Java SE 12 Advanced Techniques (exam 1Z0-816 – Programmer II)

This course takes a deeper look into some of the advanced techniques and APIs available in contemporary Java, focussing specifically on Java 8 through Java 12. You’ll learn all about the new modular approach introduced in Java 9, as well as a thorough investigation of functional programming techniques via lambdas, functional interfaces, and streams. The course also covers important parts of the API including concurrency, data manipulation, and security. You can use this course as part of your preparation for Oracle exam 1Z0-816, Java SE 11 Programmer II.
