Course description
Migrating from Java 8 to Java 11 | Java 11 New Features & Skills
Migrating from Java 8 to Java 11 is a three-day, hands-on fast-track course geared for developers who have prior hands-on experience working with Java 8, who need to quickly get up and running the latest features introduced in Java 11. Throughout the course students learn the best practices for taking advantage of the new Java Module system as well as other new features in this major update to the Java programming language.
The Java 9 update introduced major changes to the core language, including new features such as the Java Module system , the introduction of JShell, as well as several small enhancements to the language as part of the ‘Milling Project Coin’ project. ‘Project Coin’ was introduced during the development of Java 7 to introduce small language changes. Milling Project Coin introduced several enhancements that did not make it into Java 7. This course provides a fast-pace, high-level overview of the some of the lesser-known languages changes that were introduced over the years. Several of these small changes have laid the foundation for the enhancements made in Java 9, 10 and 11.
