The Sun Certified Developer for Java 2 Platform (SCJP 5.0, exam number CX-310-055), the latest certification exam from Sun Microsystems, Inc. is for developers experienced in Java programming language. This certification validates a developer’s understanding and familiarity with the basic syntax and structure of the Java programming language. It also proves a developer’s ability to create Java technology applications that run on server and desktop systems using Java 2 Platform Standard Edition (J2SE) 5.0 (“Tiger”).
The J2SE 5.0 release focuses on certain key themes like ease of development, scalability and performance, monitoring and manageability, and Desktop client.
The SCJP 5.0 certification consists of one exam and serves as a prerequisite for several other Java technology-related certifications like SCWCD, SCBCD, SCDJWS, and SCMAD.

To test the candidate on knowledge of declarations, access control, object orientation, assignments, operators, flow control, assertions, Sun made a new version for SCJP exam recently.
The new version, SCJP 1.5 exam, made the exam more difficult than the previous versions, it added more objectives and new questions to the actual questions and promote the passing score to 59%. However, the candidate need not to worry too much, no matter how the exam changed, it should be a designation that indicates excellent knowledge of the Java spec; as it always does. To compare the changes from the following guideline we list for you, and master all the knowledge, it will be easy for the candidate to pass the exam:
How is the SCJP 1.4 exam different from the SCJP 1.2?
Exam objectives: AWT and IO have been dropped. Assertions and Wrapper classes have been added. A deeper understanding of the Collections Framework is required (e.g., using hashCode and equals).
Number of questions: 61
Time: 120 minutes (same as 1.2 exam)
Passing score: 52% (reduced from 61%)
Level of difficulty: Sun indicates that it is more difficult.
Format of questions: As on the 1.2 exam, most questions (an estimated 80-90%) still have code samples 6-30 lines long. Multiple choice questions may have more than 4 options, but you will always be told how many options to choose.
How is the SCJP 1.5 exam different from the SCJP 1.4?
Exam objectives: Several important new language features have been added, including enums, generics, static imports, and autoboxing/unboxing. API features added to the exam include java.lang.StringBuilder, java.util.Locale, java.util.Formater, java.util.Scanner. java.util.regex.Pattern, and java.util.regex.Matcher. Java IO features have been added, including File, BufferedReader, BufferedWriter, FileReader, FileWriter and PrintWriter. Concepts such as loose coupling and high cohesion have been added, as well as greater emphasis on encapsulation as it relates to JavaBean conventions. Bit manipulation (e.g., shifting) has been dropped.
Number of questions: 72 (increased from 61)
Time: 175 minutes (increased from 120 minutes)
Passing score: 59% (increased from 52%)
Level of difficulty: The concensus is that it is more difficult.
Format of questions: As before, you will always be told how many options to choose. No credit is given for partial answers.
Will there be an exam for version 1.6?
Sun has made no official announcements regarding an SCJP exam for version 1.6, so no one really knows. (Note that there was no SCJP exam for 1.3.)

What is the best way to prepare for the SCJP exam?
Familiarize yourself with Sun’s exam process, including objectives, registration, testing, etc. See Sun’s SCJP page for details.
If you are new to Java programming, start with a good introductory book such as Head First Java or Thinking in Java. Check the JavaRanch Bunkhouse for additional recommendations and reviews. Refer to the API documentation and the Java Language Specifications along the way. (See links in this FAQ.)
Once you have a foundation, study at least one good (and current) certification preparation book. (See recommendations in this FAQ.)
Use the SCJP forum to post questions, and reinforce your own understanding by answering other people’s questions.
Take as many mock exams as possible. (See links in this FAQ.) Use these to determine where additional study is needed, and as a guide to when you are ready.

In my dark and horrid past, I ran an organization that prepared newcomers for the Java Cert exam. As such, I have some insight you may find useful.
Go through one book at a time, don’t skip around between books because it will confuse you. Specifically with regard to the certification objectives, areas like Threads may be taught differently in different books. As such, its best to have one teacher at-a-time instead of numerous. Learning it multiple ways AT THE SAME TIME, will lead to confusion.
If you’re brand-spanking new to Java, don’t go directly to a Java Cert book. These books were not created for beginners, they were created for people who understand the basics of Java programming. Instead, spend a month or so getting to know the language with a “Learning Java” type book. If you are new to programming altogether, you may want to precede the learning java type book with a basic computer programming book.
Code Code Code. There is a lesson to be learned in every code example of every book you read. Learn the lessons and learn to code at the same time. The difference between someone who has spent the time to code and someone who is merely memorizing answers is immediately apparent in thier test progress. Someone who codes regularly will quickly pick-up on the intricate questions being asked on the exam. Someone who is memorizing answers will get lost easily once the questions deviate from what they’ve memorized. On the job, the memorized-no-coding person will be quickly fired, while also proving the test to be inneffective in the minds of the employer who f/hired them.
Study with friends. There’s an old axiom that goes: “if you put 100 programmers in a room and give them 1 problem, you’ll get 100 different answers, and most will work.” By studying with others you’ll be able to see how others approach the questions and exercises you’ll be studying. When I study for a certification, my initial approach to a problem is rarely the best one. But if I’m studying with others, I can see many approaches and find out which one is best for me.
Use Mnemonic Devices. The thing about memorable mnemonics is that they help put information into your long-term memory instead of your near-short term memory. This means you won’t be “brain-dumping” your newly learned lessons after the test. My favorite mnemonics are acronyms. Its amazing how memorable a lasciviously written acronym is. Make ‘em dirty to make ‘em last.
Don’t try to learn the entire language in a week/month, take your time. There’s the French cognitive psychologist name Piaget who postulated that adults learn sequentially and cumulatively. Basically what this means is that before you can learn how to write an inner class, you first need to learn how to write a regular class. You can try and skip right to the inner class if you want, but you won’t learn the “whys” of it. Its just as important for us human beings to learn the background of something as it is to learn the thing itself. Now, if you’re a martian, venusian, or uranusian, that may not apply. if you are a venusian learning Java, I say welcome to our new Venusian Overlords!
Learn “why” something works a given way, not just that it works one way. Other psychologists have postulated that there are three stages to learning. There’s recognizing something, rote memorization, and being able to create something new from your memorized material. This is usually applied to the learning of human languages, but it applied to Java Certification prep as well. Here’s how they differ. Being able to recognize that something is written in Java is nice, but you have to know how to use the language also. Recognizing but not really being able to use is the first level. Not really useful. Being able to recite all parts of the Java Language is certainly better than just recognizing it. Unfortunately, being able to recite the number of bits in an Integer doesn’t mean you’ll be able to use it in code. Finally, being able to create algorithms in the language, that’s where you want to be before you take your Sun certification exam. That’s what employers are looking for. That’s why K&M ask you questions that make you think. And that’s why the people that can use the language most effectively are the ones who don’t get laid off.

Apart from the programming questions one should also concentrate on the theory (encapsulation…) also. As the basic theory questions would also have the same weightage.
