The percentages tell you where the exam concentrates its questions, so budget your study time accordingly — the complete outline above lists every domain and subtopic.

The Oracle Java SE 8 Programmer II (1z0-809 Korean Version) is Oracle's official exam for the Java SE certification, positioned at the Professional level. It is the credential hiring managers scan for, and passing it proves your skills meet the vendor's own standard.

The official registration fee is $245 USD, and you will need 65% to pass.
