  Oracle does not have to pay for a redirect. You will need to submit a request to http://bit.ly/f39Dny to send them. Please provide an address where the kit can be delivered.

• 'View history of Pearson' does not show old Prometric Certification SCJP 1.4

  Hello
  
  A few weeks ago, I received a message from the Oracle a few little steps to migrate my data from certification Prometric to Pearson VIEW. I did it and for a few weeks, I could check my old Prometric Certification as a Sun Certified Java programmer SE 1.4 in the history of the 'view' on the Pearson VIEW Web site. But since last week I don't see anything at this point of view.
  
  Anyone know what is happening?
  
  See you soon,.

  The key point is what you see:

  http://certview.Oracle.com (which is Oracle and not Pearson VIEW)

  Is your certification?

  References must indicate your certifications should be migrated, but your story for review will not (in most cases).

  Recent posts on http://blogs.oracle.com/certification contain bits on it, this thread {threadID = 2220819} while perhaps not relating to your case has a bit of history

• Apprenticeship Weblogic

  Hi master Weblogic,
  
  I am interesting to aim for Weblogic Sysadmin. I have no idea where to start with and.
  
  My question is that I have to have fundamental Java to learn about it.
  Do I have to take a certification as SCJA (* not even required *).
  This in relation to my question to vs SCJA, SCJP
  
  Please share your opinion.
  Thank you

  Knowledge of Java at the level of the SCJA is good start, but I have my experience, you should know
  more than that.

  It is very convenient if you build yourself a Java EE application that uses things like connection pooling
  Java messaging, EJB, servlets etcetera. In fact, to build your application in the context
  of an application server (for example, WebLogic), that is, the server manages a large number for you (life-cycle management,
  transactions etc.

  In my opinion a lot of Java knowledge (experience) will help you understand the underlying mechanisms
  a server, such as WebLogic server.

  You probably have a lot to learn, but I think it's going to be a learning path very interresting for you.

• Please explain this issue

  Hello

  I'm prerparing to SCJP.

  I got this question

  What will be the result of the program?

  {public}
  public static throwit Sub)
  {
  System.out.Print ("throwit");
  throw new RuntimeException();
  }
  Public Shared Sub main (String [] args)
  {
  Try
  {
  System.out.Print ("hello");
  throwit();
  }
  catch (Exception)
  {
  System.out.Print ("taken");
  }
  Finally
  {
  System.out.Print ("finally");
  }
  System.out.println ("after");
  }
  }

  A.	Hello throwit caught
  B.	Compilation failure
  C.	Hello throwit RuntimeException captured after
  D.	Hello throwit finally after What is treatment and why. Please explain

  answer would be D.

  car-

  The method main() correctly handles the RuntimeException in the catch block catch finally runs (as it always does), and then the code returns to normal.

  A, B, and C are incorrect based on the logic of the program described above. Don't forget that properly handled exceptions do not cause the program to stop execution.

• Advice from professionals for the amateur of the MNA

  Hi everyone I hope you have all had a good Christmas and new year.
  
  So my profession is not software engineering and civil engineering (roads, infrastructure, structures, etc.), but I spent years teaching java in my own time and passed the SCJP return in 2010 (I found it an excellent tool to guide me on what to learn and make me learn things that I might not have otherwise). I find java a very useful tool for the work and studies (including my independent study of the year last for my degree).
  
  Even though I am a self-taught amateur, I am well aware, there is a difference between knowing the fundamentals of Java and know how to establish a solid piece of software, and although I got by ok so far, I would like to take my skills to the next level.
  
  I had in my mind to make the developer Java SE 6 after I went SCJP 6 but of course Oracle bought Sun and brought in training required Oracle as part of the requirements. Although I would be happy to make the training realistic I can't afford or justify the formation of my back but I did not like the noise of the [development Applications with the Java SE 6 platform | http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=609 & p_org_id = 28 & lang = US & get_params = dc:D61860GC10] [, p_preview: N] training, because not only that looks like it covers tips for Developer certification (incase I decided to do), but it would apply the stuff to improve my skills.
  
  I have looked everywhere for similar resources such as books, but have not been able to find anything too convincing. I know that I can not actually real-world experience to learn some of these skills, so my question is did anyone know books or countries that would help someone like me? Give me advice of best practices for the creation of good quality java software?
  
