Java: Pattern Matching

Pattern matching avoids the need for manual casting after instanceof checks.

In older Java, after using 'instanceof', you had to cast the object to the desired type manually. With pattern matching, this is streamlined, as the cast happens implicitly. For example, in an e-commerce system, if you want to check if an object is of type 'Customer', you can directly use: 'if (obj instanceof Customer customer)'. This not only checks the type but also casts it, making the code cleaner and less error-prone.
