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. The Expression tag can contain any Java expression
used for printing output equivalent to out.println().Thus, an expression tag
contains a scripting language expression which is evaluated, automatically
converts data to a String and the outputs are displayed.
Notation of Expression tag is shown below:
<%= %>
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.
