With [JDK/12 EarlyAccess Build 10](http://jdk.java.net/12/), the JEP-325 Switch Expressions has been integrated as a preview feature in the JDK. A sample code for the expressions (as in the JEP as well):

```
Scanner scanner = new Scanner(System.in);
Day day = Day.valueOf(scanner.next());
switch (day) {
    case MONDAY, TUESDAY -> System.out.println("Back to work.") ;
    case WEDNESDAY -> System.out.println("Wait for the end of week...") ;
    case THURSDAY,FRIDAY -> System.out.println("Plan for the weekend?");
    case SATURDAY, SUNDAY -> System.out.println("Enjoy the holiday!");
}

```

where `Day` being an enum as 

```
public enum Day {
    MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, SUNDAY
}

```

The [Preview Language and VM Features JEP-12](http://openjdk.java.net/jeps/12) already elaborate how a feature can be enabled during compile and runtime using `javac` and `java`.

How can one try out this feature using Maven?
