Скачать или смотреть Java 15 New Features | Local interfaces and enums | Pattern Matching for instanceof | #02

This session will talk about Java 15 me features - Java 15 allows declaration of local enums and interfaces too – for the same reason. You can encapsulate your data or business logic, which is local to a method, within the method.

Many Java developers or programmers use the instanceof operator to check whether a given reference variable is of a certain type. They compare a reference variable to a type by using the instanceof operator. If the result is true, the next obvious step is to explicitly cast it to the type they compared it with to access its members.

Pattern Matching for instanceof is in its second preview in Java 15 (without any changes from Java 14).
