How can I split a String in Expression Language and take the last element?

This is what I am trying but it seems not to work:

(myStringHere.split(".")[(myStringHere.split(".").length)-1]).concat(text[myStringHere])

The string I have will be something like this:

com.foo.bar.zar.gar.ThePartIWant

ThePartIWant is what I want to show in the page only.

I am using Expression Language 2.2

If you are doing it in JSP then try with JSP JSTL function tag library that provide lost of methods as defined here in JavaDoc

Read more here on Oacle The Java EE 5 Tutorial - JSTL Functions

Here is the code to get the last value based on split on dot.

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
 ...

<c:set var="string1" value="This.is.first.String." />
<c:set var="string2" value="${fn:split(string1, '.')}" />

<c:set var="lastString" value="${string2[fn:length(string2)-1]}" />

<c:out value="${lastString }"></c:out>

output:

String

Here is one more example

Try this : 

String s = "com.foo.bar.zar.gar.ThePartIWant";

System.out.println(s.split("\\.")[(s.split("\\.").length)-1]);

"." is a special character. You have to escape it because period means any character in regex.

You want to catch only the last part of your string ? Try this : 

string[] s_tab = myStringHere.split(".");
string result = s_tab[s_tab.length - 1];

If you want it in one line :

string result = myStringHere.split(".")[StringUtils.countMatches(myStringHere, ".")];
