Is the 1Z0-819 Exam Good News or Bad News?

Candidates are particularly anxious about the retirement of the 1Z0-815 and 1Z0-816 certification exams, especially the ones who have been preparing for them for a while now. As these exams would not be available after October 1st, 2020, many candidates would definitely panic. However, there is no reason to be worried about it!

As a matter of fact, the new 1Z0-819 exam would be a combination of topics covered in the two exams. So, candidates who have been preparing for 1Z0-815 and 1Z0-816 exams could easily pursue one single certification to become Oracle Certified Java SE11 Developer. Therefore, the 1Z0-819 certification basically simplifies the path for aspiring Java SE11 Developers.

The new 1Z0-819 certification exam would contain multiple-choice questions and candidates would get 90 minutes for completing the exam. The single certification could now help professionals showcase their proficiency in Java software development.

Changes in Exam Objectives

Another important concern that has emerged with the introduction of the new 1Z0-819 exam is the change in exam objectives. Candidates should be prepared well for a difficult exam because of the broader range of topics covered in the exam. Candidates should also know about the fact that 1Z0-819 certification has also excluded certain topics from the 1Z0-815 and 1Z0-816 exams. As a result, there is no need to study the following topics for their 1Z0-819 certification preparation.

  • Execution of a basic program with the help of command line, modules being an exception
  • JDBC CallableStatement
  • Java characteristics such as backward compatibility, platform independence, and others
  • Java Assertions
