The Oracle Certified Professional: Java SE 11 Developer (1Z0-819) is a single, comprehensive certification exam that validates your proficiency in Java Standard Edition 11. 

It covers a wide range of topics, including Java fundamentals, object-oriented programming, functional programming, modules, concurrency, I/O, JDBC, and security. 

This exam replaces the earlier two-part certification exams (1Z0-815 and 1Z0-816) and is designed for developers aiming to demonstrate their expertise in Java SE 11.

The 1Z0-819 exam is intended for individuals seeking to earn the Java SE 11 Developer certification, regardless of their prior certification status. 

In contrast, the 1Z0-817 exam is an upgrade path specifically for those who already hold an Oracle Certified Professional (OCP) certification in Java SE 6, 7, or 8, allowing them to update their credentials to Java SE 11. Notably, Oracle has announced the retirement of the 1Z0-817 exam as of November 30, 2021.

Effective preparation for the 1Z0-819 exam involves a combination of study materials and practice:

  • Practice Exams: Engage with gamified testpreps to familiarize yourself with the exam format and identify areas for improvement. 
  • Online Courses & Labs: Enroll now to access structured learning paths and hands-on lab activities to reinforce your understanding.
