And a `description`:

      if (expectedOldCount != 0) {
        return false;
      } else if (newCount == 0) {
        return true;

        // if our write lost the race, it must have lost to a nonzero value, so we can stop

   *   <li>The visible constructor or visible static factory method with the most parameters is used
   *       to construct the sample instances. In case of tie, the candidate constructors or
   *       factories are tried one after another until one can be used to construct sample
   *       instances.

In many cases your application could need some external settings or configurations, for example secret keys, database credentials, credentials for email services, etc.

Most of these settings are variable (can change), like database URLs. And many could be sensitive, like secrets.

For this reason it's common to provide them in environment variables that are read by the application.
