The Value you are providing in enum is by default 0, 1,... an so on as in array indexing. If you want to change this, you need to have value integer taken explicitly and add it in constructor as well. Also, to use this value you can have a getter as well.

Try this:

public enum Month {

    January(1),
    February(2),
    March(3),
    April(4),
    May(5),
    June(6),
    July(7),
    August(8),
    September(9),
    October(10),
    November(11),
    December(12);

    private int value;

    Month(int value) {
        this.value = value;
    }

    public int getValue() {
        return value;
    }

}
