Level.java

public enum Level
{
    HIGH, MEDIUM, LOW
}

EnumDemo.java

public class EnumDemo
{

    public static void main(String[] args)
    {
        /*
         * We can obtain an array of all the possible values
         * of a Java enum type by calling its static
         * values() method.
         * 
         * All enum types get a static values() method
         * automatically by the Java compiler.
         * 
         * Notice the output how the names of the constants
         * themselves are printed out. This is one area
         * where Java enums are different than static final
         * constants.
