| There are four main certifications, all from Sun (but conducted by various testing corporations). There is the J2SE programmer and developer tests, and their equivilant in J2EE. Last time I took one it was $150 a pop. Best way to study for them is to get sample tests, as you get a feel for the kind of specificity they're looking for.
They will look good on a resume, but I don't think that they're anything career-shaping. I've never seen a job requirement "must be certified in Java". |
