The fn:join() function concatenates all the elements of an array into a string with a specified separator.
The fn:join() function has following syntax:
String join (java.lang.String[], java.lang.String) |
Following is the example to explain the functionality of this function:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %> <html> <head> <title>Using JSTL Functions</title> </head> <body> <c:set var="string1" value="This is first String."/> <c:set var="string2" value="${fn:split(string1, ' ')}" /> <c:set var="string3" value="${fn:join(string2, '-')}" /> <p>Final String : ${string3}</p> </body> </html> |
Note: fn:split() function returns an array splitting into diffrenet elements.
This would produce following result:
Final String : This-is-first-String. |
