Free SCWCD Certification Practice Questions:

What will be the output of the following JSP code?

<html><body>
<% int a = 10; %>
<%! int a = 20; %>
<%! int b = 30; %>
The value of b multiplied by a is <%= b * a %>
</body> </html>

  • A) The code will not compile
  • B) The value of b multiplied by a is 30
  • C) The value of b multiplied by a is 300
  • D) The value of b multiplied by a is 600
  • E) The value of b multiplied by a is 0

    • [Ans: C]

    • Although the variable "a" is declared twice, the code should still compile as written. In the first declaration <% int a = 10; %>, the variable "a" will be declared as a local variable. In the second declaration <%! int a = 20; %>, the variable "a" will be declared as an instance variable, global to the translated servlet class.

      Upon translation, the JSP engine will translate the code similar to the following:


      public class ..._jsp
      {
      int a = 20;
      int b = 30;
      public void _jspService (....)
      {
      int a = 10;
      out.write ("The value of b multiplied by a is ");
      out.print (b * a);
      }

      Since the local variable "a" has precedence over the global variable "a", the expression (b * a) evaluates as (30 *10), which equals 300.
