want it to look like this:

Action Manat开发者_如何学编程ee - Action

http://xxxxxx.com/songs2/Music%20Promotion/Stream/Action%20Manatee%20-%20Action.mp3

What is the syntax for trimming up to where it after this "Stream/" and make spaces where the %20 is. I also want to trim the .mp3

---

Hmm, for that particular example, I would split the string according to the '/' character then trim the text that follows the final '.' character. Finally, do a replace of "%20" into " ". That should leave you with the string you want

Tested

String initial = "http://xxxxxx.com/songs2/Music%20Promotion/Stream/Action%20Manatee%20-%20Action.mp3";

String[] split = initial.split("/");

String output = split[split.length-1];

int length = output.lastIndexOf('.');
output = output.substring(0, length);
output = output.replace("%20", " ");

String urlParts[] = URL.split("\/");
String urlLast = urlParts[length-1];
String nameDotMp = urlLast.replaceAll("%20");
String name = nameDotMp.substring(0,nameDotMp.length-5);

You could use the split() and replace() methods to accomplish this, here are two ways:

Split your string apart by using the forward slashes:

string yourUrl = [URL Listed];

//Breaks your URL into sections on slashes
string[] sections = yourUrl.split("\/"); 

//Grabs the last section after the slashes, and replaces the %20 with spaces
string newString = sections[sectiongs.length-1].replace("%20"," ");

Split your string at the Stream/ section: (Only use this if you can guarantee it will be in that form)

string yourUrl = [URL Listed];

//This will get everything after Stream (your song name)
string newString = yourUrl.split("Stream\/")[1]; 

//Replaces your %20s with spaces
newString = newString.replace("%20"," ");

URL songURL = new URL("yourpath/filename");
String filename = songURL.getFile();
