Development with Java® SE. Extended
опис
This training is a continuation of the Java for Beginners trainings and covers the most important features currently in use.
You will work with essential Java classes, learn how to use multithreading (both at the level of core mechanisms and java.util.concurrent library) and the reflection mechanism. We will also work on defining and using annotations, logging into programs, and apply Java’s most important features (lambda expressions, references to methods, streams, the new Date and Time API, etc.).
