> "For example, in the following code, 7 is a magic number:
>
> 1
> int daysInAWeek = 7;
> It’s not immediately clear why 7 is used here. Is it related to the number of days in a week? Avoiding magic numbers involves giving this value a meaningful name:
>
> 1
> final int DAYS_IN_A_WEEK = 7;
> Now, it’s clear that DAYS_IN_A_WEEK represents the number of days in a week."
