JavaBlackBelt - What is your Java Belt ?

It has been ages since I last took my Java exam. Recently I was looking at JavaBlackBelt. JavaBlackBelt is a community for Java and related technologies certifications.

It seems that a lot of people have contributed to the exam question pool. I took the beta exam, and it really test your in-depth knowledge of Java. For those of you who want to test your Java skills, give it a try, and it is free !!!!

What are the different views that are considered when building an object-oriented software system?

What are the differences between aggregation and composition ?

1: String a = “test”;
2: String b = a;
3: String c = b;
4: String d = c;
5: a = null;
6: d = null;

Which objects are available for garbage collection?

Interestingly, so far there is no one who get the Black belt. Maybe it is really too tough, or the real hard core Java programmers never bother to take any certification ?

There are different levels of the belt, start with

  1. Yellow Belt
  2. Orange Belt
  3. Grenn Belt
  4. Blue Belt
  5. Brown Belt
  6. Black Belt

Most are in the Yellow Belt, and 0 for Black Belt. I am wondering who will be first Black Belt :)

For those Java programmers out there, find out how much you know about OOP and have fun !!

    Brown belt. It is not yet possible to get a black belt since the Programming Exams have not been released yet.

    I have found this site incredibly useful, and I hope to take the SCJP sometime next year thanks to JBB!

    i think that game is stupid, sorry but you need to make your own questions to even get a change to go for higher belts. Sometimes i check out beta tests and that pretty much it. I think they should remove the belt system since it means nothing or they could create system for people that are not into creating questions.

    ps. what i meant is that if you are forced into making questions those questions will be bad. Congratulations to higher belts, get a life.

    Hi Raveman.
    You are just right :-)
    In a next version of JBB, you’ll probably be able to go up to the green belt without contributing.
