To manipulate the string that ends with a specific characters or string in JSP, JSTL provides a function endsWith(). This function helps in to work with the suffix associated with a string.
Syntax:
The fn:endsWith() function has following syntax:
boolean endsWith(java.lang.String, java.lang.String)
JSTL fn endsWith Example-

<title>JSTL EndsWith Function Example</title>
</head>
<body>
<c:set var="array1" value="${fn:endsWith('Hi My name is Dinesh', 'Dinesh')}">
</body>
</html>
Output: true
As you can see above, fn:endsWith() takes two Strings as input parameters.
First parameter in JSTL endsWith function is the target String which needs to be validated.
Second parameter in JSTL endsWith function is the specified string that needs to be matched with starting character sequence of the target string.
If target string ends with same character sequence like the specified string than JSTL endsWith function returns true otherwise returns false.

<body>
<c:set var="theString" value="I am a good programmer in java"/>
<c:if test="${fn:endsWith(theString, 'java')}">
<p>String ends with java<p>
</c:if>
<c:if test="${fn:endsWith(theString, 'CPP')}">
<p>String ends with CPP<p>
</c:if>
</body>
</html>
This would produce following result:
String ends with java
