Yes, without any doubt. Certification puts you on top of the list of all candidates. Employers see a lot of value in certifications. Only thing to be considered is that certifications dont replace real experience in job. By that I mean,there are people who might have no certification,but couple of years of experience which is also as good. For you, since you are trying to get into job market, a certification as SCJP will definitely will make you a great candidate to look at. Besides since you are not working , you can prepare full time for this exam and clear it without much stress . Still it would take practice & good preparation.
