Java 12 - 17 new features

One of the Long-term Support (LTS) versions of Java is Java 17, so it's already safe to use. Although there are few new features between Java 12 and 17, it is worth being aware of them, as they are an excellent indication of the direction Java is taking. These will be covered in detail in the training, whether it's a completely new language element, a completely new API, a change in the way the JVM works internally, new garbage collection mechanisms, or even just a new useful method.

Several topics are accompanied by short exercises.
