switch statement

Du kan switche på forskellige typer, som int, char, boolean osv eksempel:
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;
        }
    }
   
    public static void main(String[] args) {
        EnumTest firstDay = new EnumTest(Day.MONDAY);
        firstDay.tellItLikeItIs();
        EnumTest thirdDay = new EnumTest(Day.WEDNESDAY);
        thirdDay.tellItLikeItIs();
        EnumTest fifthDay = new EnumTest(Day.FRIDAY);
        fifthDay.tellItLikeItIs();
        EnumTest sixthDay = new EnumTest(Day.SATURDAY);
        sixthDay.tellItLikeItIs();
        EnumTest seventhDay = new EnumTest(Day.SUNDAY);
        seventhDay.tellItLikeItIs();
       
       
    }
}
