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() %>
