First parameter in JSTL Substring function is the target String from which you want to derive the substring.
Second parameter in JSTL Substring function is the start index. Character at this index is included in the substring.
Third parameter in JSTL Substring function is the end index. Character at this index is excluded from the substring. Substring will end at the previous index.
The fn:substring() function returns a subset of a string specified by start and end indices.
Syntax:
The fn:substring () function has following syntax:
java.lang.String substring(java.lang.String, int, int)
Example:
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:substring(string1, 5, 15)}" /> <p>Final sub string : ${string2}</p> </body> </html>
This would produce following result:
Final sub string : is first S
