Are You Using Optional Wrong?

Most junior Java developers don't know the difference between orElse and orElseGet. This mistake can silently charge users of your application when it shouldn't. In this video, I show you a real-world bug where orElse executes an expensive method even when it's not needed - and how that can lead to unintended deviations in a flow. You'll learn: How orElse actually works under the hood Why orElseGet is the safer choice for expensive operations A practical example that makes the difference crystal clear If you've ever used Optional in Java, watch this before shipping your next feature.
