  • The point is also to minimize potential damages caused by a bug in the software. Just this year there have been multiple data-destroying bugs in publicly released software. If the app runs as a server it’s usually trivial to have it run as a dedicated user, with just enough permissions to do its job.

    It’s just good practice, even though the risks might be low why risk it at all?





  • Nah, Hibernate, Spring and most major Java frameworks have largely moved away from XML. It’s still supported, but these days it’s mostly configured in the code directly, with properties loaded from yaml, JSON or the environment (for containers).

    The JDK ecosystem is in a pretty good spot nowadays. With Spring boot you can whip up a productions ready back-end very fast, or if you prefer a more hands-on approach there are lighter frameworks/libraries quarkus or micronaut.

    The Java language itself has evolved fast and is actually pretty nice now, and if you prefer something more modern akin to TS or swift you can just use Kotlin which is almost 100% interoperable with Java.


  • Since Java 14 it looks like this:

    Exception in thread “main” java.lang.NullPointerException:

    Cannot invoke “String.toLowerCase()” because the return value of “com.baeldung.java14.npe.HelpfulNullPointerException$PersonalDetails.getEmailAddress()” is null

    at com.baeldung.java14.npe.HelpfulNullPointerException.main(HelpfulNullPointerException.java:10)
