• Identify the components required to connect to a database using the DriverManager class including the JDBC URL
• Submit queries and read results from the database including creating statements, returning result sets, iterating through the results, and properly closing result sets, statements, and connections

Localization

• Read and set the locale by using the Locale object
• Create and read a Properties file
• Build a resource bundle for each locale and load a resource bundle in an application

Practice tests are randomized to give a real examination feel. All topics listed above are divided appropriately in 6 tests consisting 90 questions each i.e., 540 questions in total. Questions are designed based on real examination questions in terms of pattern and complexity. All Exam topics and sub-topics are covered.

Explanation of all the correct answers is also provided for reference and understanding. Relevant hints and how to approach a question in real examination setting is also provided in explanation.

Successful completion of all the tests will boost your confidence to attempt Oracle Certified Professional -Java SE 8 Programmer II examination.

More information on detailed curriculum and assumptions to be followed for examination are available on oracle certification page.

NOTE: Each practice test of this course contains questions on all the exam topics, similar to what is expected in real exam. But if you prefer to solve topic-wise questions, then enroll in my other course titled “Java Certification – OCP (1Z0-809) Topic-wise Tests [2022]”, which contains the same questions arranged in topic-wise manner. 

Disclaimer: These questions are not real examination questions / dumps. These questions  are created to evaluate your preparation for certification exam. 

So, grab a cup of coffee or your favorite drink and test your Exam Preparation.
