I was preparing for the SCWCD Exam and then because of some circumstances I had to move out of town. All of a sudden I decided to take this exam before I moved and hence dared to take the exam with even taking any practise exams.
I was not sure if I was going to clear this as I did not feel as prepared as I was for SCJP. For SCJP I had reviewed the postings on this site and had taken plenty of mock tests. On the contrary, I had not reviewed many postings on the SCWCD Forum of this site and neither had taken any practise tests because of the time constraint.But yet I cleared the exam with a decent 83%. The SCWCD Study Kit by Deshmukh is undoubtedly the best book for this exam. Also the Exam review notes given at the end of this book proved very helpful to me.
All I want to say is :
  • The SCWCD Study Kit Book (by Deshmukh and Mavalia) is pretty much all you need to be prepared with for this exam
  • And do review the Exam notes given at the end of this book. ( Do not say you did not have time for this because this would not take too long and this is very valuable to be ignored)

  • Lastly, I would like to thank all you Java Ranchers, Bartenders and the rest of the ELITE members of this community for all the moral and the intellectual support .

    The Rules given on page # 74 of the SCWCD Study Kit (by Deshmukh) explains this point. Further explaination of the same point can be found on the page # 75 too.

    Hi varun,
    You said you had 2 years experiance in Java. Was this on Core Java or JSPs and Servlets ? I was wondering if one needs to have a lot of real time experiance to take up this exam.

    Hi Ben,
    COngrats !! Any suggestions on the best way to prepare for the SCWCD Exam ? Does one need a lot of real time experiance to score well on this exam ? Did you have any experiance with JSPs and Servlets before you started preparing for the exam ?

    I passed my SCJP 1.4 Exam with 85%. I think I could have done better but was quite tensed Nevertheless, I am happy with the score. I was asked a lot of questions on Threads and Assertions.
    I thank all those members of this great site wo helped me with my doubts and/or helped with with thier own doubts. I refered mostly to the book by Kathy and Bert and should say that the book was my saviour . Also the mock exams collection on Maha Anna's page was very useful and I wish Maha considered updating this page.
    I wish to take up the SCWCD exam in the near future but am not sure if I should go for it now or later as I remember Kathy('The CowGirl') mentioning that the SCWCD exam pattern might change very soon.
    Any suggestion on if I should take the SCWCD exam now(i.e in the next two months) or should I wait untill the exam in changed ? Also what would be the best way to prepare for the SCWCD ? To start with ,I have bought the Manning Book what else do I do ?
    Also, does everyone here feel that one would need a lot of real time experiance on JSPs and Servlets to take up this exam ? I need to think about this because I am a student.
    Once again . Thanks to everyone who helped me
    I will continue to hang around and will continue on my journey of certifications.

    Roger and Preeti,
    That was some good explaination !! I sure agree to it and add that I have personally tried all this by writing some code. And now going back to Ross's question,

    However, in the two-minute drill on page 133, they state that "Interfaces are by default public and abstract - explicit declaration of these modifiers is optional."

    Are we to now conclude that the above sentence is an error in this book ? Ofcourse this could not be an error if Kathy and Bert were actually refering to the members instances within an Interface.

    It sure does. I feel so bad that it did not strike me. As I said I knew it was easy but ..
    Thanks for your reply.
    Thank You Monisha. I am sure this discussion will prove helpful to a lot of us who are yet to take this exam in the near future.
    I have a question. I know it is simple but somehow it just does not strike to me. I guess I am too stressed out
    I have an abstract class that has two methods - one declared abstract [i.e Method1()] and the other that is defined [Method2()]. In my Concrete Class, I have defined Method1() and want to override Method2().I wish to override Method2() as I would like to extend the functionality of this method which was already defined.
    My question is: While overriding the Method2() how do I call the Method2() of the Abstract Class?

    The code for the above scenario Could be like this :
    The code for the Abstract Class :

    The code for the Concrete Class :

    As rightly pointed at already, the Compile errors are thrown from lines 4 and 6.
    The line 7 does not give a compile time error because the trim() method does ofcourse return a new String object but in the above given code this new String object is not assigned to any other String reference.
    Hence the code is syntactically correct but nevertheless the line 7 is of no use unless the String object returned from the trim() method is stored.
    Hi Everybody,
    Thanks a lot for explaining this. All the above explainations were great.
    For whatever reason, it never struck me that toString() method was returning a new String Object. I sure will try to remember that :-)
    Hi Anupam,
    You could say that but there is a clause that you should add to your statement and that is .. Your statement is true only for Method local Variables. But if the final variable was an instance variable and if that was not initialised in the declaration statement, the code would not compile.
    And the Answer to your second question, regarding the difference between the Final and non-final variables is primarly that the value of the final varible cannot be changed once its intialized, while you can re-assign values to non-final variables any number of times.
