How does Pattern matching for instanceof impact performance or memory usage?

Pattern matching for `instanceof` in Java enhances performance by reducing type casting overhead and improving code readability. It can streamline the process of type checking, thereby conserving memory and execution time.

        // Example of pattern matching with instanceof in Java
        Object obj = "Hello, World!";

        if (obj instanceof String str) { // pattern matching
            System.out.println("String length: " + str.length());
        } else {
            System.out.println("Not a String.");
        }
