Expression Tag in JSP:
Expression tag is used to display output of any data on the generated page. The data placed in Expression tag prints on the output stream and automatically converts data into string.

Expression tag must begin with <%= Inside Expression tag, the user embeds any Java expression. Expression tag ends with the notation %>.
NOTE: Expression should not contain a semicolon between codes, as with Declaration tag.
General syntax of Expression Tag:
<%! //start of declaration tag

%> //end of declaration tag
