I do apologize but, it's only you, who can tell, if you are ready for the exam or not!!
If you've covered all other topics meticulously, you should do fine. Make sure you cover topics on language fundermentals, definig classes, threads, Utility Classes and inheritance before taking the exam.
I think only two or so questions came from I/O.
Please make sure you practice mock exams from now on, till the exam date. It is important you study mock exams, and know why you missed any questions you did on the test.
JQPLUS is very good, in that, you can customise the questions you do in areas where you are weakest. I suggest you do this with JQPLUS and any other mock exams you may have.
All in all, you sound like you are ready, even though you may not be conversant with I/O . Make sue you study THREADS though !!
Best of luck,
Make sure you notify me when you pass the exam!!

Thanks you Karen,
....it took me a good 6 months to prepare for the exam, but you could probably do it in less than 3 months, if you focus !!
Bear in mind that I had a full time job while studying ..yep, a 9-5, 40hrs a day, 5 days a week job!!
I actually did most of my studying on Saturdays and Sundays with help from my room-mate, who is a guru at computer programming.
He still curses me for those nights I would wake him up to ask why my programmes weren't compiling!!
For the first two and a half months, I wrote simple "hello world
like" programes and played around with codes. It can be very frustrating when you compile your java source codes and get thousands of errors, but trust me, once you learn why you're having the errors and then go back to correct them, you'll learn faster than any book or trainning class ever recommended!!
The next one and a half months, I spent reading the following books/online tutorials:
1) Sams Teach Yourself Java 2 Platform in 21 Days,
Professional Reference Edition
2) http://www.jchq.net/tutorial/introj2.shtml
3) Java 2 Exam Cram, Second Edition by Bill Brogden
The last months was used to practice the JQPLUS exam, visit JavaRanch, and write many more complex codes. A list of other websites I studyied at, can be viewed from previous postings at javaranch.
As for the exam, its not as hard, but very tricky. Read the questions very carefully and try to determine what the question is asking for!!
As for me, I am currently studing for my Mircrosoft Certified Professional + Internet. The books I am currently studying are as voluminous as the Encyclopedia Briticana and the context is like Chinese to me, but I do intend to pass it.
I then intend to combine both knowledge from my Java and
MCP + Internet, and work for a good reputable E-Commerce company in the US.
I guess that wraps it all Karen,
I will be praying that you pass the exam too !!

....all the best, I know you'll make it!!
Make sure you post your results at Javaranch after the exam, as
it'll help give other ranchers hope of passing the Java 2 exam.

Thank you,......all this is kind of overwhelming!!
Everyone has been a great help, and I will forever patronize Javaranch for all the help and assistance given to me while preparing for my exams.
I'm looking for E-commerce/Web design entry level jobs, in the US, that will help reinforce the knowledge I have in Java, HTML, CSS and VB Script.
Does anyone have any suggestions?

Thank you once again,

please get a copy of the following, and the exam should be a breeze through !!
1) JQPLUS
2) Bill Brodgen's Exam Cram book
3) Visit JavaRanch everyday for more insights into basic java code programming language and concepts/inquiries posted .
4) go through the following mock exams listed below, if you get average of 75%, then you're ready.
*****************************************************************
If you have any other questios on preparation of the Java 2 exam please review previous postings I have made on Javaranch, .....
Thank you

The exam wasn't all that hard itself, but you have to be very careful about how you go about answering questions!!
Majority of the questions are Java source codes which ask you what an output will be when compiled or whether compilation of a code will generate a compile time or runtime error!
Basic underlying principles such as access control, passing object references as valus....etc will definitely be in the exam.
The trick is, if you aren't too sure about the answer to a question, look at the options given on the test and eliminate wrong answers to get to the right one!!
You are on the right track by using JQPlus, if you don't understand a concept, you could always bring the issue up in JavaRanch or direct your inquiries to JQPlus assistance, they will be more than willing to help out!!
Best of luck,

Hi everyone,.......
I took the SCJP exam, and passed with a 64%.Though I just barely made it, I can't wait to see my boss's face tomorrow, when I hand her a copy of my results. She never did believe I would pass, especially when my field of study is Business Administration, and Java is my first programming language!!
I wish to thank all those who have participated directly or indirectly in helping me pass the exam. Thomas Paul, you have been a great help, you really did clear some mis-conceptions I had on the fundermentals of Java Programming.

