In Java, how to iterate on the constants of an interface?

Question

in an interface, I store constants in this way (I\'d like to know what you think of this practice). This is just a dummy example.

interface HttpConstants {
    /

public enum HttpConstant {
    /** 2XX: generally "OK" */
    HTTP_OK(200).
    HTTP_CREATED(201),
    HTTP_ACCEPTED(202),
    HTTP_NOT_AUTHORITATIVE(203),
    HTTP_NO_CONTENT(204),
    HTTP_RESET(205),
    HTTP_PARTIAL(206);

    private int code;
    private HttpConstant(int code) {
        this.code = code;
    }

    public int getCode() {
        return code;
    }
}

with HttpConstant.values().
