In this course, we will thoroughly explore the key innovations in Java 12, 13, 14, 15, 16, and 17. It is ideal for programmers working with Java 11 and needing to update their knowledge, as well as for those who are already using Java 17 but have not fully grasped all the nuances of the new versions. We will start with language improvements: we'll look at how NullPointerExceptions now provide more useful debugging information, explore new features of switch expressions, text blocks, pattern matching for the instanceof operator, records, and final sealed classes. Next, we will discuss performance improvements in Java 17, including the disabling of biased locking, the introduction of value-based classes, and the new garbage collectors ZGC and Shenandoah. In the final part of the course, we will focus on improvements to tools and APIs in Java 17, including enhanced pseudo-random number generators, deserialization filters, as well as enhanced JVM security through stricter encapsulation and the deprecation of the legacy Security Manager.

Java Specialists thumbnail

Java Specialists is the long-running training company of Heinz Kabutz, a South African Java performance specialist who has been publishing the Java Specialists' Newsletter since 2000 — one of the longest continuously running developer publications anywhere. His material is widely respected for depth on the JVM internals and concurrency that most Java tutorials skip.

The CourseFlix listing carries three Java Specialists courses: Mastering Java 17, Java Design Patterns, and Data Structures in Java. Material is paid and aimed at experienced Java developers who want depth on the modern language and its idiomatic patterns rather than yet another framework tutorial.
