Java 9-11 Update

Starting with the release of Java 9 in September 2017, new Java language versions are now developed every six months; according to the plan, only one version per three year period will receive long-term support. Java 11 is the first release with long-term support since Java 8.
Many developers will therefore move straight from Java 8 to Java 11, meaning they will have to get to grips with the new features from three major releases.
After years of planning, the Java Platform Module System (JPMS) was introduced in Java 9 under the code name Jigsaw. The main focus was on modularizing the Java class library. Modularization is an important aspect of software architecture. Many developers and architects have been waiting a long time for this.
In this seminar, we will provide you with the basic principles for dividing your applications correctly and differentiating the components clearly from one another. This will minimize potential problems with migration or new implementations. We will also look at the support provided by the development environments and build management
as well as discussing other new features, including JShell, the new keyword "var", and enhancements to the Process API, Collection, and Stream API. The seminar offers a simple introduction to the new features of Java 9–11 and provides valuable information and practical tips.
