Method in Declaration Tag
In Jsp we define methods just like as declare them in
standalone applications. In jsp we have been provided a such a tag where we can
declare methods and variables. Anything which will be declared inside this tag
will be applicable within the whole application. We call this tag a Declaration
Tag. The syntax of this tag is <%! --------- %>.
In this simple jsp program we are declaring two methods
getName() of type String and the second one named as getAge() which is of int
type. These two methods are declared inside the declaration tag so, that these
methods can be accessed from anywhere in the class. The values of these methods
are accessed by using the out implicit object, which is responsible for writing
the content to the browser.
The code of the program is given below:
<%!
private String getName()
{
return "Ujjawal";
}
private int getAge()
{
return 5;
}
%>
<HTML>
<HEAD><TITLE>Declaration Tag in jsp - Methods</TITLE></HEAD>
<%
out.println ("Name: "+getName()+"<br>");
out.println ("Age: "+getAge()+" months");
%>
</HTML>
