Please suggest me that should i go for SCJD or SCWCD .Which certification has more industry relevence. Currently i am working in an MNC, has more interest in Core Java . I have cleared SCJP 5.0 in Jan09.
I advise you to take SCJD first, if you current work is not related to web programming (Servlets/JSP).
This exam will give you a lot of core knowledge in Java and a good code writing experience.
In my case, I took SCWCD first, because I'm a web programmer and I'm working with JSP/Servlets/Struts etc.
SCJP 6.0(95%), SCWCD 5(94%), SCJD (working on B&S v.2.3.1)
It all depends on what the purpose of the certification will be. If you are going for a job change and want to do web programming (jsp & servlets) definitely go for the SCWCD. If you want to prove you are a good (or excellent) java developer then do the SCJD.
When you have taken SCJD you have to wait 4 to 6 weeks for your result, so in that period you can go for the SCWCD
I am a web developer and I am taking SCJD first. I believe that having the core Java knowledge is more important. I see my co-workers, most (if not all) of them do not have basic understanding in Java and write and design codes without considering properly what a developer should consider.
And still, I am learning a lot such as RMI, threads, locking and etc.
