JSP | ScriptletTag

The Scriptlet Tag in JSP is used to embed Java code directly into a JSP page. The code written inside the <% %> tag is executed on the server whenever a request is made, helping generate dynamic content. It is one of the basic scripting elements provided by JSP.

• Allows writing control statements like loops and conditions (if, for, while)
• Can access request parameters and session data
• Used for processing logic, not just displaying output

Syntax:

<%

// Java code here

%>

Example:

Output:

Value of num is: 10
