 Pattern Matching for Switch (introduced in Java 14)

Pattern matching for switch simplifies the common use case of performing different actions based on the value of a variable. It eliminates the need for repetitive casting and enhances code readability. Here's an example:

String day = "Sunday";

switch (day) {

    case "Monday", "Tuesday", "Wednesday", "Thursday", "Friday" ->

        System.out.println("It's a weekday.");

    case "Saturday", "Sunday" ->

        System.out.println("It's a weekend day.");

    default ->

        System.out.println("Invalid day.");

}
