java enum type getting a bit obfuscated

Hi I am practicing java enum these days and have been given the task of debugging some codes on these out of all i have found one very challenging here it is 

public final class ParkingAttributes extends Enum
    {

    public static final ParkingAttributes BIKE;
    public static final ParkingAttributes CAR;
    public static final ParkingAttributes CYCLE;
    private static final ParkingAttributes ENUM$VALUES[];

    private ParkingAttributes(String s, int i)
    {
        super(s, i);
    }

    public static ParkingAttributes valueOf(String s)
    {
        return (ParkingAttributes)Enum.valueOf(com/tilzmatictech/mobile/navigation/delhimetronavigator/metro/ParkingAttributes, s);
    }

    public static ParkingAttributes[] values()
    {
        ParkingAttributes aparkingattributes[] = ENUM$VALUES;
        int i = aparkingattributes.length;
        ParkingAttributes aparkingattributes1[] = new ParkingAttributes[i];
        System.arraycopy(aparkingattributes, 0, aparkingattributes1, 0, i);
        return aparkingattributes1;
    }

    static 
    {
        CAR = new ParkingAttributes("CAR", 0);
        BIKE = new ParkingAttributes("BIKE", 1);
        CYCLE = new ParkingAttributes("CYCLE", 2);
        ParkingAttributes aparkingattributes[] = new ParkingAttributes[3];
        aparkingattributes[0] = CAR;
        aparkingattributes[1] = BIKE;
        aparkingattributes[2] = CYCLE;
        ENUM$VALUES = aparkingattributes;
    }
    }

One thing i know that enum is a final class and cannot be extended what i didnt find anywhere here is that enum be defined and work of ENUM$VALUES[] Can anyone explain me the working of this code and some good tutorials to master enum thanks.

You are doing it wrong.

If you want to declare an enum, do it like this : 

public enum ParkingAttributes { //Implicitly a final class that extends Enum
  BIKE, CAR, CYCLE//Implicitly static (but not final!) instances of ParkingAttributes.
}
