How to Leverage Pattern Matching for instanceof in Java

Pattern matching for instanceof is a feature introduced in Java 16 that simplifies the process of checking an object's type and casting it to a specific type. It enables you to combine the type-check and type-cast operations in a single line of code, making your code more concise and readable.

Here's how it works: when using instanceof, you can declare a new variable immediately after the type that you're checking against. If the object is an instance of the specified type, the new variable will be automatically cast to that type.

This code example demonstrates how to use pattern matching for instanceof in Java. The traditional instanceof check and type casting are shown first, followed by the Java 16+ pattern matching for instanceof usage. The second example is more concise and easier to read.
