Answer 1

You definitely can switch on enums. An example posted from the Java tutorials.

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

public class EnumTest {
    Day day;

    public EnumTest(Day day) {
        this.day = day;
    }

    public void tellItLikeItIs() {

        switch (day) {
            case MONDAY: 
                System.out.println("Mondays are bad.");
                break;

            case FRIDAY: 
                System.out.println("Fridays are better.");
                break;

            case SATURDAY:
            case SUNDAY: 
                System.out.println("Weekends are best.");
                break;

            default:
                System.out.println("Midweek days are so-so.");
                break;
        }
    }
}