  Thank you.

  We will here my two cents worth:
  Roughly speaking, there are desktop development and development based on the web (there are others). I think that the market for web-based development work is much bigger and I would recommend this path rather than office development. If I understand correctly, web development is divided into browser-based applications and mobile device applications. I'm a developer of browser and I will only talk about this.

  There are countless frames in use for the development of browser based applications. I suggest stick you with the more commonly used ones and not ones that few have heard of (especially employers). Some technologies you should finally become familiar with is: JSP, JSF, Servlets, JDBC, Hibernate, JPA, Struts, Spring, Ant, Maven, JEE6 stack, XML, Web Services, etc. You can read about what these technologies do before you decide you want to read about in detail.

  Some of these technologies are old (JSP and Struts to name but two), but countless programs have been written in them and you'll probably sooner or later (more probably more sooner) find a job where you have to debug and improve their. Since you seem to have web experience and if you consider taking this route, I suggest that you get a book on JSP/Servlets and read online on JDBC. Create a web application that reads data from a database table, it displays and allows the user to update data using MVC design (many web applications rely on filling out the forms). Add validation. Then refactor the project again and again to get it looking for professionals. When you have that down Pat, I suggest you go on JSF. You can optionally enter the spring (I would avoid Struts), but that's a topic for a later date.

  I have read many books on different technologies, as the years have not met all that will take you step by step on setting up of a professional web application of complete best practices from scratch with just about all the services, you must generally. I guess that nobody does because each new requirement of web application is rather unique so that the authors prefer not to give an example of design while there are countless services and configurations of services. In addition, their example probably wil become obsolete soon enough.

  Finally and above all:

• Good book for certification OCJP

  Someone suggest a good book that I can use for certification of ocjp 6
  
  Thank you
  Sam

  Just FYI, you can look at the Java code ranch communities SCJP forum for experiences of people with certification for other valuable information about the exam.

  https://www.coderanch.com/how-to/Java/SCJP-FAQ

  And to start with SCJP, you can follow BOOK BY SCJP Kathy Sierra and Berta Bates who has good material for SCJP.

  Here is the link to the book on amazon

• Reviews of Java

  Hi, I am looking to acquire a Java programming skills. I bought the book SCJA (exam CX-310-019) that I expect this exam, but looking at the Oracle site there now seems to be no mention of the SCJA and instead, they have a qualification Oracle Java. As Oracle and Sun are now, I don't know what test I take (or even those who is still available to take).
  
  Should I watch the SCJA, or should I rather watch exam 1Z0-850 (Oracle associated Java SE 6)? Or maybe even the new route to 7? I don't really know which is the best test to work. Can someone provide advice?
  
  Thank you.

  Hi, welcome to the forum!

  Sun Certified Java Associate certification is now Oracle Certified Associate Java SE certification.

  I suggest you take the exam 1z0-803 (Java SE 7 programmer I have), because this is the real exam, and after that with more study and practice, you might consider taking the exam 1z0-084 (Java SE Programmer II).

  The book you have (for the review of the CX-310-019) covers the same objectives that the exam 1z0-850, but you might study with her and see what has changed in more recent reviews.

• OCMJEA: course mandatory participation requirement if you have previous cert.

  Now Oracle Certified Master, Java EE 5 Enterprise Architect, to a required course. The list of courses for this certification is: (among others)
  
  Java: Java SE 6 programming language
  Development of Applications Java EE 6 platform
  Database of Building Applications with JPA-based
  Business development component with the EJB technology, Java EE 5
  Business development component with the EJB technology, Java EE 6
  Creating Web Services using Java (TM) technology
  Development of Applications Java EE 5 platform
  EJB 3.0 technology workshop update for Version 2.x developers
  Development with Servlets and JSP, Java EE 5 Web component
  Component development with Servlets and JSP, Java EE 6 Web
  Java programming language
  
  But some themes of these required courses are included in other certifications, for example:
  Oracle Certified Professional Java Programmer
  Oracle Certified Professional, Java EE 5 Web Component Developer
  Oracle Certified Professional, Java EE 5 Business Developer components
  
  The question is, if you have one of this certification and want to prepare the review for Enterprise Architect Java EE 5, it is necessary to do an internship?
  
  For example, if you are an already Oracle Certified Professional Java programmer Java SE 6 and you want to prepare the review for Java EE architect, why must be necessary do an internship as "Java, Java SE 6 programming language"?
  
  
  Kind regards.

  Then bad news, I'm already cerficate like SCJP Java SE 6, SCBCD Java EE 5 and SCWCD Java EE 5 and none of them are me.

  It seems that most of the courses that I could do, besides being more expensive, have as prerequisites did others, for example, if you want to follow the course [Object-Oriented Analysis and design using UML (OO-226) | http://Education.Oracle.com/pls/web_prod-PLQ-Dad/db_pages.getCourseDesc?DC=D61808GC20]

  I have to do before [programming language Java, Java SE 6 (SL-275-SE6) | http://Education.Oracle.com/pls/web_prod-PLQ-Dad/db_pages.getCourseDesc?DC=D61748GC10] and so on...

  In this case, for example if I want to purpose and design-oriented analysis using UML (OO-226) should do the programming language Java, Java SE 6 (SL-275-SE6) before?

  Very bad news in Oracle.

  If you were already a LDCM then 1z0-868 would be sufficient, and no training not required (http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=326).

  In the case of courses have prerequisites in practice this as take to be the standard of something that took the pre-requisitie training course.
  For example, I want to take (Object Oriented Analysis and Design using UML (OO-226)) I could fight with this course because I am not at the standard of knowledge of a person who has aken the course of Java SE 6.

  So, if you're a SCJP Java SE 6 your standard expected of course people for you to follow this course.

  The purpose of the pre-requisite course are for you have sufficient training for the course and be able t keep up with it... a student with insufficient experience would fail to follow and would slow down the whole class... which is not good for everyone.

  Very rarely a seller of Oracle, try to demand a pre - req courses is taken... but it should not happen if you can demonstrate sufficient prior knowledge.

  Incidentally, I'm not in Oracle and not authority, and I'm a little less familiar with Java Certifications.

• Manual MCYS

  Dear friends,
  I spent scjp with 90% of the brands. Now, I am planning to take a cert MCYS. Can someone tell me which are the best references available?
  
  Edited by: Caarmel may 4, 2011 11:05

  The MCYS cert or what it's called now, the Oracle 'Certified Master, Java SE 6 developer' is a project based certification. Once you register for the test, you will be able to download the specifications. You will have then the 12 months following the date of purchase for the realization of the project in accordance with the specifications and defend your design in a test.

  Given that you have passed the SCJP exam, you should be very familiar with the Java language. Now it's time to really dig into the application design. I would recommend "[url http://www.amazon.com/First-Design-Patterns-Elisabeth-Freeman/dp/0596007124/ref=pd_ecc_rvi_cart_1] head first Design Patterns". It has a very different style of presentation of material, but it gets across concepts well in my opinion.

  You must also as a good reference book "[url http://www.amazon.com/Professional-Java-JDK-Clay-Richardson/dp/0471777102/ref=sr_1_5?ie=UTF8&qid=1304639450&sr=8-5] professional Java JDK 6.

  I mean, look at the description of the [url http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=41&p_exam_id=1Z0_855] developer assignment on site of the Oracles and creating applications similar to what we call the practice. Using what you have learned about design patterns and the book of reference help create several application examples. Then try to write a brief explanation of why you designed they way you did. Once you feel confident, the exam. You have 12 months to complete the project from the date of purchase, so you will not have much time.

• What is the best way for a J2EE developer with oracle?

  Hello
  
  I am a J2EE developer, for the moment I'm working in a commercial bank as an enterprise application developer. Java, I learned when I was following a degree of local COMPUTER and with the help of books, work at my place of work and the internet, today I develop applications with JSP, Servlets, JSF2.0, EJB3.0 and third-party J2EE part libraries JSF etc (I also develop software using other programming languages such as Asp.net, c# .net, etc. WPF, but I prefer to be in the path of java). Other than that, I also work as the designer of the user interface of most of our applications.
  
  I have the skills and practice after having worked for 4 years as a developer of web/enterprise applications & UI designer, but now I have to focus on some grades of paper and so I do BCS.
  
  Now, I want to be a professional in the Oracle java path, and I need to know what is the best way, I choose to go with Oracle. I finished my SCJP courses, but did not take the exams, because there were rumors that Oracle will clear these reviews in the future. I am interested in Oracle university, but I'm unable to even think about it as I live in Sri Lanka and is not only a large part of the wealth to go to the USA and join.
  
  So I really appreciate if any professional Oracle could suggest me the best educational path based on what I mentioned about my technical and professional training. Because I have a dream to join Oracle a day as an employee and be a good contributor on the same forum, which I get help today!
  
  :-)
  
  Thank you!!!

  As you can see on our Web site, Oracle did not retire Java certifications. You can browse through the available certifications and I hope to help determine your path.
  http://education.Oracle.com/pls/web_prod-PLQ-dad/db_pages.GetPage?page_id=140

  SCJP became Oracle Certified Professional Java Programmer. You can find more information on these reviews on our site here: http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=320.

  Concerning training, virtual training live might be an option for you. You can find more information at http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=233.

• question on the GC in Java

  Given

  Given:
  3. class Beta { }
  4. class Alpha {
  5. static Beta b1;
  6. Beta b2;
  7. }
  8. public class Tester {
  9. public static void main(String[] args) {

  15. a1 = null; b1 = null; b2 = null;
  16. // do stuff
  17. }
  18. }

  Why there is 1 single object will be eligible for GC. I need an explanation claire pls

  It is not a duty. It's the SCJP practice test.

  However, as you try to learn, you will learn better if you think that it through as much as possible, post what you think and why and get feedback on that, rather than just a question for the answer.

  Objects how you qualify and why?

  Thank you for your joy. First of all, I have rename the variable Alpha object instance. now, I have

  Given:
  3. class Beta { }
  4. class Alpha {
  5. static Beta x;
  6. Beta y;
  7. }
  8. public class Tester {
  9. public static void main(String[] args) {
  10. Beta b1 = new Beta(); Beta b2 = new Beta();
  11. Alpha a1 = new Alpha(); Alpha a2 = new Alpha();
  12. a1.x = b1;
  13. a1.y = b1;
  14. a2.y= b2;
  15. a1 = null; b1 = null; b2 = null;
  16. // do stuff
  17. }
  18. 
  

  I have a stack containing a1, a2, b1, b2 and the pile is containing 2 objects of type Alpha, 2 objects of the beta type, x, y *(AM I RITE AT HERE) *.

  Yes. Note that x and are among the two objects of Alpha.

  On line 12 and 13, the instance y variable and the class variable x class Alpha point to an object of class b1 Beta.

  Close. The instance y variable to one of the Alpha (not of the Alpha class) and the class variable x of class Alpha point to a Beta - the same beta object that is indicated by b1.

  On line 14, * instance of variable y * points to an object of class Beta b2.

  Variable y of another Alpha object instance pointing to the second Beta - the same object as that is indicated by b2.

  Note that there are two variable y (one for each Alpha object) and a variable x (a for class global Alpha). It's the difference between an instance variable (non-static member) and a class variable (static member).

  Finally, at line 15, a1, b1, b2 are set to null.

  Well Yes.

  Therefore, I think that there are 2 items that are eligible for GC (1 object of type Alpha and beta type 1 object)

  Well, let's see.

  A1 is null, then nothing no points to the first Alpha, GC-able. In addition, y of this first Alpha is more advanced on the first beta version, so if you think that this makes this inaccessible Beta. However, the class variable x (which is not specific to an instance of Alpha) always points to the first beta version. So far, a single GC-able object.

  B1 is zero, so it is more pointing to the first beta version, but still Alpha.x points to the first beta version. Still a GC-able object.

  B2 is zero, so it is no longer points to the second Beta, but Alpha is second again is the case, then the second Beta is always accessible. Still a GC-able object.

  Remember, there are two variables y - one for each instance - Alpha - and one variable x a for class Alpha as a whole.

  Part of what makes this confusing example is that they followed a syntactically legal approach but bad practice to use a reference variable to refer to a static class member, rather than the name of the class.

  a1.x // legal, but confusing
  Alpha.x // preferred
  
  a1.y // the only legal way
  Alpha.y // error, won't compile -- how would the compiler know WHICH Alpha instance's y variable we mean?
