Question

Which of the following JSP expressions are valid?

Choices

Choice (4) Response

a.

< %= “Sorry” + “for the” + “break”; % >

b.

< %= “Sorry” % >

c.

< %= “Sorry” + “for the” + “break” % >

d.

Both c. and b. are correct

Answer

d.

Explanation

  • Code placed within JSP expression tag is written to the output stream of the response.

  • So there is no need to write out. print () to write data.

  • The value of an expression inside JSP expression is converted to a String.

  • We can use an expression within a line of text, whether or not it is tagged with HTML, in a JSP file.

  • The expression element can contain any expression that is valid according to the Java Language Specification but we cannot use a semicolon to end an expression.

Syntax of JSP extension:

< %= Expression % >

Example:

  1. <html>
  2. <body>
  3. <%=”welcome to jsp” %>
  4. </body>
  5. </html>
  • So, the correct answer is < %= “Sorry” + “for the” + “break” % > and < %= “Sorry” % > .
