An example of an AI chatbot conversation about Java 8 Optional vs null.
What are the differences between Java 8 Optional and null?
Java 8 introduced Optional to help avoid null references. Unlike null, Optional is a container that may or may not hold a value.
Can you give me an example of how to use Optional?
Sure! You can create an Optional like this: Optional<String> name = Optional.ofNullable(getName()); This way, you can check if a value is present.
What are the advantages of using Optional over null?
Using Optional can improve code readability and reduce the risk of NullPointerExceptions by forcing you to handle the absence of a value explicitly.
Are there any downsides to using Optional?
Yes, using Optional can introduce overhead and may not be suitable for every situation, especially in performance-critical code.
