JSP scriptlets

JSP scriptlets are blocks of Java code that are embedded directly into a JSP page. Scriptlets are enclosed in <% and %> symbols, and can be used to perform any Java operation, such as database queries, data processing, or logic statements. Here's an example of a scriptlet that generates a dynamic message based on the current time:

bash
Copy code
<html>
<head>
	<title>Example JSP Scriptlet</title>
</head>
<body>
	<%
		String message;
		int hour = new java.util.Date().getHours();
		if (hour < 12) {
			message = "Good morning!";
		} else if (hour < 18) {
			message = "Good afternoon!";
		} else {
			message = "Good evening!";
		}
	%>
	<h1><%= message %></h1>
</body>
</html>

In this example, the scriptlet generates a dynamic message based on the current time, using the java.util.Date class to get the current hour, and then using an if-else statement to set the message based on the hour. The <%= %> syntax is used to output the message as HTML.

Scriptlets are a powerful way to generate dynamic content in JSP pages, but it is important to note that they can make the page harder to read and maintain. To avoid this, it is often recommended to use custom tags or other methods to separate the Java code from the HTML markup.
