Pattern Matching for switch (Java 21)

Pattern Matching for switch statements is one of the most exciting features introduced in Java 21. It allows you to write cleaner, more expressive code when dealing with complex conditions. If you’ve worked with instanceof and are familiar with the concept of pattern matching from Java 16, you’re going to appreciate how this feature enhances the switch statement.

Imagine you’re developing a system that processes different types of user input. In earlier versions of Java, handling these different cases could lead to verbose and error-prone code. With pattern matching for switch statements, we can streamline this process, making it not only cleaner but also more maintainable.
