Java Enum return Int

Question

I\'m having trouble declaring an enum. What I\'m trying to create is an enum for a \'DownloadType\', where there are 3 download types (AUDIO, VIDEO, AUDIO_AND_VIDEO).

If you need to get the int value, just have a getter for the value in your ENUM:

private enum DownloadType {
    AUDIO(1), VIDEO(2), AUDIO_AND_VIDEO(3);
    private final int value;

    private DownloadType(int value) {
        this.value = value;
    }

    public int getValue() {
        return value;
    }
}

public static void main(String[] args) {
    System.out.println(DownloadType.AUDIO.getValue());           //returns 1
    System.out.println(DownloadType.VIDEO.getValue());           //returns 2
    System.out.println(DownloadType.AUDIO_AND_VIDEO.getValue()); //returns 3
}

Or you could simple use the ordinal() method, which would return the position of the enum constant in the enum.

private enum DownloadType {
    AUDIO(0), VIDEO(1), AUDIO_AND_VIDEO(2);
    //rest of the code
}

System.out.println(DownloadType.AUDIO.ordinal());            //returns 0
System.out.println(DownloadType.VIDEO.ordinal());            //returns 1
System.out.println(DownloadType.AUDIO_AND_VIDEO.ordinal()); //returns 2
