Hi

Right now, I am learning Java and preparing for SCJP.
I am completely new to J2EE, and I request you to let me know the best order of learning the technologies like Servlets, JSP, Javascript, EJB, XML, JSF etc one by one.

Hi

Is it possible to get 90% score in SCJP 1.4 without going through Java API Documentation and Java Language Specifications?
Question : An Interface can never be private or protected.
Answer: FALSE

That means an interface CAN BE private/protected. But I got a compiler error declaring an interface which is private/protected. Are there any other occasions where an interface can be declared private/protected?
If a checked exception is thrown in the catch block, it MUST also be declared. If a checked exception is thrown inside a method, it must EITHER be caught in a try catch block OR declared. But what happens if we both declare AND catch a checked exception(thrown in a try block and caught in a matching catch block)? Does it generate a compilation error? Should the methods calling the present method declare/catch the exception thrown in the present method?
Is there a book for SCJP 1.4 by K&B??
Hi

I am about to write SCJP 1.4 on June 4th. So far I have referred to only Sybex Complete Java 2 Certification Guide . Recently I came to know about K&B book. Here are my doubts:-

1)"SCJP Sun Certified Programmer for Java 5 Study Guide" by K&B, Is this book for 1.4 or 1.5?
2) Will I be able to digest this book in 15 days? (I have already digested Sybex book.)

Please suggest.
class Test5
{
public static void main(String args[])
{
String s="First";
System.out.println(s);

s="Second";
System.out.println(s);
}
}

The output is : First
Second

How and why is this possible if Strings are immutable?
Do you mean a factory class can be used as a base class, from which required classes can be derived?
Book says java.util.Collections is a factory class. What is a factory class at all?
