Season.java

public enum Season
{
    WINTER(5), SPRING(10), SUMMER(15), FALL(20);

    private int seasonNumber;

    private Season(int seasonNumber)
    {
        this.seasonNumber = seasonNumber;
    }

    public int getSeasonNumber()
    {
        return seasonNumber;
    }
}

EnumDemo.java

public class EnumDemo
{

    public static void main(String[] args)
    {
        /*
         * The java compiler internally adds the values()
         * method when it creates an enum. The values()
         * method returns an array containing all the values
         * of the enum.
         */
        Season[] seasonArray = Season.values();

        for (Season season : seasonArray)
        {
            System.out.println(season + ", SeasonNumber =  "
                                    + season.getSeasonNumber());
        }
