Development with Java® SE. Extended
Description
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.).

Objectives
- Use the system library essential classes in their applications: System, Math, Object, strings, wrappers
- Work with input-output from applications
- Control threads in applications
- Work with standard class collections
- Use Reflection mechanisms
- Use annotations in applications
- Use Java 8 lambdas in applications
- Use Java 8 streams in applications
- Work with the Java 8 Date and Time API
Target Audience
- Junior Java developers with knowledge of Java syntax and OOP (or those who have attended JVA-007)
- Middle Java developers who want to structure their knowledge of standard JDK libraries (I/O, collections, multithreading, data streams, etc.)
