What are enum extensions in different programming languages?

Enum extensions allow you to add methods or properties to enumerations in various programming languages. For example, in C#, you can use extension methods to add functionality to enums.

Can you give me an example of enum extensions in C#?

Sure! In C#, you can define an extension method for an enum like this:

public static class EnumExtensions
{
    public static string GetDescription(this MyEnum value)
    {
        switch (value)
        {
            case MyEnum.First:
                return "First Value";
            case MyEnum.Second:
                return "Second Value";
            default:
                return "Unknown";
        }
    }
}

How do enum extensions work in Java?

In Java, enums are more powerful than in many other languages. You can add methods directly to the enum class. For example:

public enum MyEnum {
    FIRST("First Value"), SECOND("Second Value");

    private String description;

    MyEnum(String description) {
        this.description = description;
    }

    public String getDescription() {
        return description;
    }
}
