What is JSP Expression

by

A scripting element that contains a valid scripting language expression that is evaluated, converted to a String, and placed into the implicit out object.

In Advanced Java, a JSP expression is a piece of code embedded in a JavaServer Pages (JSP) file that is evaluated, converted to a string, and inserted in the place where the expression appears in the JSP file. JSP expressions are enclosed within <%= and %> tags.

For example:

jsp
<p>Today's date is <%= new java.util.Date() %></p>

In this example, <%= new java.util.Date() %> is a JSP expression that will be replaced with the current date when the JSP page is executed on the server.

JSP expressions are commonly used to embed dynamic data or Java code within HTML pages, making it easier to create dynamic web applications.
