JSP Methods

Question:
Is there a way to declare and invoke methods in JavaServer Pages?

Answer:
Methods can be declared in the same way as variables in JavaServerPages. It can help to think of JSP as a convenient syntax fordefining servlets. Any variables or methods that you declare aremembers of the servlet.

The syntax for making declarations in JSPis:

<%! declaration %>

You can access the declared variables and methods in any expression orscriptlet block. The following example demonstrates how to declare amethod and invoke it in a JSP expression.

<%!         public String aMethod() {                return "A String.";         }%>

This JSP page demonstrates how to declare and invoke a method.The next line is the output of calling aMethod():

<%= aMethod() %>
