In recent Java versions, pattern matching for switch has undergone significant enhancements, offering cleaner and more concise syntax for controlling program flow based on the type of an object. This feature allows developers to write more readable and maintainable code by eliminating the need for cumbersome casting and instanceof checks. Starting with Java 17, the preview feature paved the way for simpler usage of switch statements with pattern matching, allowing cases to directly match types.
As of the updates in Java 19, it has become more robust, supporting a wider array of patterns and including features like variable binding within the switch case itself. This creates opportunities for more expressive code that can handle complex data types without excessive boilerplate.

Learn about the evolution of pattern matching for switch statements in Java, including enhancements made in Java 17 and Java 19 that promote cleaner and more efficient code.
// Example of pattern matching in switch statement
Object obj = getSomeObject();
switch (obj) {
case String s -> System.out.println("String: " + s);
case Integer i -> System.out.println("Integer: " + i);
case null -> System.out.println("Null object");
default -> System.out.println("Unknown type");
}
