Optional Class

The hunt for null values in our code can often feel like looking for a needle in a haystack. We all know the pain of NullPointerExceptions, those unexpected crashes that arise when we try to access methods or properties on null objects.

Thankfully, Java has come to the rescue with the Optional class, a tool that encourages us to think more carefully about nullability.

Using Optional can lead to cleaner, more reliable code. It helps us express the possibility of absence, making our intentions clearer. So, let’s dive deep into the Optional class, exploring its features, use cases, and some common pitfalls to watch out for.
