Day - 11 Enum and learning

 

// 🔢 What are Enums and Why Should You Use Them?

// Ever needed to represent a fixed set of values — like days of the week,

payment statuses, or user roles?

// That’s where Enums shine! 🌟

// 📌 What is an Enum?

// Short for Enumeration, an enum is a special “type” that defines a collection of

named constants.

// Think of it as a predefined list of allowed values.

// ✅ Why Use Enums?

// ✅ Type Safety – Prevents invalid values

// ✅ Readability – Names over magic numbers/strings

// ✅ Maintainability – Easy to update and extend

// ✅ Built-in Methods – .values(), .ordinal(), .name()

public class enum_orderStatus {

    //  Create enum (fixed set of values)

 enum OrderStatus {

        ORDERED,

        PACKED,

        SHIPPED,

        OUT_FOR_DELIVERY,

        DELIVERED

    }

   

    public static void main(String[] args) {

       

        //  Use enum

          OrderStatus status = OrderStatus.SHIPPED;

        //  Print status

        System.out.println("Your order status is: " + status);

    }

    }