Tips on passing the exam

1) Buy a good programming book, I recommend the Java 2 Exam Cram, Second Edition by Bill Brogden
^^^ about 3-4 questions from his book appeared on the exam^^^
2) Do lots of mock exams and practise code.
^^^playing around with java codes helps, majority of the
questions asked aren't that complex, it only tests your
basic knowledge on Java. JQPLUS will definitely help.
I think, about 7-8 questions were from JQPLUS^^^
3) Make sure you visit Javaranch with any questions you may have or at least, view other people questions and try answering them by yourself.
^^^Javaranch helps re-assure your know-how in java or will
clear mis-conceptions on the principles of java^^^

I will be taking the Java 2 Platform Exam on Tuesday this week, and I am very nervous as a success will definitely open doors for me, in my present career, whilst a failure,......I don't even want to think about it!!
After repeatedly combing the Jqplus exam simulation, I am coming up with an average of 76%, while Java Round up gives me an average of 80%, I will be studing Marcus Green Mock Exam tomorrow and that's it for my studing!! I would be going through my revision study notes till the morining of the exam.
My question: is there any other relevant areas, other than the above mentioned, I need to cover before taking the exam? Any discussion or revision questions will be forthcoming!
Thank-you

NB: Comments and ideas can be emailed at muhammedo@hotmail.com
I have included some shift operator questions from JQ Plus which
I have troubles with. I know this should be a "breeze through" for the Gurus on this issue, but these questions have given me some headaches. Can anybody please make some comments on how the answers were derived
Question ID :952739435490
What would be printed during execution of the following program?
public class TestClass
{
public static void main(String args[ ] )
{
shiftTest(1, "A" ) ;
shiftTest(1<<31, "B") ;<br /> shiftTest(1<<30, "C") ;<br /> shiftTest(-1, "D" ) ;<br /> }<br /> public static void shiftTest(int i , String str) <br /> {<br /> if (( i >> 1) != (i >>> 1)) System.out.println(str) ;
}
}
***************************************************************
b, d Can you please explain the concept
***************************************************************
Question ID :955935425650
Consider :
class A {}
class B extends A {}
class C extends B {}
Which of these boolean expressions correctly identifies when an object 'o' acutally refers to an object of class B and not A or C?
***************************************************************
(o instanceof b) && (!(o instanceof a))
(o instanceof B) && (!(o instanceof c)) //correct
!(!(o instanceof B) | | (o instanceof c)) // correct
(o instanceof B)&&!((o instanceof A)| |(o instanceof c))
***************************************************************

Question ID :954698538220
Which statments about the output of the following programs are true?
public class TestClass
{
public static void main(String args[ ] )
{
int i = 0 ;
boolean bool1 = true;
boolean bool2 = false;
boolean bool = false;
bool = (bool2 & method1("1")); //1
bool = (bool2 && method1("2")); //2
bool = (bool1 | method1("3")); //3
bool = (bool1 | | method1("4")); //4
}
public static boolean method1(String str)
{
System.out.println(str);
return true;
}
}
*************************************************
1 and 3 will be part of the output?
Question:
*************************************************
Question ID :952739436700
What will be the outpout of the following program?
public class TestClass
{
public static void main(String args[ ] )
{
int i = 0 ;
boolean bool1 = true ;
boolean bool2 = false;
boolean bool = false;
bool = ( bool2 & method1(i++) ); //1
bool = ( bool2 && method1(i++) ); //2
bool = ( bool1 | method1(i++) ); //3
bool = ( bool1 | | method1(i++) ); //4
System.out.println(i);
}
public static boolean method1(int i)
{
return i>0 ? true : false;
}
}
*************************************************
it will print 2
*************************************************
Question ID :961883785420
What would be printed during execution of the following program?
public class TestClass
{
public static void main(String args[])
{
System.out.print(" "+(1<<33)+" "+(1<<32)+" "+ Integer.toHexString(1<<31) );
}
}
*************************************************
what will this output?
*************************************************

Thank you all,
......the concept is clear !!!
would it print "ok" at line #3 ?
I will definitely have to cover more material on this topic.
Have U got any URL's that could help?
Thank you for your response, it does make sense now!
What an easy concept! .....all I needed was to have the "wool taken off from my eyes" to see!!
Can you hed more light on the response I made for Thomas Paul the bartender, on the issue of passing a static variable to a non-static method. Does my code make sense?
Thanks for your reply,
the concept is clear to me,......i think !!!
To verify what you said, in a nutshell say:
public class Mohammed {
int a
static methodman(int b){
system.out.println("compile error" +a); //this won't compile
}
}
******************
******************
public class Mohammed {
int a
methodman(int b){
system.out.println("compile success" +a); //this will compile
}
}
************************
************************
public class Mohammed {
int a
static g
public static methodman(int b){
system.out.println("compile success" +g); //this will compile
}
}
