One issue with unboxing in Java that always throws exception
In this video I uncover a subtle but potentially harmful issue related to unboxing in Java. If you've ever encountered a mysterious `NullPointerException` when working with object wrapper types and primitive types, this video is for you!
In Java, unboxing refers to the conversion of an object of a wrapper type to its corresponding primitive type. But what happens when that object has a null value? If you're not careful, this can crash your app with a frustrating `NullPointerException`.
Fortunately, Java 14 introduced helpful `NullPointerException` messages, making it easier to diagnose the issue. However, that doesn't prevent your app from crashing. In this video, I'll demonstrate with code examples what exactly goes wrong, and why it's an issue that you might overlook, even in your tests.
So, what's the best practice? Always check for null values before unboxing, or stick to primitives where possible for safety. I'll explain all of these and more.
