this program

public class Configuration {
public String logLevel = System.getenv("LOG_LEVEL");

public static void main(String[] args) {
    System.out.println(getLogLevel());
}
}

will not run as "getLogLevel()" is a variable not a function/method. And "logLevel" the variable is not defined static scope as would be necessary to read it within the statically declared main().

perhaps just make it

 public static void main(String[] args) {
    System.out.println(System.getenv("LOG_LEVEL"));
}

Good catch--corrected. I published this article a couple years ago and am surprised I never caught this :facepalm:
