HFSJ Chapter 11 mock Q 8 doubt

[Reshma Shanbhag]

Hi,

Which statemets about the <init-param> DD elements are true?

a.) They are used to declare initialization parameters for a specific servlet.

b.) They are used to declare initialization parameters for entire web app.

c.) The method that retrives these parameters returns an object.

d.)The method that retrives these parameters takes a String.

Given answers are A & D

Why is C not considered correct???as it says returns an object and not returns Object, String is object .... cant it be thought of this way .. ??


It would be helpful if one of you could help.

Thanks,
Reshma

c would be right if they'd say :
c.) The method that retrives these parameters returns a String.

You're being picky here

[Harpreet Hira]

java.lang.String getInitParameter(java.lang.String name)

Returns a String containing the value of the named initialization parameter, or null if the parameter does not exist.

Yes i know that getInitParameters(String) returns a String, my intension of asking this question was to know how to analyze the options.

[ludoviko azuaje]

i guess it is a typo error:

it should be:

c.) The method that retrives these parameters returns an Object.

bye.
