About Question enthuware.jwpv6.2.732 :

[Sireesha]

The options 4 and 5 seems to be the same. But answer picks 4 but not 5 why?

[admin]

No, they are different. 4 is right. The reason is explained in the explanation.

Option 1:
<%@ page import="java.util.*" autoFlush="true"%>
<%@ page import="java.io.*" autoFlush="false"%>
Explanation: Any page directive except import can only occur only once.

So Option 1 should be correct based on the explanation, right?

[admin]

autoFlush is occurs twice in this option.

[shareef.hiasat]

autoFlush is occurs twice in this option.

so if autoFlush occurs twice means its not valid and will not compile ?!

[admin]

Yes, you cannot repeat this attribute.

[kunalh]

Can anyone please explain why option 5 is wrong? I am not able to get a clear understanding from the explanation given in the Test Studio

Thanks

[admin]

There is ! sign in Option 5 and so it is a declaration and will be converted to something like:

Code: Select all

public class test$jsp extends HttpServlet
{
  Hashtable ht = new Hashtable();
  
  ht.put("max", "10"); //1  This line is not ok.
  ....
  public void _jspService(...){ ... }
}
[code]

As you can see Line marked //1 is not valid java code.

HTH,
Paul.

Any page directive except import can only occur only once.

Import may occur multiple times, the problem is with flush attribute.
Please confirm, explanation is not quite correct.

[admin]

Why do you think the explanation is incorrect? It says that same thing you are saying i.e. import can occur multiple times.

[johnlong]

I does not say that the problem is with flush attribute being contradictory in two imports, i.e. multiple imports are fine, unless we don't specify different flush attributes.

[admin]

The code in the option uses autoFlush twice. And the explanation clearly says, "Any page directive except import can only occur only once."
So I am not really sure what are you confused about.

[johnlong]

Actually import can appear multiple times, but without contradictory flush attribute.
