Java SE Advanced Techniques (Course II for exam 1Z0-819)

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 11. 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.


What you will learn:

  • Modular Java
  • Functional programming techniques
  • Effective concurrency
  • Data access techniques
  • Security
  • Localization
