How does the performance of Java 8 Optional compare to traditional null checks?

Java 8 Optional can improve code readability and reduce null pointer exceptions, but it may introduce some overhead.

What kind of overhead are we talking about?

The overhead mainly comes from the creation of Optional objects, which can be more expensive than simple null checks.

Is it worth using Optional in performance-critical applications?

In performance-critical applications, it's essential to measure and profile. If null checks are sufficient, they might be preferable.

Can you give an example of when to use Optional?

Use Optional when a method might not return a value, like in a search operation, to clearly indicate the absence of a result.
