What functions are available for use with enums in your programming language?

In Java, enumerations (enum) are a special type that represents a fixed set of constants. Besides storing a set of named values, enums in Java have the following features:

• Methods and fields: Enums can define fields, constructors, and methods, allowing to store additional information and behavior for each element.
• values() method: Returns an array of all enum elements in the order they are declared.
• valueOf(String name) method: Returns the enum element with the specified name.
• Comparison: Enum elements can be compared using == and compareTo(), as they are singletons.

Example:

public enum Day {
    MONDAY("Monday"),
    TUESDAY("Tuesday");

    private String englishName;

    Day(String englishName) {
        this.englishName = englishName;
    }

    public String getEnglishName() {
        return englishName;
    }
}

// Usage:
Day today = Day.MONDAY;
System.out.println(today.getEnglishName()); // Outputs: Monday
