Enum constants in Java are fixed values defined in an enum type, representing a set of named constants.

Can you give me an example of how to define an enum in Java?

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

How do I use enum constants in a switch statement?

You can use enum constants in a switch statement like this:

Day today = Day.MONDAY;

switch (today) {
    case MONDAY:
        System.out.println("Start of the week!");
        break;
    case FRIDAY:
        System.out.println("Almost weekend!");
        break;
    default:
        System.out.println("Just another day.");
}

Are enum constants type-safe?

Yes, enum constants are type-safe, meaning you can only use defined constants of the enum type, preventing invalid values.
