Use parallel Streams including reduction, decomposition, merging processes, pipelines and performance.
Building Database Applications with JDBC
Describe the interfaces that make up the core of the JDBC API including the Driver, Connection, Statement, and ResultSet interfaces and their relationship to provider implementations
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
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. 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 11 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 (1Z0-819) Topic-wise Tests ", which contains the same questions arranged in topic-wise manner.
Who this course is for:
- Students preparing for OCP (1Z0-819) Certification
- Programmer want take OCP (1Z0-819) Certification
