Expressions

• A JSP expression is very similar to a scriplet, except that the enclosing Java code is required to be an expression.

• The expression is evaluated, then converted to a String.

• The string is effectively interpolated into the template text—wherever the element appears—and sent to the browser as part of the generated HTML.

• The syntax of a expression element is:

  <%= Java expression in here %>
  
  • Distinguished from a scriptlet by the = sign attached to <% .
