Java language has been evolving at a fast pace with the six month release cadence and preview features. These Language features will be discussed in detail in the talk "What's new in Java?". Eclipse IDE provides a list of UI features built on top of this Java language support. Hence, Eclipse IDE also needs to keep pace with the new Java release cycle with support added in UI for the new features- both standard and preview. These Java 14 and 15 features would include Switch Expressions, Records, Text Blocks, Pattern InstanceOf, and Sealed Types.
Having read the specification at the evolution phases as a JSR member and then having implemented some of these language features in the Eclipse Java Compiler (ECJ) of Java Development Tools (JDT), planning to bring in the perspective of "why" a particular feature exists in the first place. Of course, I will be covering the "what" in detail, and then planning to go into a few major characteristics of each feature to help the attendee go beyond the "dry" lecture of different language features.
