I passed my SCJP6 certification in 2014.
I took a break in my IT work in 2016..
Planning to resume back this year.
Kindly suggest Java Certification which I could write in short term
Also some tips and guidelines for clearing it
Technically, if you have already passed SCJP 6, you are eligible to take the OCP Java 11 upgrade exam 1Z0-817. This exam is substantially easier than the full blown OCP Java 11 Part 2 (1Z0-816) exam.
But you will have to prepare for it without a book because there are no books for it at the moment. (We have mock exams for it though).
If you don't want to learn Java 11 stuff, you can also go for OCA JP 8 1Z0-808 and then OCP JP 8 1Z0-809.
I have done a humble and sincere work to help all those who are preparing for the Java Certification. Check it out
