JSP declaration tag

A JSP declaration is used to declare variables and methods in a page’s scripting language.

The syntax for a declaration is as follows:
<%! scripting-language-declaration %>

Example for declaring Variable:
index.jsp
 <html>   
 <body>   
 <%! int a=5; %>   
 <%= "Value of Integer a is "+ (++a) %>   
 </body>   
 </html>   

Example for declaring method : 
index.jsp
 <HTML>  
 <BODY>  
 <%!  
   void getName()  
   {  
     System.out.println( "LoveJavaBytes" );  
   }  
 %>  
 Name is : <%= getName() %>  
 </BODY>  
 </HTML>
