Sun Certified Practice Questions

1. I found the UCertify site to be rather helpful for getting some exposure to the Sun Certified test. They allow you to download a practice exam and you have the option to review your answers either right after you answer each one or at the end of all the questions. However, there is a fuller version that you have to buy in order to get the full benefit of what they offer. It is a bit of a teaser, but you do get a chance to see what kind of questions are asked on the exam.

2. This website is from the about.com site and they give you 29 questions to answer and they also provide several other links to other free Sun certified practice questions. I liked the simplicity of the site and the variety of the questions they asked.

3. Javacertificate.com provides sample questions for the Sun Certified exam and after each question they let you know how many questions you got right or wrong and tallies them as you proceed from question to question. They also let you know how much time has elapsed. I find this gives a better feel for the real exam and you get to see how well you are doing after each question.

4. Geocities offers a 30 question practice exam and they also give you answer with an a brief explanation why that is the correct answer. There is a drop-down window that allows you to skip to another question. You write down your answers on a piece of paper and you can check to see how many you got right. Overall, this is a good site, but you do have to get additional resources in order to write your answers down. There is not an option to answer on the computer.

5. Javaprepare.com offers a number of options on their site that can prepare you for the Certification exam. They offer two different test, FAQ, and a tutorial to help you better understand the Java language. They have charts and go into some detail about the Java language. This site is a wonderful complement to preparing for the Sun certified exam. I really like all the information they give you. Check it out!

Java Virtual Machine

The Java Virtual Machine (JVM) allows the Java program to be run on any platform or operating system. It is a set of computer software programs that protects users from malicious software by running them in a virtual environment. This allows for great portability from one system to another.

Java API

The purpose of the Java 2 Platform SE 5.0 API is that it lists all the packages, classes, methods, constructors, errors and obsolete code that is available for use in the Java language. It is quite extensive and is a great reference tool to help with programming in Java. When looking at a specific class it is further broken down in a tree format and continues to branch out as you find the specific method you want to employ in your code. This is a powerful tool that helps the novice user to Java and the seasoned Java programmer to access an array of commands that would be virtually impossible to memorize.

My History

My name is Hassien and this is my first time learning Java. I have just recently completed the C++ class. Right now I am studying to become an electrical engineer, but I am starting to rethink about going into some IT field. I am hoping that after this class it will really help me to decide if I want to continue engineering or go into the IT field.
