Dear all,
I appeared for SCJP 2 in Decemeber 1999. I got 69% and did not manage to clear it. I referred to RHE that time. I planned to reappear for it once more but could not materialise. Now I am planning to take the exam this month-end. Can anyone
Ajith,Maha and everyone tell me if there is any change in the exam pattern than that followed by RHE book. I relied heavily on it. But last time it was due to my silly mistakes that I didnt clear. But RHE was sufficing the objectives very much and the ques. were of the similar standard as given at back of RHE.
Is RHE still the same good reliable book or the things have change in past 7 months. Please advise because it still remains the core of my preparation strength.

hey,

To all javaranch moderators (Tony, maha anna, ajith, paul) thank you very much for sharing your knowledge. Same to all those followers of these wonderful site.
I hardly pass the exam with a score of 75%. I must admit that I am a bit disappointed with my score. I�m thinking of retaking the exam in hope of improving my score. Is it worth to take another exam? Can someone advised me with this one?
To tell you the truth, I�m a bit uncomfortable with my basic knowledge in java. During the last week of my preparation, I even prefer to play Tekken , instead of clarifying my fundas. It really didn�t help at all. I decided to take the exam because all I wanted is to get over with this preparation. I still have this attitude of waiting for the last day to prepare like I did during my college years. I think this is the first thing I should try to improve before I take another step towards achieving another goal.
My advise to all candidates for SCJP, be confident with your java fundamentals. Always make it a point to visit this site coz you may find topics here that will really clarify your understanding in java. Try to write programs to clarify things playing inside your mind.
Catch you later!


In Java 2,
goto, const - reserved keywords
true, false - not keywords( they are boolean literals)
null - not keywords( it is reference value)
strictfp - reserved keywords introduced in Java2.

I discovered these new keywords on the Marcus Green site.As to my knowlege 'goto' and 'const' are no more keywords of java, although they were earlier.Please guide from exam perspective for java platform 2 certification.


Hi,
regarding this syllabus and pattern change for SCJP2 exam, I have enquired by contacting sun. They replied me, they are going for annual update. But not sure from when they will implement it. Also they said, if they are going for a change definitely they will put in their web page. So i think till they announce we no need to worry about this change.
you can conform this by mailing to

As to your question , I also plan to take in the exam with in the next few day. As to my knowledge the new beta test exam will commence on august 8, the registration for the exam is already closed.Taking the exam in the month of August should not seem to be a problem for you considering the time for feedback and launch of the new platform 2 objectives.I would estimate a minimum of 15 days to a month's time for the refurbishment of the new syllabus to launch after the beta test trial.Also the beta test is a trial test to recieve appropriate feedback from the appearing candidates by Sun Microsystems.
Hope this encourages you for the exam.

hi,
what I've posted is not clear. You refer this again.
here is the explanation for your question.
In your program
float f = 1.0f,zf;
double d=1.0,zd;
int i=0;(in for loop i vary from 0 to 99)
For the expression zf = (f/i)*i You've got the answer as
inexact results with float: 0 41 47 55 61 82 83 94 97
here i gets promotes to float
For the expression zd = (d/i)*i You've got the answer as
inexact results with double: 0 49 98[/B]
here i gets promotes to double
As we know since float are 32 bits and double are 64 bits.
consider the case i = 41; do the calculation for both experssion
(pl check both zf and zd for different values of i)

zf = 1.0f/i*i
zd = 1.0/i*i
for i = 0, zf = 0, zd = 0;
for i = 41, zf = 0.99999999, zd = 1.0
for i = 47, zf = 0.99999994, zd = 1.0
for i = 49, zf = 0.1, zd = 0.999999999999999
like this you can check for all values of 0<100.

The reason is:
In case of zf i gets promotes to float so the calculation is done for 32 bits.
In case of zd i gets promotes to double so the calculation is done for 64 bits.

I hope this is the answer.

0 0.0 0.0 0 0
41 0.99999999 1.0 41 -
47 0.99999994 1.0 47 -
49 1.0 0.9999999999999999 49 49
. . . . .
. . . . .
. . . . .
97 not 1 97
98 not 1 98
99 . . . .

The reason is:
In case of zf i gets promotes to float so the calculation is done for 32 bits.
In case of zd i gets promotes to double so the calculation is done for 64 bits.

I hope this is the answer.

Hi All,
In Java null, true, false are keywords or not?
According to Jaworski Mock up exam, above three are not keywords. He has given that valus are not keywords.
But according to Sun's CoreJava book, I found null is a keyword.
Any one can clear my doubt.
thanks in advance.
Also I want to tell one more thing.
In Jaworski Mockup exam one question's answers is wrong. i.e he has given that example of polymorphism is overloading. But as I know the correct answer is overriring.

Hi Aruna,
As I know, top level classes may not be private,protected. transient is applicable only for variables.
native is applicable only for functions ( to call a fn. of like c/c++).
So none of the answers are correct.

1. protected class Frog extends Animal
2. private class Frog extends Animal
3. transient class Frog extends Animal
4. native class Frog extends Animal
Thx
