Hi!
Welcome back!
1. Would you recommend SCJWS 5 or 6? Based on what you recommend I already have SCJP (1.4) and SCWCD (Version 5). Do I meet the pre-requisite?
Always go for the latest: version 6. Yes, any version of SCJP is enough.
What are the study materials you would recommend? I already read few posts. I see that Mikalai Zaikin notes is default. but in his signature I see only Version 5.
It is good to read a few other posts in this forum as they give important tips. If you check the
ScdjwsLinks you will find a URL to MZ version 6 notes. Also note that there are still a lot of version 5 questions in the exam. It is better to read both.
Apart from that when it comes to important specs and articles you can find a nice sum up
here.
