Splitting a URL-formatted String using Java

Question

I have a String which is a website URL, such as "http://www.abcd.com/en/sites/default/files/pic.jpg". I want to split this String so that I can change some of the path values, such as changing /files/ to /newfolder/.

Is this easily achievable?

String[] afterSplit = yourString.split("files/");
String newString = afterSplit[0];
newString += "/newfolder/";
newString += afterSplit[1];

With a standard String.split() method, since you asked for splitting. newString is the resulting string.

This will remove the part after the last "/" and append "newfolder/pic.jpg"

String str = "http://www.abcd.com/en/sites/default/files/pic.jpg";
str.substring(0, s.lastIndexOf("/") + 1) + "newfolder/pic.jpg";

In my opinion this is the best (most flexible) possibility (or even more general str.substring(0, s.lastIndexOf("/") + 1) + "newfolder" + substring(s.lastIndexOf("/"));)

Use a replace function and replace "files/" by "files/newfolder/", for example.

Yh..i get it..Thanks for your help :)

The solution with replace fails if the path before 'files' also contains 'files', for example in http://www.abcd.com/en/sites/files/default/files/pic.jpg

Good objection, but maybe not relevant in his setup.

How about:

String parts[] = String.split(oldPath, "files\");
String newPath = parts[0] + "newfolder\" + parts[1];

I haven't tested it but in theory it should work. There could be a problem with the backslash in the regular expression, but if so, its easy to fix.

Regards,

This works:

String input = "http://www.abcd.com/en/sites/default/files/pic.jpg";
int lastIndexOfSlash = input.lastIndexOf('/');
String result = input.substring(0, lastIndexOfSlash + 1) + "newfolder/" + input.substring(lastIndexOfSlash + 1);

this should work:

String s = "http://www.abcd.com/en/sites/default/files/pic.jpg";
StringBuilder sb = new StringBuilder(s);
sb.insert(sb.lastIndexOf("/"), "/newfolder");
s = sb.toString();
