Description
Pattern matching for the `instanceof` operator is a [preview feature](http://openjdk.java.net/jeps/12) of the Java language in JDK 15. Pattern matching allows common logic in a Java program to be expressed more concisely and safely, namely the conditional extraction of components from objects. Preview features must not be used in production, but feedback from Java developers on the usability of preview features is welcome.
