New Features in Java 11

Java Training Overview

Accelebrate's New Features in Java training course walks attendees through the important new features through Java 11 LTS and provides an overview of the new features in Java 12+ that are also likely to appear in Java 17 (the next LTS release). Students learn how to leverage the new Java Platform Module System (JPMS), which presents a fundamental shift in how applications are organized and interconnected to the libraries they use. Participants learn how to use modules and explore migration from non-modular applications.

Objectives

• Understand the new Java release cycle and Long Term Support (LTS) releases
• Be familiar with significant deprecated and removed features, and how to work around them
• Create and use Java modules, understanding module descriptors, modular JARs, exports and dependencies, and the modulepath
• Understand the structure and behavior of the modular JDK, how it supports modular applications as well as legacy classpath-based code, and the implications of strong encapsulation on each
• Migrate classpath-based applications to Java 11, understanding the stages of migration and options available
• Recognize the issues with 3rd party libraries in a migration effort, and how to work with them on the modulepath and classpath
• Use local-variable type inference with var, including lambda parameters
• Gain a practical working knowledge of the JShell REPL tool, including working with code snippets and variables, configuration, and using external libraries
• Use the HTTP Client to access HTTP resources from Java, as well as understand the other options available
• Work with various HTTP request and response types, using both synchronous and asynchronous techniques
• Outline the new factory methods in Java Collections and understand native immutable collections
• Describe the motivation for multi-release JAR files (MR-JARs), understand their structure, and how to create them
• Understand the runtime behavior of MR-JARs in both legacy and modern JVMs, and principles and strategies for working with them effectively
• Outline the principles of Reactive Programming and how it differs from traditional synchronous invocation models
• Describe Reactive Streams and the role of the Flow API that defines the Java platform’s support for them
• Understand the characteristics and benefits of custom runtime images
• Use jdeps to analyze application dependencies, and create custom runtimes with jlink, for both modular and classpath-based applications
• Explore some of the more important additional features and APIs, including new features for interfaces, the Process API, new JDK tools and command line options
