Welcome to Javaranch, there is one and only book that almost everyone would recommend, it is Kathy Sierra and Bert Bate's "Sun Certified Programmer for java 5 study guide". If you have already done some java programming and are aware of little object oriented concepts, this book alone will do. Dont forget to check out FAQ link in the signature below. Good luck.

You have to buy "SCJP 1.5 exam guide by Kathy Sierra, Bert Bates". It is a very good book.

Lot of Mock exams are available in net. you can workout for as many as exams as possible.

eg. http://faq.javaranch.com/view?ScjpMockTests

All the Best.

Hello Sneha,
Like everybody, I will also suggest you to go for K&B book. It is an excellent book, if you have some experience in Java. I recently cleared SCJP. Read the book atleast twice. Solve all the questions that are given in self test. When you are confident enough, go for mock exams availble on net. And always feel free to ask any(relevent) question on Javaranch. You will definitely find answer here in Javaranch.

Thanks! for suggesting me regarding the study material.

Please anybody explain me the fallowing increment operator example?

class Increment
{
public static void main(String []args)
{
int i=0;
i=i++;
i=i++;
i=i++;
i++;
System.out.println("i= " +i);
}
}

Hi Sneha!
You could have posted this question into another new thread, as this one goes under the subjectline "Regarding SCJP". May be you can explore more of Java Ranch policies here.

Coming back to your query, it is "pre-increment expression" as the name suggests... it says "use the value of the expression before the increment happens". So the expression

i++

says 'use the value of i before it is incremented'. That way,

i = i++;

gets evaluated to

"i = 0";

Remember this expression "i=0" has not been executed yet. It would remain as it is and get evaluated after the increment has happened.

Now the increment happens, i from 0 becomes 1(somewhere in memory);
and after that the expression is evaluated, i.e.

i=0;

so i becomes 0 again.

Try excuting the following code,

    
int a = 0;
int b=0;
b=a++;
System.out.println(a);
System.out.println(b);

int x=0;
x = ++x + x++ + x-- - ++x + x++ + ++x;
System.out.println(x);

I have bought SCJP book by Khalid Moughal. Is it a good book? Or is Kathy's book is better than this book?
