Java Enhancement Proposal 354

Java Enhancement Proposal 354 (JEP 354) introduces a new pattern matching feature for the `instanceof` operator in Java 16. This allows developers to check if an object is of a certain type and simultaneously assign it to a variable in a single, concise statement. It simplifies code by reducing redundancy and improving readability, especially when working with type checks and subsequent casts. Essentially, it makes Java code cleaner and easier to write when handling objects of different types that require specific processing.
