Hello, I am thinking about which certification is better to take if I don't have anyone. In the past fail de Java 8 Certification I didn't studied well.
Do you recommend first take Java 11 1Z0-819J or Java 17 1zo-829?
Sorry for delay in replying. Practice for the exams, use mock tests, and sit whichever exam you think you will get the better mark in. If you pass 829, there is maybe no point in sitting 819 at all.
Take the exam you have the study materials for. If you haven't bought yet, I recommend skippingt eh 819 and going straight for the 829. There isn't a huge benefit to taking one exam when you already passed the other.
