Mobile.java

enum Mobile
{
    Samsung(500), 
    Nokia(300), 
    Motorola(400);

    int price;

    Mobile(int price)
    {
        this.price = price;
    }

    int getPrice()
    {
        return price;
    }
}

EnumDemo.java

public class EnumDemo
{
    public static void main(String args[])
    {
        System.out.println("Mobile Phone List:");
        System.out.println("-------------------");
        
        Mobile[] mobileArray = Mobile.values();
        
        for (Mobile mobile : mobileArray)
        {
            System.out.println(mobile + " costs " + mobile.getPrice()
                    + " dollars");
        }
        System.out.println("-------------------");
        
        Mobile mobile = Mobile.Motorola;
        /*
         * Returns the name of this enum constant, exactly
         * as declared in its enum declaration.
         */
        
        String mobileName = mobile.name();      
        System.out.println("\nMobileName = " + mobileName);

    }
}
